[WaW] How to host a zombies server?
I really want to play zombies with some friends, but can't for the life of me figure out why it won't work. I believe I've taken all the necessary steps but still can't get it to work. Players are able to join my lobby just fine, but when I start the game it either hangs at the loading screen forever or my friends get a connection error. However, when I host a regular multiplayer game such as FFA, everything works fine and people are able to connect no problem so long as I host it as a dedicated server (hosting as a listen server won't work, which seems like that might be connected to why zombies won't work).
Here is everything I've done so far:
Opened up all ports listed here
Set a bypass rule in my firewall
Ran the .exe as administrator
Replaced my .exe with the LAN fix (those connecting also tried it)
Set the max ping to 999
Uninstalled and reinstalled
Windows 10 Pro 64-bit
Intel i7 5820K
GTX 1080 4GB
Any help would be much appreciated.
