Brume 2 router review with WireGuard, OpenVPN, Tor, and Adguard Home

Brume 2 review

We started the review of GL.inet GL-MT2500A security gateway, aka Brume 2, with an unboxing and teardown, and I’ve now had time to test the router in more detail so I’ll report my experience using the router with OpenVPN and WireGuard VPN, Tor, Adguard Home, and more. In a nutshell, it’s super easy to use, unless your ISP causes troubles, which it did in this case. Brume 2 connection and initial setup I connected the WAN port of the Brume 2 router to 3BB’s modem router (3BB is an ISP in Thailand), the LAN port to my laptop, and finally the USB-C power supply (power draws is 2.3 Watts at idle). Let’s now go to the dashboard using the default IP (192.168.8.1). This will take us through the configuration wizard to select the language and set up the admin password. I was then immediately greeted by an “Upgrade Reminder” and […]
