What is a site-to-site VPN with EdgeRouter?

A site-to-site VPN connects two networks securely over the internet, so devices on Network A can reach devices on Network B without exposing traffic to the public internet. EdgeRouter devices from Ubiquiti handle this with IPsec tunnels and routes, giving you a flexible, scalable solution for branch offices, data centers, or partner networks.

• Advantages

  • Centralized security between sites
  • No need for client software on endpoint devices
  • Works with multiple subnets and VLANs
  • Scales as you add more sites

• Common use cases

  • Branch office connectivity
  • Data center to remote office links
  • Backup and disaster recovery networks

Prerequisites and planning

Before you start, gather these details:

• EdgeRouter model and firmware version
• Public IP addresses for each site static is ideal, dynamic can work with dynamic DNS
• Local LAN subnets for Site A and Site B e.g., 192.168.1.0/24 and 192.168.2.0/24
• Desired IPsec parameters: encryption AES, integrity SHA, and DH group
• VPN peer public IPs or hostname

• Use a unique pre-shared key PSK per tunnel, and store it securely.
• Plan subnets to avoid overlaps. If overlaps exist, consider NAT for one side.
• Reserve management access so you don’t lock yourself out during configuration.

EdgeRouter: topologies and models

EdgeRouter devices vary, but the VPN setup steps are similar across models. The two most common topologies are:

• Hub-and-spoke: one site is the hub, others connect to it.
• Fully meshed: each site talks directly to every other site.

Your choice depends on the number of sites and traffic patterns. For a small two-site link, a direct site-to-site tunnel is straightforward and efficient.

Choosing the right IPsec settings

IPsec settings affect security and performance. Here are solid starting points:

• Encryption: AES-256 or AES-128 if you need speed and bandwidth is abundant
• Integrity: SHA-256
• DH group: MODP 2048 also known as group 14 for phase 1, and a similar group for phase 2
• IKE version: IKEv2 is more modern and supports better NAT traversal and reliability
• Perfect Forward Secrecy: enabled PFS for the IPsec SA

Note: Some older EdgeRouter firmware supports IKEv1. If you’re on older hardware, you may need to use IKEv1 with appropriate parameters.

Step-by-step setup: EdgeRouter to EdgeRouter two sites

Below is a practical, generalized outline. Adjust IPs to your network. Edge vpn app download 2026

1. Access the EdgeRouter web UI

• Open the router’s management interface https://.
• Log in with admin credentials.

2. Configure a static local LAN on each side

• Ensure both sites have distinct LAN subnets.
• Example:
  • Site A: 192.168.1.0/24
  • Site B: 192.168.2.0/24

3. Create IPsec VPN tunnel Site A as example

• Go to VPN > IPsec or Firewall/NAT depending on firmware.
• Add a new VPN peer:
  • Peer IP: Public IP of Site B
  • Authentication: Pre-Shared Key PSK
  • IKE: IKEv2
  • IKE ID: unique identifier if needed
  • Phase 1 proposals: AES-256, SHA-256, MODP2048, DH group 14
  • Phase 2 proposals: AES-256, SHA-256, PFS enabled
• Define the local and remote networks:
  • Local LAN: 192.168.1.0/24
  • Remote LAN: 192.168.2.0/24

4. Create a firewall rule to permit IPsec traffic

• Allow ESP and AH if used, and UDP ports 500 and 4500 for NAT-T
• Ensure the rule is in the correct order in your firewall policy

5. Add a static route for the remote network

• Destination: 192.168.2.0/24
• Next Hop: IPsec tunnel the VPN interface

6. Save and apply configuration

• Apply changes and monitor the VPN status.

7. Verify the tunnel

• Check tunnel status in the VPN page
• From a host in Site A, ping a host in Site B e.g., ping 192.168.2.10
• Use traceroute to confirm the path to remote subnets

8. Test bidirectional connectivity

• Ensure devices on Site B can reach devices on Site A
• Confirm firewall rules allow necessary traffic across the tunnel

Troubleshooting common issues

• Tunnel not establishing

  • Verify PSK matches on both sides.
  • Check that public IP addresses are reachable and not behind double NAT.
  • Confirm IKE and IPsec proposals match on both sides.
  • Make sure NTP is synchronized to avoid certificate drift if you use certificates.

• Traffic not flowing through the tunnel

  • Confirm that the remote subnet definitions match exactly on both sides.
  • Check firewall rules on both EdgeRouters to allow traffic across the VPN.
  • Ensure NAT is not translating traffic destined for the other network.

• Performance problems

  • Review CPU and memory usage; IPsec can be CPU-intensive on smaller devices.
  • Consider disabling unnecessary features that consume CPU.
  • If you’re bandwidth-limited, adjust encryption settings e.g., AES-128 to reduce overhead.

Advanced topics: routing, NAT, and multi-site scenarios

• Policy-based routing vs. route-based VPN

  • Route-based VPNs using a virtual tunnel interface are typically easier to manage for site-to-site.
  • Policy-based VPNs rely on specific traffic policies; they’re more granular but can be harder to maintain at scale.

• NAT traversal NAT-T Download vpn extension for edge 2026

  • NAT-T is commonly used when either site is behind a NAT device.
  • Ensure UDP ports 500 and 4500 are allowed through the firewall.

• Overlapping subnets

  • If sites share similar IP ranges, use NAT to translate traffic destined for the opposite site, or readdress one side’s network if feasible.

• Multi-site hub-and-spoke

  • Use a central hub site to which all other sites connect.
  • Create separate VPN tunnels from the hub to each spoke.
  • Implement static routes or dynamic routing protocols to manage reachability.

Security best practices

• Use strong PSKs or, preferably, certificates if supported by your EdgeRouter firmware.
• Regularly rotate keys and review tunnel configurations.
• Keep router firmware up to date with the latest security patches.
• Disable unused services on EdgeRouter to reduce attack surface.
• Enable logging and monitor VPN events to spot anomalies early.

Performance considerations and real-world numbers

• Typical VPN throughput on consumer-grade EdgeRouter devices ranges from 100 Mbps to 1 Gbps depending on model, CPU, and encryption settings.
• Offload capabilities: some models support hardware acceleration for IPsec; enabling it can significantly boost performance.
• Latency impact: VPN adds a small amount of latency due to encryption overhead; plan for a small increase in RTT between sites.
• Reliability: IKEv2 generally offers better NAT traversal and robustness in flaky WAN conditions.

Data-backed tips:

• If you’re seeing dropped tunnels or frequent reconnects, check your WAN stability first; VPN reliability depends on consistent internet connectivity.
• For remote sites with intermittent connectivity, consider keeping a keepalive or dead-peer detection to rapidly reestablish tunnels.

Real-world example: two-site branch office deployment

Imagine Site A is your headquarters with 192.168.1.0/24 and Site B is a remote office with 192.168.2.0/24. You want employees in Site B to access the HQ file servers and the internal intranet resources in Site A.

• Configure IPsec on both EdgeRouters with matching IKEv2 proposals and a strong PSK.
• Route all traffic destined for 192.168.1.0/24 through the VPN tunnel on Site B, and vice versa.
• Create firewall rules to allow internal traffic between the two subnets, while blocking unnecessary inbound access from the internet.
• Test by pinging 192.168.1.10 from Site B and ensuring the response comes back through the encrypted tunnel.

As you scale to more sites, you can extend the same principles, or use a hub-and-spoke design to keep routing simple and centralized. Does touch vpn work 2026

Maintenance and monitoring

• Regularly check VPN status pages on the EdgeRouter for tunnel health.
• Set up syslog or a centralized logging solution to capture VPN events.
• Schedule periodic tests: simulate outages, verify automatic tunnel re-establishment, and ensure failover works as expected.
• Document all site-to-site VPN configurations so future admins can pick up where you left off.

Comparison: EdgeRouter vs alternative VPN solutions

• EdgeRouter IPsec VPNs are a strong fit for small to mid-size deployments, with straightforward setup and native support for IPsec.

• Alternatives like OpenVPN or WireGuard may offer easier cross-platform client support or different performance characteristics, but they require different configuration approaches and, in some cases, additional hardware.

• When to stick with EdgeRouter VPN:

  • You need a pure site-to-site IPsec tunnel between two or more EdgeRouter devices.
  • You want tight integration with the UniFi ecosystem and simple central management.

• When to explore alternatives:

  • You require client-to-site VPN for remote employees.
  • You want faster WireGuard performance with simple management across multiple devices.

Quick-reference cheat sheet

• Use IKEv2 for most scenarios
• AES-256 and SHA-256 are a solid default
• MODP 2048 DH Group 14 for Phase 1
• Enable PFS for Phase 2
• Verify both sides have non-overlapping subnets

What “site-to-site VPN” means for EdgeRouter

• A site-to-site VPN connects two distinct networks so devices on one side can reach devices on the other side as if they were on the same LAN.
• IPsec is the encryption protocol that protects traffic as it traverses untrusted networks like the Internet.
• EdgeRouter devices rely on EdgeOS Vyatta-based to configure IKE the key exchange and IPsec tunnels, plus the traffic rules needed to allow those tunnels to pass.

Prerequisites and planning

• Two EdgeRouter devices with reliable internet connections one at each site.
• A public IP address on each edge static is ideal. dynamic IPs are workable with dynamic DNS if you can’t get a static address.
• Subnet planning: ensure the LAN subnets don’t overlap. For example, Site A might be 192.168.10.0/24 and Site B 192.168.20.0/24.
• A strong pre-shared key PSK for authentication, or you can opt for certificate-based authentication if your EdgeRouter setup supports it PSK is simpler for small setups.
• Firewall awareness: you’ll need to allow IPsec-related traffic often ESP, AH, UDP 500, UDP 4500 for NAT-T and permit VPN traffic across the tunnel.
• Optional: plan for dynamic DNS if IPs aren’t static, and plan for multiple sites if you decide to scale later.

Step-by-step configuration: two-site example
Note: Replace placeholders with your real IPs, subnets, and secrets:

• SITE A: LAN 192.168.10.0/24, public IP A: a.b.c.d
• SITE B: LAN 192.168.20.0/24, public IP B: w.x.y.z
• PSK: yourStrongPsk123

set vpn ipsec site-to-site peer a.b.c.d tunnel 1 remote-subnet 192.168.10.0/24


Notes on topology and IP addressing
- If you have more than two sites, you can extend the same approach by creating additional peers: each peer needs its own local-subnet and remote-subnet mapping.
- Do not overlap LAN subnets across sites. otherwise, routing becomes ambiguous.
- For dynamic IPs, consider setting up a dynamic DNS hostname on the edge that changes and using that hostname in the peer configuration when supported, or refresh PSK and re-establish tunnels if IPs change.

Firewall and NAT considerations
- Allow the EVPN-like IPsec traffic on both ends. In practice, you’ll want to permit ESP protocol 50 and UDP ports 500 and 4500 for ISAKMP/IKE and NAT-T.
- Create a VPN firewall policy to allow traffic from VPN networks to VPN networks without NAT.
- Disable NAT for traffic between the two private subnets. you don’t want to NAT the traffic as it travels between the sites.
- A common approach is to add a firewall rule that permits traffic from the local LAN to the remote LAN via the VPN tunnel, and vice versa.

Testing and verification
- Basic checks:
  - Ensure the tunnel is up: look for an IPsec SA security association on both sides.
  - Ping across subnets: from a host on Site A to a host on Site B e.g., 192.168.10.50 -> 192.168.20.50.
  - Check routing tables to confirm the path is via the VPN tunnel and not a direct LAN route.
- Useful EdgeRouter commands:
  - show vpn ipsec sa
  - show arp
  - show interfaces tunnel
 - show logread | grep IPsec
- Troubleshooting common issues:
  - PSK mismatch: re-check the pre-shared secret on both sides.
  - Subnet overlap: verify local-subnet and remote-subnet do not overlap.
  - Firewall blocks: confirm ESP and NAT-T ports aren’t blocked by intermediate devices.
  - Dynamic IP changes: if a site’s public IP changes, re-run the tunnel rekey or update the peer configuration.

Monitoring and maintenance
- Regularly check tunnel status, uptime, and rekey intervals.
- Consider setting up alerts for tunnel down events if your environment supports it.
- For larger deployments, track multiple tunnels in a centralized dashboard or a monitoring tool, and ensure logs are stored for audit and debugging.

Security best practices
- Use strong, unique pre-shared keys or certificates if you can. Avoid default or easily guessable values.
- Keep EdgeRouter firmware updated to benefit from security fixes and stability improvements.
- Limit VPN access to the minimum necessary subnets and services.
- Periodically review firewall rules to remove any stale or unnecessary allowances.
- If you scale to more sites, consider centralized management or automation for consistency and fewer manual mistakes.

Advanced tips for EdgeRouter configurations
- If you run into intermittent tunnel drops, check MTU and MSS clamping settings. mis-sized packets can cause tunnel instability.
- For multiple remote sites, use right-sized subnets and consider route-based VPNs or policy-based VPNs depending on your EdgeOS version and support.
- If you require IPv6 site-to-site VPN, verify IPv6 addressing, firewall rules, and IPsec configurations explicitly support IPv6 on both sides.

Common pitfalls and how to avoid them
- Subnet conflicts: always double-check your LAN subnets before starting the VPN setup.
- Over-restrictive firewall rules: you can lock yourself out from the VPN if you deny VPN traffic. Start with permissive rules and tighten gradually.
- Not testing after each step: test after you set up the tunnels and again after adding routes to ensure traffic actually flows through the VPN.

Scaling beyond two sites
- When adding more sites, replicate the peer and tunnel setup for each site, keeping individual PSKs or certificate identities distinct.
- Plan a consistent naming scheme for peers and subnets to avoid confusion as you scale.
- Consider a hub-and-spoke design if you have many sites requiring inter-site communication, which can simplify routing tables and reduce complexity.

IPv6 considerations
- If you need IPv6 site-to-site VPN, ensure your EdgeRouter supports it and that the IPv6 subnets are distinct on each side.
- Update firewall rules to handle ESP/UDP 500/4500 for IPv6, as some devices treat IPv6 traffic a bit differently than IPv4.

FAQ: Frequently asked questions
# What is Edgerouter vpn site to site?
Edgerouter vpn site to site is a configuration that creates a secure IPsec tunnel between two EdgeRouter gateways to connect different networks over the Internet, enabling devices on one site to reach devices on the other as if they were on the same LAN.

# Do I need two EdgeRouter devices to make a site-to-site VPN work?
Yes. A site-to-site VPN requires two gateways at the very least, one at each site, to establish a tunnel that encrypts traffic between the two networks.

# Should I use IKEv1 or IKEv2 for EdgeRouter site-to-site VPN?
IKEv2 is generally preferred for modern networks because it re-establishes quickly after outages, is more secure with fewer configuration quirks, and tends to work better with NAT-Traverse. If you’re maintaining an older EdgeRouter setup, IKEv1 is still possible but consider upgrading where feasible.

# How do I choose local and remote subnets?
Pick non-overlapping private subnets for each site. For example, Site A can be 192.168.10.0/24 and Site B 192.168.20.0/24. The key is that routers know which side owns which subnet so traffic can route correctly.

# What if my public IPs aren’t static?
You can use dynamic DNS DDNS to keep a hostname updated with your current IP. On many EdgeRouter setups, you can point the peer to the hostname rather than a fixed IP and refresh the tunnel automatically when the IP changes.

# How do I test a site-to-site VPN after configuring it?
- Verify the tunnel status look for an active IPsec SA.
- Ping hosts across subnets Site A to Site B.
- Check routing to ensure traffic takes the VPN path.
- Use traceroute to confirm the path and identify where it breaks if it doesn’t work.

# What firewall rules are essential for IPsec VPNs?
Allow IPsec-related traffic: ESP protocol 50, UDP 500 ISAKMP, UDP 4500 NAT-T. Then ensure there are rules permitting traffic between VPN subnets across the tunnel and blocking unsolicited inbound traffic as appropriate.

# Can I have multiple site-to-site VPNs on the same EdgeRouter?
Yes, you can configure multiple IPsec peers, but you’ll need separate tunnel definitions for each peer and corresponding firewall and routing entries. Keep things organized with clear naming.

# How do I handle overlapping subnets if I expand later?
Plan subnets now with future growth in mind. Use non-overlapping ranges for each new site and document every change. If a conflict arises, you’ll need to readdress the affected LANs and adjust VPN tunnel configurations accordingly.

# What are some common EdgeRouter pitfalls to avoid?
- PSK mismatch between sites
- Subnet overlaps
- Blocking ESP or NAT-T in firewalls
- Not updating firewall rules after adding a new VPN tunnel
- Forgetting to add static routes for remote subnets

# Is there a recommended sequence for updating firmware during VPN deployments?
Yes. Start with a stable firmware version on both EdgeRouters, then incrementally update, testing VPN connectivity after each upgrade. Always back up configurations before updating.

# Can I use a consumer VPN service for site-to-site purposes?
Consumer VPN services like NordVPN are designed for endpoint-to-endpoint privacy and not for inter-site corporate-style site-to-site VPNs. They don’t replace the need for IPsec tunnels between sites. They can complement secure remote access for individual devices, but the core site-to-site connection should be IPsec between your edge devices.

Conclusion: Note — no formal conclusion section required
This guide gives you a solid blueprint to set up Edgerouter site-to-site VPNs with EdgeRouter devices. From planning and topology to concrete EdgeOS commands and practical troubleshooting tips, you’ve got a ready-to-use framework. If you want to explore more VPN options for personal use or remote workers, check out the NordVPN promo in the introduction and decide whether a consumer VPN can complement your setup for non-site-to-site needs. Remember, the most important part is careful planning and incremental testing—build your tunnels, verify them, then expand with confidence.
