A few months older thread, but I was able to get OpenVPN on my Brume 2 to use TCP/443, but I did it manually after looking through this and other threads here. I successfully used TCP/443 during my trip to Europe to connect to the Brume 2 OpenVPN server from whatever network I was connected to including my cellular WiFi hotspot. and even from a cruise ship’s network.
- I replaced the 443 listen port parameters in the /etc/nginx/conf.d/gl.conf file from 443 to 4433 using SSH and the vi text editor.
- I rebooted, and after I rebooted I now to used https://192.168.8.1:4433 to connect to the SSL GUI.
- I changed the OpenVPN server to use Protocol TCP and Port 443.
- I started the OpenVPN and it started and is working on TCP/443.
I’m thinking about purchasing a new Flint 2 router, but I hope the procedure is the same if I do get it since the TCP/443 protocol doesn’t seem to be blocked anywhere that I’ve tried so far. And I hope that future firmware updates don’t overwrite this configuration and reset the gl.conf file back to the defaults.
