Well for one, you dont want to forward the GIT ports, or you create an infinite loop of forwarding a packet that is really a packet inside a packet being forwarded.
Yes, you will easily waste bandwidth, especially if you forward netbios ports such as 137-139 or 445 or other ports lots of traffic may appear on.
You don't want to forward traffic your ICQ or AIM is using, since that will just waste bandwidth, even if you are chatting on it sometimes.
Also, it may be a security risk to allow some ports to be forwarded, since anybody can inject packets into your local network, bypassing any external firewall or NAT, if they try hard enough. GIT will reject packets to any port you aren't forwarding, so if you set GIT up to only forward for a game, that game's ports is all that is exposed to the outside world if you are normally firewalled or behind NAT.
