Why use a site-to-site VPN on the EdgeRouter X

Keeps remote networks securely connected without exposing devices to the internet
Lets computers, printers, cameras, and servers talk across sites as if they’re in one LAN
Lower latency routing for internal traffic compared to tunneling everything through the internet

Key concepts:

Tunnels: imagine two doors that create a private corridor between sites
Phase 1 and Phase 2: establishes the tunnel IKE and then negotiates the data encryption IPsec
Security associations SAs: keep track of encryption keys and tunnel state
NAT traversal: helps VPNs work when one side sits behind a NAT device

Pre-setup checklist

Confirm internet connectivity on both EdgeRouter X devices
Decide on a public IP or dynamic DNS for each side
Choose authentication: pre-shared keys PSK or certificates PSK is simpler for most homes/SMBs
Pick a VPN type: IPsec is common and well-supported on EdgeRouter X
Note internal subnets for both LANs e.g., 192.168.1.0/24 and 192.168.2.0/24
Ensure firewall rules allow VPN traffic UDP 500, UDP 4500, ESP/IPsec as needed
Enable NTP so logs and certificates stay in sync
Update firmware to the latest EdgeRouter X version for security and bug fixes

Step-by-step setup: IPsec site-to-site VPN on EdgeRouter X

Note: commands shown are typical; adjust IPs and subnets to your environment.

Access the router

SSH into the EdgeRouter X or use the web UI at https://
It’s a good idea to back up current config before changes

Configure LAN subnets

Define the local and remote networks clearly to avoid overlap
Example:
- Local LAN: 192.168.1.0/24
- Remote LAN: 192.168.2.0/24

Create VPN peer remote gateway

Set the public IP of the remote gateway
If using dynamic DNS, enter the hostname
Example PSK: yourStrongPSK123

Define IKE Phase 1 settings

Encryption: aes256
Hash: sha256
DH group: modp2048
Key lifetime: 3600 seconds or 28800 if stable
Authentication: pre-shared key PSK

Define IPsec Phase 2 policies

Protocol: esp
Encryption: aes256
Integrity: sha256
PFS: yes Group 14
Perfect Forward Secrecy lifetime: 3600 seconds
Local subnet: 192.168.1.0/24
Remote subnet: 192.168.2.0/24

Configure a firewall rule to permit IPsec

Allow traffic for IPsec: ESP, AH if used, UDP 500, UDP 4500
Create a traffic policy that forwards VPN traffic to the tunnel

Create the VPN tunnel EdgeRouter UI or CLI

In CLI, you’ll typically run:
- set vpn ipsec peer authentication mode pre-shared-secret
- set vpn ipsec peer authentication pre-shared-secret ‘yourStrongPSK123’
- set vpn ipsec peer ike-group
- set vpn ipsec ike-group proposal 1 encryption aes256
- set vpn ipsec ike-group proposal 1 hash sha256
- set vpn ipsec ike-group lifetime 3600
- set vpn ipsec vpn-name targetip
- set vpn ipsec vpn-name ike-group
- set vpn ipsec vpn-name esp-group
- set vpn ipsec esp-group proposal 1 encryption aes256
- set vpn ipsec esp-group proposal 1 hash sha256
- set vpn ipsec esp-group pfs enable
- set vpn ipsec vpn-name local-subnet 192.168.1.0/24
- set vpn ipsec vpn-name remote-subnet 192.168.2.0/24
Commit and save

Routing and NAT

Ensure routes know how to reach the remote subnet via the VPN tunnel
Add a static route if necessary:
- Destination: 192.168.2.0/24
- Gateway: tunnel0 or the tunnel interface created
If you use NAT for internal devices, you may need to exclude VPN traffic from NAT hairpin NAT rules can be tricky

Test the tunnel

Check status in the UI or CLI
Look for “IPsec SA established” messages
Ping devices across the tunnel from each side
Use traceroute to verify path

Monitoring and maintenance

Enable logging for VPN events
Set up alerting for tunnel down events
Schedule periodic reboots or health checks if you’re in an unreliable environment
Keep firmware updated, but test updates in a controlled setting first

Common issues and fixes

Issue: VPN tunnel fails to establish
- Fix: verify PSK matches on both sides; confirm public IPs and DNS names resolve; ensure ports UDP 500/4500 are not blocked by ISP or downstream firewall
Issue: Phase 1 or Phase 2 mismatch
- Fix: align encryption, hash, and DH groups on both sides; confirm lifetime settings match
Issue: Subnet overlap
- Fix: adjust LAN subnets to avoid overlap; consider using a different addressing plan
Issue: NAT traversal problems
- Fix: enable NAT-T if behind NAT devices; ensure NAT-T settings are consistent
Issue: Slow performance
- Fix: consider reducing encryption overhead by tuning packet sizes and MTU; ensure hardware resources aren’t maxed out
Issue: Dynamic DNS not updating
- Fix: verify DNS client on the router is active and refresh intervals are reasonable
Issue: DNS leaks or name resolution problems
- Fix: ensure DNS settings on clients don’t bypass the VPN; use internal DNS servers if possible

Security best practices

Use strong PSKs or certificates; rotate keys periodically
Restrict VPN access to only the necessary subnets
Keep EdgeRouter X firmware updated
Disable unused services to reduce attack surface
Enable logging and monitor for unusual states or repeated failed attempts
Use MFA where possible for management interfaces
Regularly back up configs and store them securely
Consider incident response steps: how you’ll handle a compromised site

Performance optimization tips

Use aes256 for strong encryption without excessive CPU load
Keep MTU/GRE issues in check; test with small packet sizes
Prefer wired connections for VPN gateways over wireless when possible
If you have multiple VPN tunnels, balance traffic by policy-based routing or use dynamic routing protocols with VPN support
For high-latency links, adjust IKE retransmit and SA lifetimes to reduce reconnection storms

Advanced topics

Remote Subnet: 192.168.2.0/24
NAT-T: Enabled if behind NAT
Firewall: Allow ESP, UDP 500, UDP 4500

Real-world example: small office to home office

Local site: small office with 192.168.1.0/24
Remote site: home office with 192.168.2.0/24
Public IPs: office – 203.0.113.10, home – 203.0.113.20
PSK: HomeOffice123
Steps mirrored from above, with:
- IKE group: modp2048
- ESP group: aes256-sha256
- PFS: enabled
Result: devices from both sites reach printers, NAS, and internal servers with low latency and no need for VPN clients

Troubleshooting quick checklist

VPN tunnel status: SA established or not
Logs: look for negotiation errors or mismatches
Subnet overlap: confirm no IP ranges collide
Connectivity: can you ping remote gateway and remote hosts
Firewall rules: ensure VPN traffic is permitted through
MTU: test with ping -f -l 1400 to adjust packet size
Clock/time: confirm both sides have synchronized time for certificates

More tips for reliability

Keep a small, readable network diagram with IPs, subnets, and device roles
Document tweak changes and test one thing at a time
If you’re rolling this out to multiple sites, create a standard config template
Schedule quarterly reviews of firewall rules to remove outdated items

What you’ll need

Two EdgeRouter X devices or EdgeRouter X paired with another IPsec gateway with firmware updated to the latest stable release.
Public static IPs or dynamic DNS for each edge device dynamic DNS can work, but static IPs are simpler for a stable tunnel.
Basic LAN addressing plan for both sides e.g., 192.168.1.0/24 on Site A and 192.168.2.0/24 on Site B.
SSH access to both EdgeRouter X units or the GUI, if you prefer.
A small notebook for recording VPN parameters and tested routes.

Network diagrams and assumptions

Site A LAN: 192.168.1.0/24
Site B LAN: 192.168.2.0/24
EdgeRouter X devices located behind NAT on local networks; actual public IPs are known to you.
Important: ensure both sites can reach each other over the internet ping or traceroute as a quick check.

Planning your VPN parameters

Encryption and integrity: AES-256 with SHA-256 is a solid balance of security and performance.
VPN tunnel mode: IKEv2 is preferred for stability and quicker rekeying; however, many setups still use IKEv1 for compatibility. Choose one and stick with it on both sides.
Phase 1 IKE proposals: you might see options like AES256-SHA256; modp1536 or 2048 for Diffie-Hellman DH groups.
Phase 2 IPsec proposals: AES-256 with SHA-256, PFS perfect forward secrecy enabled, typically using a DH group like 14 2048-bit or 19 Diffie-Hellman group for IKEv2.
PFS: enable for Phase 2, with a reasonable lifetime e.g., 3600–14400 seconds.
IKE/IPsec lifetimes: common values are 28800 seconds for IKE and 3600 seconds for IPsec; equal values on both sides ensure a clean rekey.
Local and remote networks: define your LAN subnets clearly to avoid overlaps.
Dead Peer Detection DPD: enable to detect dead tunnels quickly and reestablish.

EdgeRouter X: initial hardening and prerequisites Edgerouter show vpn config guide for EdgeRouter IPsec, L2TP, and VPN status viewing and troubleshooting 2026

Access methods: enable SSH or use the graphical interface New UI if available.
Firmware check: confirm you’re on the latest stable release compatible with your hardware.
Time sync: ensure both devices have accurate time NTP to prevent certificate or SA negotiation issues.
Backup: snapshot a configuration backup before making changes.
Firewall posture: keep a minimal set of rules open to VPN ports to reduce exposure during setup.

Site-to-Site VPN configuration: Step-by-step

Step 1: Create a new VPN peer on Site A
- Local gateway IP: your Site A public IP
- Remote gateway IP: Site B public IP
- IKE version: IKEv2 or IKEv1 if you’re constrained
- IKE proposals: AES256-SHA256 with DH group 14 2048-bit
- IPsec proposals: AES256-SHA256 with PFS group 14
- SA lifetime: IKE 28800, IPsec 3600
- Authentication: pre-shared key PSK or certificate-based if you prefer, but PSK is simpler for most home/small-office setups
- Local subnets: 192.168.1.0/24
- Remote subnets: 192.168.2.0/24
Step 2: Create a matching VPN peer on Site B
- Mirror all values: remote/local reversed, same PSK, same proposals and lifetimes
Step 3: Define VPN interfaces or tunnels
- Bind the IPsec SA to the local interface if required by your EdgeRouter interface naming
Step 4: Add routing
- On Site A: route 192.168.2.0/24 via the VPN tunnel
- On Site B: route 192.168.1.0/24 via the VPN tunnel
Step 5: Firewall rules for VPN traffic
- Allow IPsec ESP, AH if used, and IKE on the WAN interfaces
- Allow NAT-T if you’re behind NAT most setups will need NAT-T
- Ensure the VPN traffic isn’t blocked by LAN firewall rules
Step 6: NAT considerations
- Avoid overlapping NAT rules on the VPN networks
- If you need to access internet resources from VPN clients, you can enable split tunneling or full-tunnel policies later
Step 7: Bring the tunnel up
- Save changes and force a re-negotiation
- Check the status for ISAKMP IKE and IPsec SA under the VPN section
Step 8: Verification
- Ping a host in the opposite site LAN e.g., from 192.168.1.x to 192.168.2.x
- Check that traffic is traversing the VPN tunnel look at tunnel statistics and SA status
- Verify MTU/fragmentation isn’t causing drops adjust MTU if you see packet loss
Step 9: Post-setup testing
- Drive-by tests: small file transfers, latency checks, and jitter measurements
- Simulate failover: disconnect the internet on one site and restore to ensure the tunnel reestablishes automatically

Traffic selectors and routing considerations

Narrow IP ranges for traffic selectors to minimize unnecessary tunnel use
If you have overlapping subnets, consider readdressing one side or using NAT to isolate traffic
Use policy-based routing only if you need traffic from specific hosts to go through the VPN; otherwise, route-based VPNs keep things simpler

Firewall and NAT rules for VPN traffic

Inbound rules: allow UDP 500 ISAKMP and UDP 4500 NAT-T if NAT is involved; allow ESP if your device requires it
Outbound rules: permit VPN negotiation traffic to the internet
VPN traffic rules: ensure traffic from the VPN interfaces to the remote LAN is allowed
NAT: if you use NAT for VPN clients, ensure NAT is not applied to VPN traffic between sites, or set appropriate exemptions

Verification and troubleshooting

Basic checks:
- IPSec SA status shows Up on both sides
- IKE negotiations completed with expected lifetime values
- Pings across sites succeed 192.168.1.X -> 192.168.2.X
Common issues and fixes:
- Mismatched PSK: re-check PSK strings on both ends
- Mismatched IKE/IPsec proposals: align encryption, integrity, and DH groups
- Time skew: fix NTP on both devices
- Firewall blocking: temporarily loosen rules to confirm tunnel establishment
- NAT-T issues: ensure NAT-T is enabled if behind NAT
- Overlapping subnets: readdress or segment networks
Performance checks:
- Verify throughput vs. expected tunnel capacity EdgeRouter X should handle typical small-to-medium VPNs well
- Check CPU load during peak times and right-size policies if needed
- Consider enabling hardware offload if available on your firmware

Best practices to maintain a healthy VPN Does microsoft edge have vpn and how to use a VPN with Edge on Windows 11 and Windows 10 in 2026

Use consistent naming and documented parameters
Keep firmware up to date and backup configs before upgrades
Regularly test tunnel connectivity and failover
Use strong, unique PSKs and rotate them periodically
Monitor tunnel health with SNMP, a logging system, or a VPN health dashboard
Minimize exposed services on edge devices to reduce attack surface
Review firewall rules quarterly to ensure they match your current network needs
Consider redundancy: a second ISP or a secondary VPN path for business continuity

Common mistakes to avoid

Mixing IKEv1 and IKEv2 on the same tunnel or devices
Using mismatched encryption or hash algorithms
Overlapping LAN subnets across sites
Relying on a single edge device without backup configuration copies
Forgetting to update firewall rules after topology changes

Frequently Asked Questions

Q: Can I use a dynamic IP on one site?
A: Yes, but it complicates the setup. A dynamic DNS service helps the other side keep track of the changing IPs.
Q: What’s the difference between IKEv1 and IKEv2 for this setup?
A: IKEv2 is more modern, usually easier to configure, and provides better performance and stability. If possible, use IKEv2 on both sides.
Q: Do I need to use a pre-shared key?
A: PSK is the simplest method for most setups. Certificates are more scalable for larger deployments but add complexity.
Q: How can I verify the tunnel is actually carrying traffic?
A: Use ping tests across subnets, review the IPsec SA counters, and monitor MTU if you see fragmentation.
Q: What if the VPN tunnel drops?
A: Check ISAKMP/IKE/SA status, verify connectivity, and ensure remote site isn’t blocking the tunnel. Re-establish the tunnel if needed.
Q: Should I enable NAT on VPN traffic?
A: Only if necessary for your topology. NAT can complicate routing; try to avoid it for site-to-site traffic and keep split-tunneling simple.
Q: How do I handle multiple remote sites?
A: Create separate VPN peers for each site, ensure non-overlapping subnets, and set up distinct routing policies for each tunnel.
Q: Is IPsec the only option for EdgeRouter X site-to-site?
A: IPsec is the standard and widely supported. Some alternatives exist, but IPsec remains the most reliable choice for site-to-site VPNs.
Q: Can VPNs support remote access clients as well?
A: Yes, but that typically involves a separate VPN configuration e.g., OpenVPN or L2TP and is managed differently from a site-to-site tunnel.
Q: What performance should I expect on EdgeRouter X?
A: EdgeRouter X handles basic VPN traffic well. If you’re saturating the link or have many simultaneous tunnels, monitor CPU and consider offloading or upgrading to a more capable router.

Notes and tips

Keep a simple, clean topology to minimize debugging time during outages.
Document every parameter you configure PSK, subnets, local/remote IDs in a secure document for future reference.

What is a site-to-site VPN and why EdgeRouter X

A site-to-site VPN IPsec creates an encrypted tunnel between two networks, letting devices on either side communicate as if they were locally connected.
EdgeRouter X is a compact, affordable router that supports IPsec and can be configured via EdgeOS CLI or GUI. It’s ideal for small offices and remote sites.
IPsec offers strong protection for data in transit between sites, with options for AES encryption, SHA-256 hashing, and robust authentication via pre-shared keys or certificates.
When used correctly, site-to-site VPNs reduce exposure to the public internet, simplify remote access for branch offices, and help you centralize resource sharing.

Prerequisites and network diagram

Hardware and firmware:
- Ubiquiti EdgeRouter X unified gateway at site A or B
- Latest EdgeOS firmware installed check Ubiquiti’s site for updated builds
Network basics:
- Public WAN IPs for both sites static preferred. dynamic with a dynamic DNS workaround if needed
- Private LAN subnets at both sites e.g., Site A: 192.168.10.0/24, Site B: 192.168.20.0/24
- VPN tunnel endpoints defined by public IPs
Security and routing basics:
- Pre-shared key PSK or certificate-based authentication for the IPsec tunnel
- Correct firewall rules to allow VPN traffic ESP, ISAKMP/IKE, UDP 500/4500, etc.
- Static routes or dynamic routing in your network to ensure traffic destined for the remote LAN goes through the VPN
Common gotchas:
- NAT on the path you’re using for admin access shouldn’t interfere with VPN traffic
- Subnet overlap between sites must be avoided or carefully planned
- If either site sits behind double NAT, you’ll need NAT-T and port-forwarding where applicable

EdgeOS vs GUI vs CLI:
- The EdgeRouter X can be managed via the graphical user interface GUI in EdgeOS or via SSH/console with the CLI. The GUI is friendlier for quick setups, while the CLI provides precise control and repeatability for complex topologies.
IPsec at a glance:
- You’ll define an IPsec “IKE group” IKE phase 1 settings, an ESP/IPsec “proposal” phase 2 settings, and the “site-to-site peer” the remote gateway to tie everything together.
Firewall zones and NAT:
- Create firewall rules that explicitly permit IPsec negotiation and tunnel traffic.
- Add NAT exemption so traffic destined for the remote LAN doesn’t get NATed on either side.
Naming conventions:
- Use clear, consistent names: e.g., IKE-GROUP IKE-2, ESP-GROUP ESP-2, PEER SITE-B, etc. This makes troubleshooting much easier.

Step-by-step guide: configuring a site-to-site VPN on EdgeRouter X
Note: The exact values IP addresses, subnets, keys must be replaced with your real network details. The commands below are representative and should be adapted to your environment.

- ESP Group: ESP-GROUP-DEFAULT
- Local LAN: 192.168.10.0/24
- Remote LAN: 192.168.20.0/24
Firewall/NAT exemptions:
- Create a firewall rule to allow ESP 50 and AH 51 traffic, and IKE UDP 500 and NAT-T UDP 4500 as needed.
- Add NAT exemption for traffic destined for 192.168.20.0/24 Site B and 192.168.10.0/24 Site A so VPN traffic isn’t NATed.
Apply and test:
- Save, apply, and use the “Test” or “Ping” features to test connectivity across the VPN.

Tips for success with EdgeRouter X IPSec VPN

Pick a stable topology:
- If possible, keep subnets on each site non-overlapping e.g., 192.168.10.0/24 vs 192.168.20.0/24. If you must overlap, plan a NAT or route-based approach and be prepared to address route leakage.
Use a strongPSK and rotate it periodically:
- For production, consider certificates if you have webhook or centralized management.
Optimize for performance:
- AES256 and SHA256 provide a solid balance of security and performance on EdgeRouter X.
- Check the device’s CPU load during VPN negotiation. EdgeRouter X has modest headroom, so avoid overloading it with additional VPN tunnels or heavy routing.
NAT traversal and dynamic IPs:
- If the remote site has a dynamic IP, use dynamic DNS or a VPN peer that supports dynamic endpoints. NAT-T helps when the path uses NAT between sites.
Troubleshooting quick checks:
- Double-check firewall rules: allow UDP 500, UDP 4500, and ESP 50 on both sides.
- Confirm that the remote gateway accepts your PSK and that the IKE and ESP groups match on both sides.
- Look at log messages System > Logging for VPN negotiation errors and fix mismatches promptly.
- Validate routes on both sides to ensure traffic is being routed through the tunnel.

Common pitfalls and troubleshooting tips

Subnet mismatch:
- If you see no traffic across the tunnel, verify that the local and remote LAN prefixes are correct and that the remote site actually uses those prefixes.
NAT issues:
- If VPN traffic is getting NATed, ensure NAT exemptions are properly configured so VPN peers see the true endpoints.
Phase 1/Phase 2 negotiation failures:
- Ensure IKE group and ESP group match exactly on both sides. A single mismatch will halt the tunnel.
Dynamic IP on either side:
- If one end uses a dynamic IP, you’ll want to rely on a DDNS service or a VPN peer that supports dynamic endpoints with proper keepalive.
Firewall misconfigurations:
- Avoid overly broad rules that could inadvertently allow traffic that conflicts with VPN security goals. Keep rules specific to VPN traffic.

Security considerations

Use strong authentication:
- Prefer long, random PSKs. consider certificates if your infrastructure supports it.
Harden firewall rules:
- Only allow necessary VPN traffic ESP, ISAKMP, UDP ports as required and restrict admin access to trusted networks.
Monitor VPN health:
- Enable logging for VPN events and periodically check for dropped tunnels or rekey events.
Regular maintenance:
- Keep EdgeRouter X firmware up to date, review VPN configs after network changes, and rotate keys on a schedule.

Encryption overhead:
- AES256 is secure, but AES128 can be faster on some hardware. Test and choose the right balance for your devices and traffic volume.
Tunnel uptime:
- If you require high uptime, configure dead-peer detection DPD and keepalive settings so the tunnel recovers quickly after a transient outage.
Traffic shaping:
- If you’re running multiple services through the VPN, consider prioritizing critical business traffic to ensure VPN performance remains stable during peak times.
