GL.iNet Brume 2 (GL-MT2500) VPN Security Gateway

The Brume 2 (GL-MT2500 / GL-MT2500A) is a small box that solves a big problem: secure remote access to your home or office network without paying for it in complexity. It is a lightweight, powerful VPN security gateway designed to host a VPN server at home or run SD-WAN (site-to-site) networking for small and medium-sized enterprises.

Performance is what sets it apart from a repurposed old router: 355 Mbps over WireGuard and 150 Mbps over OpenVPN, a 2.5 Gbps WAN port, 1 GB DDR4 memory and 8 GB eMMC storage — all drawing under 2.6 W in a 70 x 70 x 22 mm chassis. VPN cascading lets it run server and client at the same time, so you can reach local resources remotely while browsing through a commercial VPN.

It runs open-source OpenWrt 21.02 with thousands of ready-made plug-ins, comes with AdGuard Home for network-wide ad and tracker blocking, and supports 30+ VPN providers. Choose the GL-MT2500 in light ABS plastic for best value, or the GL-MT2500A in frosted aluminium alloy — they are functionally identical.

Frequently asked questions

What is the difference between GL-MT2500 and GL-MT2500A?

Only the housing: the MT2500 uses lightweight ABS plastic and the MT2500A a frosted aluminium alloy case. They are functionally identical — the price difference is purely the material.

Is it a Wi-Fi router?

No — the Brume 2 is a wired security gateway with a 2.5 Gbps WAN port and a gigabit LAN port. It sits between your network and the internet, handling VPN, ad blocking and encrypted DNS duties.

Can it run a VPN server and client at the same time?

Yes. VPN cascading lets it host a server (for remote access to your home network) while simultaneously running as a client to a commercial VPN, forwarding data between the two within the same device.

What can I use it for at a company?

Remote work and SD-WAN: staff at home reach internal resources over encrypted tunnels, and head office and branch offices can be joined into one virtual office with all internal communications protected by VPN encryption.

Does it block ads?

Yes — AdGuard Home is ready on the device, blocking ads, online trackers and age-restricted content for all client devices, with customisable DNS filters.
