Orbi AX5400 Tri-Band WiFi 6 Router(RBR760) & OpenVPN

If you are having trouble getting the VPN to work on Windows, modify the the config file to use 'dev tun' on line two and change the port number to 12973 (on the remote line 5) or match the port setting in the admin console.  You can also replace ciphers AES-128-CBC to data-ciphers-fallback AES-128-CBCto remove an warning. I have used OpenVPN client 2.5.8 and 2.6.0 and it works.  The mobile phone config files also work on my iPad and iPhone.

The client would act like it was connecting but never tunnel to the network so you could not rdp or open any local files.

I spend days with support trying to figure this out and they struggled to find the solution.  Luckily my own windows admin teammate knew what to do!
