Why the EdgeRouter X can be a good VPN hub for a small network

EdgeRouter X is a five-port router with a capable EdgeOS control plane. It’s priced for home labs and small offices, yet it can handle several VPN connections if you configure it thoughtfully. The main trade-off you’ll notice is CPU power: encrypting traffic for multiple VPN tunnels lowers raw throughput compared to a high-end router. If your goal is secure remote access for a handful of devices or a single site-to-site link with one other network, EdgeRouter X is more than capable.

Key advantages:

Flexible VPN options: IPsec site-to-site, OpenVPN server where supported by firmware, and more recently WireGuard-style configurations via EdgeOS updates or community-supported features.
Fine-grained control: EdgeOS exposes firewall rules, NAT, and routing policies so you can segment VPN traffic from your LAN or from WAN.
Low cost, high reliability: a simple, stable setup that’s easy to troubleshoot and scale for a small office.

What to expect in real life: expect tens to a few hundred Mbps of VPN throughput on EdgeRouter X depending on the tunnel type, cipher suite, and remote peer hardware. For a single IPsec site-to-site link with a modest remote network, you’ll often see smoother performance than you’d expect on a budget box, especially if you keep MTU and encryption overhead in check.

VPN options you can run on EdgeRouter X

EdgeRouter X supports several VPN flavors. Here’s a practical breakdown with guidance on when to use each.

IPsec Site-to-Site recommended for most inter-office or remote network links Turbo vpn alternative for online privacy and streaming: best options in 2025 like NordVPN, ExpressVPN, Surfshark, and more
- Pros: strong security, good performance with proper profiling, widely supported by firewalls and NAT devices, easy to automate.
- Cons: setup can be fiddly if you’re new to IKE policies and NAT traversal.
- When to use: you have two networks you want to connect securely, with static IPs or stable DNS for peers.
OpenVPN Server where supported by firmware
- Pros: widely understood, client platforms have native support, good for remote-access scenarios.
- Cons: EdgeRouter X hardware can struggle with many simultaneous OpenVPN clients. newer EdgeOS builds may drop or de-emphasize OpenVPN server in favor of WireGuard or IPsec.
- When to use: you need a straightforward remote-access VPN for a smaller number of clients and you’re comfortable with possible performance constraints.
WireGuard-style or WireGuard-inspired setup via EdgeOS or community plugins
- Pros: excellent performance, simpler configuration, smaller code base, easier peer management.
- Cons: native support on EdgeRouter X depends on firmware and community tooling. you might rely on experimental or indirect implementations.
- When to use: you want high-performance VPN with simple keys and fast handshakes. ideal for modern devices that support WireGuard.
Remote access vs site-to-site
- For most home users, a site-to-site VPN between your EdgeRouter X and a second site another router is common.
- For remote work with laptops and phones, OpenVPN or WireGuard-style remote access gives you a portable tunnel.

Tip: Always start with IPsec Site-to-Site for a stable, reliable backbone first, and then consider OpenVPN or WireGuard for client access if you need it.

Step-by-step: IPsec Site-to-Site on EdgeRouter X UI-driven

This approach creates a secure tunnel between your EdgeRouter X and a counterpart another router or a firewall that supports IPsec. The steps below are UI-oriented. you’ll see the same concepts in CLI if you prefer. Big ip client edge

Prep the network

Ensure both sides have static public IPs or dynamic DNS configured.
Decide your LAN subnets e.g., 192.168.1.0/24 on your side and 192.168.2.0/24 on the remote side.
Choose a strong pre-shared key PSK and document it securely.

Enable IPsec on EdgeRouter X

Open the EdgeOS web UI usually http://192.168.1.1.
Go to VPN > IPsec or VPN > IPsec Site-to-Site depending on firmware.
Enable IPsec and create a new Site-to-Site tunnel.

Configure the local and remote endpoints

Local WAN: the public IP or hostname of your EdgeRouter X.
Remote peer: the public IP or hostname of the remote device.
Local network: the LAN behind your EdgeRouter X e.g., 192.168.1.0/24.
Remote network: the LAN behind the remote device e.g., 192.168.2.0/24.

Set the IKE policy and PSK

IKE version: IKEv2 is preferred for better stability and performance. if your remote side only supports IKEv1, you can use that.
Encryption and Integrity: choose AES-256 or AES-128 if you want more CPU headroom and SHA-256.
DH group: Group 14 2048-bit is a solid default.
Pre-shared key: enter a strong, unique key that you’ll store securely.

Phase 2 and PFS

Local/Remote proposals: select AES-256 or AES-128 with SHA-256 for Phase 2 SA.
Perfect Forward Secrecy PFS: enable PFS with a suitable group e.g., Group 14 or 19.
Dead Peer Detection DPD: set a reasonable timeout e.g., 30 seconds to keep the tunnel alive and detect dropouts quickly.

NAT traversal and firewall rules

Ensure NAT-T is enabled so IPsec can traverse NAT devices if needed.
Create firewall rules to allow ESP protocol 50, AH protocol 51 optional, UDP ports 500 and 4500, and IPsec traffic to the tunnel endpoints.
If you have any VPN-specific zones, isolate VPN traffic with appropriate firewall rules to avoid leaking or exposing LAN devices.

Apply and test

Save the configuration and apply changes.
Test the tunnel by pinging a device on the remote LAN from a device on your LAN.
Verify the tunnel status in the EdgeRouter UI. look for a “UP” or “Active” state and check the security association SA details.

Troubleshooting tips

If the tunnel won’t come up, verify PSK mismatches, keep-alive settings, and the exact LAN CIDRs on both sides.
Check logs for negotiation errors, mismatched proposals, or NAT issues.
Confirm both sides’ firewall rules allow the necessary traffic. sometimes a missing UDP 500/4500 or ESP block is the culprit.

Notes:

EdgeRouter X’s performance will depend on encryption settings and remote side capabilities. If you experience slow throughput, consider reducing the chosen encryption level slightly e.g., AES-128 or disabling extra features that add overhead during VPN negotiation.

OpenVPN Server on EdgeRouter X when supported

If your firmware supports OpenVPN server, here’s a practical workflow. If your firmware doesn’t support a stable OpenVPN server, skip to the WireGuard section or use IPsec for site-to-site.

Create the OpenVPN server

In EdgeOS, navigate to VPN > OpenVPN and choose Add OpenVPN Server.
Server mode: tun for remote access or bridge mode less common on EdgeRouter X for simple setups.
Address pool: define a small VPN client network e.g., 10.8.0.0/24.
DNS servers: push a local DNS or a public DNS 1.1.1.1, etc..

Generate keys and certificates

Create a simple certificate authority and server certificate if your OpenVPN implementation requires it, or use pre-shared keys if supported.
Add client profiles and certificates for remote users.

Client configurations

Export or copy the OpenVPN client configuration .ovpn or create per-user profiles.
Provide users with the necessary certificates or keys and the server’s public IP/host.

Firewall and NAT

Allow UDP 1194 default for OpenVPN, or your configured port on the WAN.
Create firewall rules to restrict VPN client traffic to the VPN subnet or required internal subnets.

Testing

Connect a client from an external network using the .ovpn profile.
Verify tunnel status and test access to internal resources.

Performance caveats

OpenVPN is versatile but can be CPU-intensive on EdgeRouter X at higher client counts. For many home setups, IPsec remains smoother if you only need site-to-site or a few remote clients.

WireGuard-style setup on EdgeRouter X

WireGuard offers excellent performance and simpler key management. EdgeRouter X support depends on firmware and community tooling, but you can often find a WireGuard option in newer EdgeOS builds or via community integrations.

Enable WireGuard if your firmware supports it

Access EdgeOS and look for WireGuard in the VPN or Interfaces area.
Create a new WireGuard interface e.g., wg0 with a private key and assigned IP e.g., 10.200.0.1/24.

Configure peers

Add peers with their public keys and allowed IPs e.g., 10.200.0.2/32 for a remote peer.
Set a recommended listen port 51820 by default and keep alive.

Firewall and routing

Add NAT rules to allow WireGuard traffic to reach your LAN.
Add firewall rules to isolate VPN traffic or allow access to specific subnets only.

Client configuration

Distribute a per-client public key and endpoint, then configure clients with their private keys and allowed IPs for laptops, phones, etc..

Testing and performance

Test connectivity across the tunnel. WireGuard tends to be faster and more reliable on modest hardware than OpenVPN.

Note: If your EdgeRouter X firmware doesn’t include native WireGuard support, you can explore community packages or compatibility layers. Always verify firmware compatibility and security implications before deploying.

Client-side tips: making VPN work smoothly for users

Choose a consistent DNS setup. When clients connect through VPN, you can push DNS settings e.g., your local DNS or a privacy-friendly DNS. This helps prevent DNS leaks and improves name resolution within the VPN.
Split tunneling vs full tunneling. Decide if you want all traffic to go through the VPN or only traffic destined for the remote network. Splitting traffic reduces CPU load on EdgeRouter X and can improve local browsing speed.
Use strong credentials. If you’re using PSKs, ensure they’re long and random. If you’re using certificates, protect the private keys and store them securely.
Regular updates. Keep EdgeOS and any VPN components up to date to take advantage of security fixes and performance improvements.

Performance and security: practical tips

Tune MTU. VPN tunnels add overhead. If you’re seeing slow performance, try lowering MTU by a few bytes to avoid fragmentation, which can hurt throughput.
Choose appropriate cipher suites. AES-256 is very secure, but in tight CPU scenarios AES-128 with SHA-256 can yield a noticeable performance gain with minimal security impact.
Enable DPDP dead peer detection to quickly notice dead links and re‑establish tunnels without manual intervention.
Monitor tunnel uptime. Set up simple monitoring pings, status checks to alert you if a tunnel goes down, so you can react quickly.

Real-world deployment ideas

Remote access to a home lab: a single EdgeRouter X provides remote access for a handful of devices while keeping everything segmented from the main LAN.
Small office site-to-site: connect your office with a satellite or another site, using IPsec for strong, stable encryption and performance comparable to a bigger router.
Hybrid VPN strategy: use IPsec for site-to-site links and WireGuard/OpenVPN for remote workers who need portable access. This gives you the best of both worlds.

Troubleshooting common VPN issues on EdgeRouter X

Tunnel won’t establish: double-check the remote peer address, PSK, and the IKE/Phase 2 proposals. Mismatched settings are the usual culprit.
Traffic not routing through VPN: confirm your firewall rules, NAT settings, and correct routing tables. Ensure that the VPN subnet and LAN subnets don’t overlap with remote networks.
Intermittent drops: check keep-alive, DPD, and MTU. You might need to tune DPD times or disable fragmentation by adjusting MTU.
Client connectivity problems: verify client config, including server address, port, and authentication method. Confirm client-side firewall or antivirus isn’t blocking VPN traffic.

Security best practices for EdgeRouter X VPNs

Use strong, unique pre-shared keys or, better yet, certificates for IPsec when possible.
Limit VPN access to only the networks that need it. Apply least-privilege rules in your firewall for VPN clients.
Regularly review and rotate credentials.
Disable unnecessary services on EdgeRouter X when VPN is in use to reduce attack surface.
Maintain a robust logging and alerting setup so you can spot unauthorized access attempts early.

Testing and verification: how to confirm the VPN is doing its job

Ping tests: from a device on your LAN, ping a host on the remote network. If you get responses with low latency, the tunnel is likely up.
Traceroute: trace to a remote subnet resource to ensure traffic is flowing through the VPN tunnel rather than the public Internet.
DNS checks: verify that DNS queries resolve as expected when connected to VPN to avoid leaks or misdirection.
VPN status page: use EdgeRouter X’s UI to monitor tunnel status, traffic, and SA details. Regularly review the tunnel’s health.
