If you're actually using the university network, many universities block external games playing because of the bandwidth it uses.. And yep, if you don't have admin rights to their router/gateway, you can't change it.
Hope this helps.
I figured out a way to change my NAT type on my PC but it means I have to go into the router settings on my browser and go from there. However, I am currently at university which I presume is the reason I cannot get onto the router settings - because it's a shared router. Does anybody know how I can fix this?
If not, does anybody know how bad it is to play CoD on strict NAT type cus that's what I'm gonna be stuck with
