I have opened the required ports on 27015, 27016 and 8766 as per instructions i have found on this site and others yet still get the same issue and my PC cannot be seen via those ports when i test them with a port checker.
I am using a BT HomeHub2 and i am not sure if if might be damaged, although i doubt this as i can run every other game i have with no issues online.
I am running Windows 7 Ultimate.
I have made sure the hubs firmware is up to date and even done a reset of the hub but still no luck.
Any help appreciated.
