Section A — IPsec Site-to-Site VPN LAN-to-LAN
IPsec site-to-site is great when you want to extend your home or small office LAN across a secure tunnel to another gateway another office, data center, or partner network. Here’s a practical, step-by-step approach.

What you’ll need

Remote gateway IP and remote LAN subnets
Local LAN subnets behind your EdgeRouter
Authentication: pre-shared key PSK or certificates
IKE version and encryption/authentication settings compatible with the remote gateway

Step-by-step outline typical EdgeRouter CLI

Define the IKE group IKE policy and IPsec settings
set vpn ipsec ike-group IKE-G1 proposal 1 encryption aes256
set vpn ipsec ike-group IKE-G1 proposal 1 integrity sha256
set vpn ipsec ike-group IKE-G1 proposal 1 dh-group modp2048
set vpn ipsec ike-group IKE-G1 lifetime 3600
Create the IPsec peer the remote gateway
set vpn ipsec site-to-site peer 203.0.113.1 authentication mode pre-shared-secret
set vpn ipsec site-to-site peer 203.0.113.1 authentication pre-shared-secret YourPSKHere
set vpn ipsec site-to-site peer 203.0.113.1 ike-group IKE-G1
set vpn ipsec site-to-site peer 203.0.113.1 tunnel 1 local subnet 192.168.1.0/24
set vpn ipsec site-to-site peer 203.0.113.1 tunnel 1 remote subnet 10.20.0.0/24
Define the tunnel for that peer ensure you have a unique tunnel ID. 1 is common
set vpn ipsec site-to-site peer 203.0.113.1 tunnel 1
Convert and apply, then test
commit
save
restart vpn

Step-by-step outline UI alternative

In the EdgeRouter Web UI, navigate to VPN > IPsec > Site-to-Site
Add a new peer with the remote gateway IP, select PSK or certificate
Specify local and remote subnets
Apply or save, then commit and restart VPN services

Firewall and routing notes

Allow IPsec traffic: firewall WAN_LOCAL should permit ESP protocol 50 and ISAKMP UDP 500/4500. You might create a dedicated firewall rule set for VPN to avoid accidental exposure.
Traffic routing: ensure a static route or policy-based routing sends the traffic destined for the remote LAN through the VPN tunnel tunnel interface or IPsec instance.
NAT awareness: if devices behind EdgeRouter need to access the remote LAN, you’ll often disable NAT for VPN traffic or configure NAT exemption rules.
DNS considerations: consider whether VPN clients should use DNS inside the tunnel or split-tunnel to avoid VPN DNS leaks.

Section B — IPsec Remote Access VPN Individual devices
Remote access VPN lets individual devices or clients connect to your network via IPsec, establishing a secure tunnel into your EdgeRouter’s LAN.

A shared PSK or certificate-based authentication for each client device or a group-based PSK
Client configuration for the device: server address, phase 1/2 proposals, and the PSK/cert
A plan for routing: decide if all traffic or only specific subnets go through the VPN

Step-by-step outline

Create the IPsec remote-access user group and policies
set vpn ipsec auto-auth enable
set vpn ipsec ipsec-interfaces interface eth0
Define a mobile user or client profile example
set vpn ipsec remote-access ike-group IKE-G1
set vpn ipsec remote-access account user1 password YourStrongP@ssw0rd
Configure a tunnel for the client
set vpn ipsec remote-access tunnel 1 local-subnet 192.168.1.0/24
set vpn ipsec remote-access tunnel 1 remote-subnet 0.0.0.0/0
Apply, test connectivity from a client

UI path alternative

VPN > IPsec > Remote Access
Create a new user or group, configure IKE parameters, export the .ovpn-like profile if your EdgeRouter supports it
Save, apply, and distribute the connection details to clients
You’ll want VPN-specific firewall rules to allow VPN clients to access internal resources, often with a separate zone or custom rules.
If you’re using split tunneling, ensure DNS and gateway behavior on client devices matches your privacy and security goals.

Section C — OpenVPN on EdgeRouter EdgeOS
OpenVPN is a flexible option. EdgeRouter can operate as an OpenVPN client to connect to a provider or as a server for remote clients. This section covers both use cases.

OpenVPN client connect EdgeRouter to a VPN provider

A valid OpenVPN server profile from your VPN provider .ovpn file
If required, separate certificate and key files
The provider’s recommended tunnel settings proto, port, cipher, etc.

Sample approach

Prepare the OpenVPN config on EdgeRouter

Place your .ovpn or separate cert/key files in /config/openvpn/

Define a tun interface and connect using the client profile
set interfaces openvpn tun0 mode client
set interfaces openvpn tun0 dev tun0
set interfaces openvpn tun0 local-address 10.8.0.2
set interfaces openvpn tun0 remote-host the.vpn.server
set interfaces openvpn tun0 remote-port 1194
set interfaces openvpn tun0 protocol udp
set interfaces openvpn tun0 config-file /config/openvpn/yourprovider.ovpn
Route traffic through the VPN
set protocols static route 0.0.0.0/0 next-hop 10.8.0.1
Apply and test

OpenVPN server on EdgeRouter remote clients connect to your EdgeRouter

OpenVPN server configuration and CA/certs if you’re using TLS-based client authentication
Subnet for VPN clients e.g., 10.99.0.0/24

Enable the OpenVPN server
set interfaces openvpn tun0 mode server
Define server subnet and routes
set interfaces openvpn tun0 local-address 10.99.0.1
set interfaces openvpn tun0 server subnet 10.99.0.0/24
Provide client configuration or certificates

Use the OpenVPN server settings to export client profiles

Update firewall and NAT

Permit VPN traffic on the WAN and ensure routes point to the VPN clients

Apply and test

Notes and caveats

OpenVPN server on EdgeRouter can be performance-limited on older hardware. If you need many remote clients, consider offloading to a dedicated device or using a more capable router.
WireGuard support on EdgeRouter varies by firmware. If you don’t see WireGuard options in your EdgeOS UI, your firmware may not have it enabled yet or you may need to install an additional package or upgrade to a version that supports it.

Section D — WireGuard note and alternatives
WireGuard is known for speed and simplicity. EdgeRouter’s support for WireGuard depends on firmware version and model. If your EdgeRouter doesn’t natively expose WireGuard in EdgeOS, you have a few options:

Check for a firmware update that includes WireGuard support and official docs.
Use OpenVPN or IPsec as a reliable alternative, especially for a stable, widely supported remote-access VPN.
Consider a secondary device a Raspberry Pi, small PC, or a dedicated VPN gateway to run WireGuard and route traffic to EdgeRouter via static routes if you’re committed to using WireGuard for performance reasons.

Section E — Troubleshooting and maintenance

Connection drops: Double-check your PSK/cert validity, pre-shared secrets, and IKE/phase-2 settings on both sides. Mismatched transformations are a common reason for drops.
DNS leaks: If your VPN tunnel isn’t pushing DNS servers, clients may leak DNS queries. Adjust DNS settings in the VPN client config or EdgeRouter’s DNS forwarding rules to use VPN-provided DNS.
Split tunneling confusion: If only some devices go through VPN, verify policy-based routing and firewall rules to ensure the correct traffic is sent over the tunnel.
NAT and double-NAT issues: If your EdgeRouter sits behind another router, ensure NAT on the EdgeRouter doesn’t conflict with VPN traffic. In many cases, you’ll want EdgeRouter to handle VPN traffic directly on the WAN interface.
Monitoring: Use edge advanced logging to monitor VPN status and enable ping tests across the VPN tunnel to verify connectivity.

Security best practices

Use strong authentication: prefer certificates for OpenVPN where possible. for IPsec, use robust PSKs and consider certificate-based authentication if your hardware supports it.
Keep firmware up to date: VPN security relies on current security patches. Regularly upgrade EdgeOS and related packages.
Limit exposure: Only expose VPN portals and ports to trusted networks. Use firewall rules to enforce least privilege.
Regular backups: Save configurations after successful VPN setups so you can recover quickly after a device reset or upgrade.

Testing your VPN setup

Basic connectivity: From a device behind EdgeRouter, ping a host on the remote VPN subnet e.g., ping 10.20.0.1.
Route verification: Use traceroute to verify that traffic to remote subnets traverses the VPN tunnel.
DNS checks: If you route DNS through the VPN, test for DNS resolution from internal clients over VPN e.g., nslookup to internal resources to confirm DNS routing works.
Web access tests: If you route internet traffic through the VPN, test access to public websites to confirm the VPN exit node is functioning.

What you should do next

If you’re starting from scratch, pick a path: IPsec site-to-site for gateway-to-gateway, IPsec remote access for individual devices, or OpenVPN if you have a provider or want to host OpenVPN.
Validate your network design: ensure subnets do not overlap, verify firewall rules, and confirm NAT behavior aligns with your VPN goals.
Iterate on the setup: most EdgeRouter VPN configurations require some tuning after you test with real devices.

How do I enable DNS over VPN?

Configure VPN client or server to push the correct DNS servers, or set DNS forwarders on EdgeRouter so VPN clients always resolve DNS through the VPN provider’s DNS. If you’re using OpenVPN, you can push the DNS server to clients via the server config. Xbox edge vpn

What’s the difference between IPsec and OpenVPN for EdgeRouter?

IPsec is generally faster for site-to-site and remote access with hardware acceleration, and it integrates well with enterprise-grade networks. OpenVPN is highly configurable and widely supported, including on client devices, and it’s often easier to set up with VPN providers.

Section F — Quick tips and best practices

Start simple: begin with a basic IPsec site-to-site or a simple OpenVPN client setup to establish a baseline.
Document everything: keep a quick reference of VPN peer IPs, PSKs, subnets, and firewall rules.
Test intermittently: run periodic tests to ensure the tunnel remains healthy, especially after firmware updates.
Use backups and staging: test changes in a staging environment if you can, then push to production.
