reposting some general info that someone sent through the website for anyone who's interested:
I would like to let the team at en.war2.ru know that to play local TCP/IP games over LAN ipxwrapper "http://www.solemnwarning.net/ipxwrapper/" will work well. Played with 4 plays on a local LAN with no issue.
Main for a great LAN party!
