I can't seem to host in wwp. I did all the things in the faqs (opened ports and changed regedit) but when people try and join they still see my ip as my local network ip. Any ideas?

well,i'm having the same problem
i'm out of ideas :|

hmmm...regedit and go to HCU\software\team17...\Worms...\NetSettings
There are 2 important keys:
LocalAddress - your external IP (whatismyip.com)
Address override - must be 1

Check if your port is opened on http://www.t1shopper.com/tools/port-scan/
Ask a friend to check on site your IP and port 17011 WHILE you are hosting a game.
