Telus Router opening ports and port fowarding

Hardware answer is neither.

The only hardware i have is a white cylindrical one, that states its model number is the B20A. The I/Os do not look anything like the picture shown. I have used the same unit in both my rental suites. Also I suspect it is more than "merely a wireless access point" as I don't use it for wireless access. It has all its i/o at the bottom of the unit, one for power, one is for a coaxial cable, one is ethernet input and two ethernet outputs. My hardware setup is one ethernet cable connects from the wall to the unit, and I have two wired connections to my two computers.

Basic setup

server PC - wired connection has a vpn which is currently off to limit possible sources of problems while troubleshooting. In the past for a year it worked with the VPN up/on. This can connect to the internet currently.

Main PC - wired connection has a vpn which is on. Can not connect to the server pc. can connect to the internet.

My understanding is that in this configuration I should be able to test and connect with my servers. As all my connection with the main PC are outbound with the VPN IP address and coming back inbound to the actual IP address and that via port forwarding the traffic is directed to the server PC.

As for teamspeak I can't speak to your points because It was working for about a year and when I moved in march that is when it stopped but so did my other server. In fact because of how the TS client is separate from the TS server, it is designed to be able to use the client and the server on the same PC. At least this is what I was told on the TS forums. In any case my main pc is the one trying to connect  to my server pc and a VPN is being used.

I don't mean to sound argumentative if that is how it comes across, I am just telling you the facts as I understand them. Teamspeak worked with telus and all I have is the B20A. It can and is being used outside merely are wireless hub. I hate wireless so I don't use it and the B20A is allowed me to use wired connections for a year now. I do appreciate your help and I am sorry this isn't textbook.
