Who the TP-Link ER8411 is for

Enterprise / multi-branch HQ pushing line-rate WireGuard. The ER8411 sits in TP-Link's Omada ER family — alongside other models that share the same firmware UI and configuration patterns but differ in CPU, throughput, and peer caps.

Setting up WireGuard on the ER8411

The six steps below match what the dashboard's vendor-template picker generates for the ER8411:

  1. Confirm firmware. Log in to the admin interface (typically http://192.168.0.1) and verify the installed firmware is ER8411_v1_1.4.0 (2024) or later. Update via Advanced → System → Firmware Upgrade if needed.
  2. Open the WireGuard page. Navigate to VPN → WireGuard → Tunnel List → Add Tunnel (Omada Controller-managed).
  3. Create a tunnel. Click Add. Generate a keypair. Set Listen Port to 51820. Set Tunnel IP to 10.100.0.1/24 for a hub or 10.100.0.2/32 for a spoke.
  4. Add a peer. Paste the remote public key. Set Allowed IPs to the remote tunnel /32 plus the remote LAN subnet. Set Endpoint Host and Endpoint Port if the remote has a stable public address. Persistent Keepalive: 21 if behind NAT.
  5. Enable and save. Toggle Enable and Save.
  6. Verify. The peer row should show a recent handshake timestamp within seconds of the remote side being configured.

ER8411-specific gotchas

  • Rackmount form factor — typical install is the central HQ, not a branch.
  • Saturates 1 Gbps WAN with WireGuard, leaves headroom for IPsec or OpenVPN concurrent if needed.
  • Omada Controller (self-hosted or cloud) is essentially required for the scale this hardware targets.

What changes at multi-branch scale

The ER8411 handles 1-5 sites cleanly. Past that, the configuration burden grows quadratically — five sites in a full mesh = ten peer relationships, each configured on both ends. The practical pattern past 3 sites is hub-and-spoke (every branch peers with one central router) plus a managed mesh layer that generates the per-router peer lists. MeshWG generates paste-ready configuration in the exact format the TP-Link UI accepts, including for the ER8411 specifically.

Frequently asked questions

Does the TP-Link ER8411 support WireGuard?

Yes, on firmware ER8411_v1_1.4.0 (2024) or later. The ER8411 runs on 2 GHz quad-core ARM and achieves 1.5+ Gbps single tunnel on a single WireGuard tunnel. WireGuard is configured under VPN → WireGuard → Tunnel List → Add Tunnel (Omada Controller-managed) in the admin interface, with up to 50 peers per tunnel on current firmware.

How fast is WireGuard on the TP-Link ER8411?

1.5+ Gbps single tunnel single-tunnel on the stock firmware, measured iperf3 over a stable LAN. The ER8411's 2 GHz quad-core ARM runs WireGuard without hardware acceleration, so the CPU is the binding constraint. For typical Indian SMB fibre uplinks (100-300 Mbps) the router is well above the WAN limit.

What is the firmware version with WireGuard on the TP-Link ER8411?

Firmware ER8411_v1_1.4.0 (2024) is the minimum that includes WireGuard. Confirm by visiting Advanced → System → Firmware Upgrade in the admin interface; if your installed version is below this floor, update via the same page first. Most ER8411 units shipped after the firmware floor date arrive with WireGuard available out of the box.

How do I find WireGuard in the TP-Link ER8411 admin UI?

VPN → WireGuard → Tunnel List → Add Tunnel (Omada Controller-managed). If the option isn't visible, the most likely cause is firmware below ER8411_v1_1.4.0 (2024) — update first, then revisit. On Deco devices specifically, the WireGuard configuration lives in the Deco mobile app, not the web admin.

How many WireGuard peers can the TP-Link ER8411 support?

50 peers per tunnel on current firmware. This is the cap on devices connecting into this router as a WireGuard server (or peers this router has configured outbound). For deployments larger than this cap, the practical pattern is hub-and-spoke with a higher-capacity device (Omada ER7206 or ER8411) at HQ.

Can I run WireGuard between the TP-Link ER8411 and a different router brand?

Yes. WireGuard is the same protocol on every implementation — your ER8411 interoperates with WireGuard on MikroTik, OpenWrt, OPNsense, pfSense, Ubiquiti, Asus, GL.iNet, and the official Linux/Mac/Windows/iOS/Android clients. Configuration is the same set of fields (public key, endpoint, allowed IPs); only the UI for entering them differs per vendor.
