Ok I did this
Port Forwarding Borderlands on the Trendnet TEW-631BRP
But it didnt help, in my router menu i have em all enabled but borderlands still wont let anybody connect with me. And PFPortChecker also says they're closed. I also added all the ports to windows firewall exceptions.
I put my router's IP in the empty IP slot because it didnt accept anything else and blank also wasnt an option.
Whats the problem here folks?
EDIT: Could it have something to do with this?
This is not my picture.
My options are set like this:
UDP: 2nd option
TCP: 3rd option
