I see alot of posts recently of people not being able to or not knowing how to connect to a VPN. This will work for PC and Console.
Step 1:
head over to your Hybrid VPN Tab and add device.
Step 2:
add service (if on console make sure to set device type to computer in the device manager tab) and enter these ports:
UDP source: start 1 end 65535 destination start 3074 end 3074
also add the TCP source: start 1 end 65535 destination start 443 end 443
Step 3:
Enable VPN setup, click on VPN setup and guide to Advanced. Enter your VPN details such as Username, Pasword and the text inside your config file.
Step 4:
Head over to your game (in this case Cod MW2) and head over to net work info to check if the VPN works. I live in Europe not India as the game states, we can conclude it works.
