For those curious before you try v0.99 BETA, here is the .git script file for WC3:

Code: Select all

Looks great, Ark. One question -

With the following configuration

LAN A (NAT/FW)
GIT only machine
game server machine (no GIT)

LAN B (NAT/FW)
gaming client (GIT)
gaming client (no GIT)

The GIT only machine would actually be configured with "The Server" option? (e.g., the game server can't support GIT)

Yeah well there are tons of odd configurations other then what the script allows for. Yes, you can pick "the server" for the GIT computer on the same LAN as the server. For WC3 there should be no issue since it does the tunneling of broadcast only and you need to open port 6112 via your NAT to the game server as well.
For other games where GIT is tunneling unicast traffic, if you separate the game server and GIT server, it may not work correctly if you use a switch instead of a hub, since GIT may not physically be able to see the same traffic the game server sees in that case.
