Body
Why you’d want a VPN on the EdgeRouter X
The EdgeRouter X sits between your local network and the wider internet, acting as the gateway for all devices on your LAN. Adding a VPN here has several advantages:
- Centralized VPN management: run a single VPN hub rather than configuring VPN on every device.
- Privacy and remote access: securely connect to your home network from anywhere, or link multiple sites together for a private corporate-like network.
- Performance control: you can tune encryption settings and routing policies to balance speed and security on your own terms.
- Compatibility with other devices: you can route traffic from networked devices like cameras, NAS, home servers through the VPN without installing VPN apps on each gadget.
That said, the ER-X isn’t a powerhouse firewall/router, so you’ll want to manage expectations about VPN throughput. You’ll often see OpenVPN performance in the tens to hundreds of Mbps range, depending on cipher, tunnel type, and CPU load. IPsec tends to be more efficient, but still benefits from optimized settings and fewer simultaneous tunnels.
What VPN protocols does EdgeRouter X support?
- IPsec IKEv2/IKEv1 with OpenVPN-style options: great for site-to-site and remote access with strong security and broad client support.
- OpenVPN: widely supported and flexible, but typically more CPU-intensive on older hardware like the ER-X.
- L2TP over IPsec: a convenient option for devices that don’t support OpenVPN, though L2TP/IPsec can be slower and sometimes harder to configure securely.
- WireGuard: not built into EdgeOS by default on many ER-X units, though there are ways to experiment with packages or newer EdgeOS builds. expect caveats and potential instability on older firmware.
In practice, most home users leaning on legacy devices like the ER-X will start with IPsec for site-to-site and remote access, then consider OpenVPN if they need compatibility with devices that don’t play nicely with IPsec. If you’re chasing speed and a modern protocol, keep an eye on EdgeOS updates for any WireGuard options.
Preparing your EdgeRouter X for VPN
Before you configure anything, a quick prep checklist helps avoid a lot of headaches:
- Update EdgeOS to the latest stable firmware your device supports. This ensures bugs are fixed and VPN features are current.
- Note your public IP or set up a static WAN IP/dynamic DNS if your connection isn’t fixed.
- Decide your network topology: will VPN be site-to-site two networks connected or remote access individual devices connect to your home router?
- Back up your current configuration in case you need to roll back.
- Choose your VLANs and firewall zones carefully to avoid exposing VPN endpoints to insecure networks.
CLI vs GUI: EdgeRouter OS offers both. The GUI is friendlier for quick setups, while the CLI gives you precise control and is great for repeating complex configurations. If you’re new, start in the GUI. for repeated deployments, keep a CLI template. Big ip client edge for secure remote access and VPN setup guide
Setting up IPsec site-to-site VPN on EdgeRouter X
IPsec site-to-site is the most common way to connect two networks securely over the internet. Here’s a practical outline you can adapt.
Key concepts:
- Local and remote networks: the two subnets you want to interconnect e.g., 192.168.1.0/24 and 192.168.2.0/24.
- Phase 1 IKE and Phase 2 IPsec proposals: define encryption and authentication methods.
- Pre-shared key PSK or certificates for authentication.
- Phase 2 tunnel parameters and traffic selectors local and remote prefixes.
- Firewall and NAT rules to ensure traffic flows through the VPN tunnel.
High-level CLI steps simplified:
- Enable VPN interfaces and IPsec
- Create IKE/ESP proposals
- Define the remote peer public IP of the other site
- Set the local and remote networks
- Configure firewall rules to allow VPN traffic
- Commit and save
Example placeholders. adapt to your IPs and keys:
configure
set vpn ipsec ipsec-interfaces interface eth0
set vpn ipsec ike-group IKE-GRP family inet authentication mode pre-shared-secret
set vpn ipsec ike-group IKE-GRP key-exchange ikev2
set vpn ipsec ike-group IKE-GRP proposal 1 encryption aes128
set vpn ipsec ike-group IKE-GRP proposal 1 hash sha256
set vpn ipsec ike-group IKE-GRP proposal 1 dh-group 14
set vpn ipsec site-to-site peer 203.0.113.10 authentication mode pre-shared-secret
set vpn ipsec site-to-site peer 203.0.113.10 authentication pre-shared-secret ‘yourpsk’
set vpn ipsec site-to-site peer 203.0.113.10 ike-group IKE-GRP
set vpn ipsec site-to-site peer 203.0.113.10 tunnel 1 local prefix 192.168.1.0/24
set vpn ipsec site-to-site peer 203.0.113.10 tunnel 1 remote prefix 192.168.2.0/24
commit
save
exit
GUI steps for those who prefer clicking: Is microsoft edge secure network vpn free
- Go to VPN > IPsec VPN > Add VPN
- Enter the remote peer’s public IP, PSK, and a friendly name
- Set IKE version typically IKEv2 for modern setups
- Define Phase 1 and Phase 2 proposals AES-128 or AES-256, SHA-1/256, DH group
- Configure local and remote networks
- Create firewall rules to allow IPsec traffic UDP 500, UDP 4500, and ESP protocol 50 if needed
- Apply and test with a ping to the remote network or a traceroute
Tips for a smooth IPsec site-to-site:
- Use a stable PSK and store it securely. rotate it periodically.
- Keep the tunnel from flapping by tuning dead-peer-detection if supported and reducing aggressive rekey intervals.
- If you have dynamic IPs on one side, consider a dynamic DNS setup on the ER-X and dynamic updates on the remote gateway.
Setting up OpenVPN on EdgeRouter X
OpenVPN is a universal option for remote access, especially for clients that don’t support IPsec easily. It’s more CPU-intensive on devices like ER-X, but it’s flexible and easy for end users to connect.
Key notes:
- OpenVPN on EdgeRouter OS usually runs on the edge device via a tun interface.
- You’ll create a VPN server on the ER-X and distribute client profiles .ovpn to users.
- Performance depends heavily on CPU. you may want AES-128-CBC or AES-256-CBC depending on your clients and hardware.
High-level steps:
- Generate server and client certificates you can use EasyRSA or built-in EdgeOS tooling in newer builds
- Configure the OpenVPN server in EdgeRouter OS
- Create client profiles and distribute
- Open firewall ports for OpenVPN UDP 1194 by default, but you can customize
- Test connections from a remote device
CLI example simplified:
set interfaces openvpn vtun0 mode server
set interfaces openvpn vtun0 server …
set vpn openvpn server proto udp
set vpn openvpn server port 1194
set vpn openvpn server local-address 10.8.0.1
set vpn openvpn server subnet 10.8.0.0/24 Turbo vpn alternative: the ultimate guide to top VPN options for speed, privacy, streaming, and value in 2025
GUI steps:
- Go to VPN > OpenVPN if available > Add/OpenVPN Server
- Upload or generate server certificate, define port, protocol, and tunnel network
- Add client export or profile. distribute to users
- Create firewall rules to allow UDP 1194 or your chosen port
Performance considerations:
- OpenVPN is slower on the ER-X than IPsec, especially with default cipher choices. If you must use OpenVPN for compatibility, consider lighter ciphers AES-128-CBC and smaller TLS keys to squeeze more headroom.
- You can reduce CPU load by turning on hardware offloading if your model and firmware support it, and by disabling unnecessary services on the router.
Setting up L2TP over IPsec on EdgeRouter X
L2TP over IPsec can be a friendlier option for devices with built-in L2TP clients many mobile devices and some desktops. It’s simpler for clients to configure but can be slower and, in some setups, less secure if not properly tuned.
- Enable L2TP over IPsec on the ER-X
- Configure a shared secret and assign the VPN pool
- Add firewall rules to allow L2TP/IPsec traffic
- Distribute client settings to devices
CLI example very simplified:
set vpn l2tp enable
set vpn l2tp remote-ips 10.8.0.0/24
set vpn l2tp remote-access authentication mode local
set vpn l2tp remote-access local-users username vpnuser password ‘yourpassword’
- VPN > L2TP over IPsec > Add VPN
- Set shared secret, pool of IPs, and user accounts
- Save and test with a client device
Optimizing VPN performance on EdgeRouter X
- Choose the right protocol for your needs: IPsec for generally better throughput and efficiency. OpenVPN when you need broader client compatibility.
- Tweak MTU and MSS values to prevent fragmentation. Typically, a lower MTU on VPN tunnels e.g., 1400 helps if you have varied networks.
- Use AES-128-GCM or AES-256-GCM if your EdgeOS version supports it. they’re faster and more secure than CBC modes in many scenarios.
- Enable connection tracking and ensure firewall rules are streamlined. overly complex rules can bottleneck performance.
- Avoid double-NAT: if you’re connecting to a VPN that sits behind NAT, consider port-forwarding or using a bridge in your topology to minimize translation overhead.
- Monitor CPU load during VPN sessions. If you’re seeing sustained high usage, consider reducing the number of concurrent tunnels or moving to a more powerful router for heavy remote work.
- For OpenVPN users, enable compression only if you know your data is compressible. compression can backfire with certain traffic patterns and cause vulnerabilities in some configurations.
Security considerations and common pitfalls
- Keep EdgeOS firmware up to date. VPN bugs and cryptographic vulnerabilities get patched in new releases.
- Use strong authentication. Prefer IKEv2 with strong PSKs or certificates over older, weaker methods.
- Disable unused services. The less you expose to the internet, the better.
- Regularly back up VPN configurations. A quick restore beats scrambling through a broken setup after a power outage or firmware update.
- Be careful with default passwords and admin accounts. Change them to strong, unique ones and consider disabling remote admin access unless you need it.
- DNS leaks: ensure the VPN tunnel handles DNS requests properly and consider forcing DNS through the VPN for privacy.
- Split tunneling caveat: if you enable split tunneling, be mindful of privacy and security implications. only route sensitive traffic through the VPN if that’s your goal.
Advanced tips: DNS, split tunneling, and VPN passthrough
- DNS configuration: point VPN clients to a trusted DNS server and consider a DNS leak test after connecting to the VPN.
- Split tunneling: decide whether to route all traffic through the VPN or only specific subnets. Split tunneling improves speed but can reduce privacy.
- VPN passthrough: ensure your firewall rules permit VPN traffic in both directions to avoid leaks or blocked connections.
Example policy suggestion: Best vpn edge extension: the ultimate guide to Edge browser VPN extensions, privacy, streaming, and performance
- Route only traffic destined for the remote network through the VPN. all other traffic goes through your normal WAN connection.
- Test with traceroute/dig/nslookup to verify DNS privacy and path integrity.
Real-world scenarios and use cases
- Small office connecting to a remote site: IPsec site-to-site VPN bridges two LANs, letting printers, file servers, and devices communicate securely as if they were on the same network.
- Remote workers: OpenVPN on EdgeRouter X enables employees to securely access internal resources from home or on the road without installing a VPN on every device.
- Privacy-conscious home lab: Run a VPN to route traffic from your test devices through your home VPN for added privacy while testing services.
Future-proofing: WireGuard and EdgeOS updates
- WireGuard is the next big thing in VPN performance. many users want native WireGuard support on EdgeRouter X. Depending on firmware, you may find experimental packages or supported builds that enable WireGuard, but stability can vary. If you’re aiming for the best possible speed and modern protocol, stay updated with Ubiquiti’s EdgeOS release notes and community discussions to see when/if WireGuard becomes a first-class option on ER-X.
- Watch for EdgeOS updates that improve OpenVPN performance or add native WireGuard integration. As EdgeOS evolves, you’ll see more options and better support for newer VPN protocols without overtaxing the ER-X.
Troubleshooting common VPN issues
- VPN tunnel keeps dropping: check for dynamic IP changes on either end, keep-alive settings or rekey intervals, and firewall rules. A short rekey interval can help if devices frequently lose reachability.
- Clients can’t connect: verify PSK or certificate validity, ensure correct remote IP/hostname, and confirm port exposure on the WAN side.
- Slow VPN performance: test with IPsec vs. OpenVPN to compare. ensure you’re not hitting device CPU limits. reduce encryption complexity if possible. adjust MTU/MSS accordingly.
- DNS leaks: verify VPN DNS settings and consider forcing DNS resolution through the VPN tunnel.
- Connectivity after firmware updates: back up configurations, note any interface name changes, and re-apply VPN settings. Some firmware updates reset or alter VPN templates. you may need to re-toggle certain features.
Real-world test results and benchmarks illustrative
- IPsec site-to-site on ER-X AES-128-GCM, no multi-hop: typical real-world throughput ranges from 300 Mbps to 700 Mbps under ideal conditions, but in many home setups you’ll see lower figures due to network overhead, WAN connection quality, and client hardware.
- OpenVPN remote access on ER-X: common in the 60–200 Mbps range for AES-128-CBC, depending on CPU load and packet characteristics. enabling AES-256 and using modern TLS ciphers can further reduce throughput but improve security.
- L2TP/IPsec: generally between IPsec and OpenVPN in terms of throughput, with the caveat that client devices and network factors can swing results.
Remember, these are representative numbers. Your actual results depend on your ISP, device load, tunnel configuration, and encryption choices. The key is to optimize for your specific use case: remote access ease, site-to-site reliability, or a balance of both.
