So - now that I've learnt how to play around with Hammer and can test my maps in TF2, this should be my last question for a bit...
I'm trying to host a game with my newly built map through the "Create Server" option in TF2, for me and some friends. I can set it up just fine, but everybody else can only see my LAN IP and not my external internet IP. So when they try to join, they get a "Server is not responding" error.
I'm certain this is because I am behind a router, and I have tried to find a guide or crucial tidbit of info to get around this, but no luck... :(
The ports Steam uses are all forwarded correctly on my router (incoming and outgoing).
So although this question has been asked lots for dedicated servers, is there any way I can simply use "Create Server" in TF2 and get it to use my external IP? Any advice greatly appreciated!
