Which ports does WOW use? Port forwarding sounds like what you need to do. We would need details of your router brand & model name & numbers. Plus the ports needed, though we might be able to research that. (Oh, and also which operating system you are using.)

What is CSS? Likewise, we'd need to know the ports required. Some of those games may need more than one port, particularly if they use voice for example.

i know this is a fairly old topic but im in need of the same help , im currently at uni and cannot get on wow, im quite computer literate and know my way around a computer im just not too big on networking , ive read about port forwarding may work for it but i have no clue at all, any help would be nice, but the port that you need for world of warcraft is 3724 TCP, once again any help would be great cheers
