From WoWWiki
Allo, I'm Gandork. I play primarily as a Gnome on Mal'Ganis. I'm interested in writing mods for WoW, but can't seem to find any good documentation.
I'm also seeking a way to force all data on the outgoing TCP port 3724 (yes, that's the WoW port) to be redirected to another host:port, for the main goal of Proxying WoW. If anyone knows how to do this, PLEASE leave a message on my talk page. Thanks.
