It’s not the slam-dunk gaming router, but it shines in flexibility, custom routing, and price-to-performance ratio. It uses EdgeOS, a Linux-based firmware, which gives you control over routing tables, firewall rules, and VPN integration that consumer-grade “router-in-a-box” devices often hide behind a simple push-button interface. Why run a VPN directly from EdgeRouter X? - Control: You manage the VPN gateway at the network edge, not rely on each device. - Compatibility: OpenVPN and IPsec are widely supported by VPN providers and enterprise-grade servers alike. - Privacy and consistency: All devices on your LAN can be forced to use the VPN by default, not just your PCs or phones. - Cost efficiency: A single device can cover a lot of devices without needing multiple paid apps or subscriptions on each device. On the flip side, EdgeRouter X is relatively modest in raw crypto horsepower compared with pricier routers. VPN throughput will be CPU-bound, so expect lower speeds once encryption is active. The upside is predictable NAT performance and a lot of power for a small device, especially if you don’t push it to the max with heavy simultaneous VPN sessions. When you’re weighing options, ask yourself: - Do you need full-network VPN coverage for all devices, or just specific devices? - Is a site-to-site link with a remote office or a VPS the goal, or are you just protecting a home network? - How fast is your internet connection, and what VPN protocol does your provider support best on EdgeRouter X? VPN options on EdgeRouter X EdgeRouter X supports several VPN setups. Here’s a practical breakdown of what to use and when. # OpenVPN client OpenVPN is the most widely supported option on EdgeRouter X. It’s flexible, supports user authentication, and works with almost all VPN providers that supply OpenVPN config files including NordVPN, ProtonVPN, and many others. OpenVPN generally provides robust security and compatibility, but it comes with some CPU overhead, which reduces throughput on budget routers like the EdgeRouter X. - Best for: Full-network VPN coverage, easy integration with most providers, strong documentation and community support. - Pros: Broad compatibility, mature client implementation, strong community examples. - Cons: CPU overhead on EdgeRouter X reduces raw throughput. needs careful routing rules for split tunneling. Key notes: - You’ll typically import a .ovpn file or copy the necessary server address, port, and certificate data into EdgeOS OpenVPN client settings. - You can implement a “kill switch” by forcing LAN traffic to go only through the VPN interface and blocking leaks if the VPN drops. - To enable DNS privacy, point your LAN clients to VPN-provided DNS or configure a DNS over VPN option within the OpenVPN setup. # IPsec site-to-site IPsec is ideal for a site-to-site connection for example, between your home network and a remote office or a dedicated VPN server at a VPS. It’s highly compatible with many firewalls and can be very fast when tuned correctly. In EdgeRouter X, you’ll typically configure Phase 1/2 IKE and IPsec SA settings and then create a tunnel between your EdgeRouter X and the remote gateway. - Best for: Secure network-to-network connections, corporate-style VPN topologies, or connecting to a remote server you control. - Pros: Excellent security with modern ciphers, efficient for sustained tunnels, good for fixed-site links. - Cons: More complex to configure for beginners. some provider setups require precise routing policies. # L2TP over IPsec L2TP over IPsec is a popular consumer VPN method because it’s supported by many clients and devices. On EdgeRouter X, L2TP over IPsec can be used for remote access or as a simpler alternative to OpenVPN for certain VPN providers. It’s generally easier to set up on many routers but can be less efficient than OpenVPN in some scenarios. - Best for: Quick remote access setups with providers that publish L2TP-PSK profiles. - Pros: Simple client compatibility, easy to test. - Cons: Slightly weaker security in some configurations. slower performance on CPU-constrained devices. # WireGuard on EdgeRouter X status and caveats WireGuard is fast and modern, but as of late 2024, WireGuard support on EdgeRouter X depends on firmware versions and community efforts. Official, native WireGuard support on EdgeOS is not as universal as OpenVPN or IPsec, and some builds require manual kernel/module work or workarounds. If you absolutely need WireGuard, verify compatibility with your EdgeOS version or consider a dedicated WireGuard-capable router or running it on a separate device in your network. - Best for: Speed-focused networks where you can confirm a supported build. - Pros: Very fast, simple configuration in many cases, strong security with minimal code. - Cons: Not officially guaranteed on all EdgeRouter X firmware versions. setup complexity varies. Performance and real-world expectations - Without VPN: EdgeRouter X can route at or near 1 Gbps in typical home scenarios with modest firewall rules. - With OpenVPN: Real-world throughput often lands in the hundreds of Mbps range, heavily depending on CPU load and encryption settings. Don’t expect the full line speed when active VPN is on. - With IPsec: VPN performance is usually better than OpenVPN on modest hardware, but it still depends on cipher choice, MTU, and remote gateway tuning. - Split tunneling: If you route only some subnets through VPN, you’ll maintain higher local network speed while protecting sensitive traffic. - Kill switch and DNS: Always enable a DNS leak prevention measure and a kill switch to avoid IP leaks when VPN drops. Step-by-step guide: OpenVPN client on EdgeRouter X This walkthrough uses the EdgeRouter Web UI EdgeOS. If you prefer CLI, you can translate these steps into the CLI equivalents, but the UI method is usually quicker for most home setups. Step 1: Prepare your OpenVPN config - Download the OpenVPN client configuration .ovpn from your VPN provider. - For NordVPN or similar, you may receive separate certificate/key files or embedded certs inside the .ovpn file. - Make a note of your VPN username and password if required some providers use certificate-based auth instead. Step 2: Access EdgeRouter X Web UI - Open your browser and go to the EdgeRouter’s IP address often 192.168.1.1 or 192.168.0.1. - Log in with admin credentials. Step 3: Create the OpenVPN client - Navigate to VPN > OpenVPN. - Add a new Client type: Client or Import, depending on UI version. - If your UI supports importing .ovpn directly, choose Import and upload the .ovpn file. - If you must copy-paste, enter: - Server address and port from your .ovpn - TLS/SSL configuration as provided CA cert, client cert if needed - Authentication method username/password or certificate - Certificate/key data if separate files are provided Step 4: Configure the VPN interface - EdgeRouter will create a tun0 or similar interface once the client starts. - Ensure the VPN interface is enabled and set as the default route when VPN is up. Step 5: Route LAN traffic through the VPN full-tunnel - Create a policy or route that sends LAN traffic through the VPN interface tun0 by default. - Disable direct internet access for LAN devices if you want all traffic to go through the VPN. - If you want split tunneling, specify only selected subnets to route via VPN e.g., 192.168.1.0/24 and leave your LAN-only resources direct. Step 6: DNS and kill switch - Point DNS to a provider’s DNS over VPN or to a public DNS that supports DoH/DoT if you’re comfortable with that setup. - Implement a simple kill switch by blocking non-VPN traffic when the VPN interface is down this is usually a firewall rule that drops traffic from LAN if tun0 is down. Step 7: Test - Connect a client device to the EdgeRouter LAN. - Visit a site that shows public IP like whatismyip.com to confirm the IP matches the VPN exit node. - Check for DNS leaks by testing with dnsleaktest.com or similar. - Disconnect VPN to verify traffic stops routing and then reconnect to confirm the VPN comes back up properly. Step 8: Fine-tuning and security - Confirm MTU is optimized to avoid packet fragmentation try 1400-1500 as a starting point. - Consider enabling DNSSEC or using a VPN provider’s DNS with DNS leak protection. - Document your VPN hostname, account, and any backup VPN profiles for quick recovery. Tips: - Start with a simple setup and gradually add policies. It’s easy to break connectivity if routes aren’t aligned. - If your ISP blocks or throttles VPN traffic, switch to a provider that offers obfuscated servers or alternate ports. - For better performance, choose a VPN server geographically close to you and try a fewer hops path when possible. Step-by-step guide: IPsec site-to-site on EdgeRouter X Step 1: Plan the tunnel - Decide which networks will participate e.g., 192.168.1.0/24 at home and 192.168.2.0/24 at the remote site. - Gather the remote gateway IP, PSK, and IKE/ESP cipher preferences. Step 2: EdgeRouter X setup - In EdgeOS, go to VPN > IPsec and create a new Site-to-Site VPN. - Define the local network LAN and remote network the network at the other end. - Configure IKE Phase 1 encryption, hash, DH group and Phase 2 encryption, PFS if needed, lifetime. - Enter the remote gateway IP and pre-shared key PSK. Step 3: Firewall and NAT - Create firewall rules to allow IPsec traffic ESP, AH if used, UDP 500/4500, etc.. - Ensure NAT is disabled for the tunnel or appropriately configured to allow remote subnets to appear correct at the other end. Step 4: Test and monitor - Bring the tunnel up and verify with a ping across the remote network. - Use traceroute or mtr to diagnose hops if traffic doesn’t route as expected. - Ensure that the VPN remains up after reboots and that keep-alive settings are in place. Step 5: Security hygiene - Rotate PSK periodically and restrict remote gateway IPs to known addresses. - Consider a dead-peer detection DPD setting for quick failover. Performance tips for VPN on EdgeRouter X - Choose OpenVPN with AES-256-GCM or AES-128-GCM if available. these tend to be faster on many CPUs than older ciphers. - If your router’s CPU struggles, reduce the VPN’s encryption strength or switch to IPsec where feasible. - Use a nearby VPN server to lower latency and improve throughput. - Avoid unnecessary firewall rules that inspect traffic deeply. keep rules tight and efficient. - Split tunneling can dramatically improve performance by keeping local traffic off the VPN path. - Keep firmware up to date. security patches and performance improvements are common in EdgeOS updates. DNS, kill switch, and security best practices - DNS leaks are a common issue when routing traffic through a VPN. Ensure your EdgeRouter UA uses VPN-provided DNS servers or a trusted DoT/ DoH setup. - Implement a robust kill switch to stop traffic if the VPN drops. A simple approach is to drop LAN traffic when the VPN interface is down. - Regularly audit firewall rules to ensure there are no inadvertent open ports that bypass the VPN. - If you have a dynamic IP from your ISP, consider using a Dynamic DNS DDNS service to keep remote access stable. Split tunneling vs full tunnel - Full tunnel: All traffic from your LAN goes through the VPN. This is the simplest for a single VPN policy and can be easier to manage for everyone on the network. - Split tunneling: Only specific subnets or devices go through the VPN. This preserves full local network speed for non-VPN devices and is useful when you want only sensitive traffic to ride the VPN. Choosing between them depends on your goals and the VPN provider’s VPN server performance. Start with full-tunnel to confirm stability, then move to split if you need more speed or to avoid routing domestic traffic through the VPN. Troubleshooting quick-start - VPN tunnel won’t come up: double-check credentials, server address, and that the correct interface is selected. Look for logs in EdgeRouter UI under VPN > OpenVPN or VPN > IPsec. - DNS leaks: ensure VPN DNS is used by LAN clients. test with dnsleaktest.com. - Slow VPN speeds: switch to a nearby server, confirm MTU settings, and reduce cipher overhead if needed. - Connection drops: enable keep-alive settings in the VPN profile and consider a more stable server or provider with better uptime. - Split tunneling not working: verify route rules and ensure the VPN interface is correctly selected as the gateway for the target subnets. NordVPN and other providers: what works best on EdgeRouter X NordVPN and other mainstream providers typically publish OpenVPN configurations and IPsec profiles that work well with EdgeRouter X. If you want a quick-start experience with strong privacy features, NordVPN’s OpenVPN configuration is a solid option, especially when you leverage OpenVPN client mode on EdgeOS. For a balance of speed and security, IPsec site-to-site can be a better fit if you’re connecting to a remote office or dedicated VPS that you control. Pro tips: - Always download the latest .ovpn files and CA certificates from your VPN provider to ensure compatibility with EdgeOS. - If you’re new to VPNs, start with a provider that offers clear EdgeRouter/X-based tutorials or community guides to reduce troubleshooting time. - Evaluate if you need user-based authentication OpenVPN with username/password or certificate-based authentication. certificate-based setups can be more secure but slightly more complex.
