Description

Overview

The TP-Link ER605 is a gigabit VPN router built for small offices and businesses with more than one branch. It sits at the edge of the network as the gateway, connecting the office to the internet and linking branch offices over VPN. It is part of TP-Link’s Omada SDN family, so it can be managed alongside Omada access points and switches.

This is the v2 hardware, the current version. It has five Gigabit Ethernet ports: one dedicated Gigabit WAN port, two Gigabit WAN/LAN ports that can be set as either, and two Gigabit LAN ports. That gives it up to three WAN Ethernet connections at once, plus a USB 2.0 port for a 4G/3G modem as backup WAN.

Under the hood, the ER605 handles 150,000 concurrent sessions and 1,800 new sessions per second, with NAT throughput of 941.64 Mbps upload and 944.35 Mbps download on a static IP connection. On VPN it supports IPsec (20 tunnels), WireGuard (20), OpenVPN (16), L2TP (16) and PPTP (16), plus GRE and SD-WAN in controller mode. IPsec throughput is 250.94 Mbps and WireGuard runs at 82.62 Mbps, so encrypted links are fast enough for real work.

Key Benefits

The first benefit is uptime. Most small offices lose a working day when their single internet line goes down. The ER605 takes up to three WAN connections and balances the load between them, with link backup that moves traffic to a working line automatically when one fails.

The second benefit is that the VPN is built in, not bolted on. The ER605 handles IPsec, WireGuard, OpenVPN, L2TP and PPTP natively, with 20 IPsec and 20 WireGuard tunnels, so branch offices and remote staff are handled by the same device that routes the traffic.

The third benefit is centralised management. Adopted into an Omada controller — the app, a hardware controller like the OC200 or OC300, the software controller, or the cloud-based controller — the router, switches and access points are managed from one dashboard, with zero-touch provisioning for new sites. And the ER605 is quiet and cheap to run: a fanless steel box, 158 × 101 × 25 mm, drawing at most 7.94 W, with 4 kV surge protection.

Features and Advantages

Multi-WAN is the feature that defines this router. Up to three WAN Ethernet ports plus one USB WAN give four possible paths to the internet, with load balancing, link backup, and policy and static routing to send particular traffic down particular lines.

The firewall and security features are thorough for a router at this price: SPI firewall, DoS defence, IP-MAC binding, ARP inspection, IP, MAC and URL filtering, ACLs and a captive portal. IPTV is supported through IGMP v2/v3 proxy, and IPv6 is fully supported.

VPN is the other half of the story. IPsec runs at 250.94 Mbps and WireGuard at 82.62 Mbps — a large step up from the older v1, which managed only 41.5 Mbps on IPsec and had no WireGuard, no USB port and no SD-WAN. The router also works as a VPN client for up to 10 servers.

Management is flexible. Standalone, the web UI covers everything, with CLI, SNMP, syslog and port mirroring. Adopted into Omada, it gains cloud access and zero-touch provisioning. DPI throughput is 944 Mbps on TCP and 940 Mbps on UDP.

Ideal Users

The ER605 suits a small office that has outgrown a home router: a business with 10 to 50 people, a couple of internet lines, and a branch or two. The multi-WAN load balancing keeps the office online, the VPN joins the branches together, and Omada management keeps the whole thing under control from one place. It also suits a shop, a clinic, a school or a small hotel that cannot afford to lose internet.

It is a good fit for an Omada site. If the office already runs Omada access points, the ER605 is the gateway that completes the picture. What it does not suit is a home that only needs Wi-Fi and one internet line — it is a wired router with no wireless radios, so it always needs access points for Wi-Fi.

FAQs

Is the ER605 a Wi-Fi router?
No. It is a wired VPN router with no wireless radios. It needs access points for Wi-Fi, such as the TP-Link EAP655-Wall indoors or the TP-Link EAP225-Outdoor outside.

What is the difference between the ER605 v1 and v2?
The v2, sold here, has five Gigabit ports including a USB 2.0 port for a 4G/3G modem, 150,000 concurrent sessions, IPsec at 250.94 Mbps, WireGuard, SD-WAN and GRE. The older v1 had no USB port, 25,000 sessions and IPsec at 41.5 Mbps.

Can it keep my office online if the main internet line fails?
Yes. With up to three WAN Ethernet ports plus a USB WAN, you can set a second line or a 4G dongle as backup. Link backup moves traffic to the working line automatically.

How many VPN tunnels does it support?
IPsec 20, WireGuard 20, OpenVPN 16, L2TP 16 and PPTP 16, plus GRE and SD-WAN in controller mode.

Does it need an Omada controller to work?
No. It works standalone through its web interface. An Omada controller adds centralised management, cloud access and zero-touch provisioning.
