Hey galdur, [img]graemlins/happywave.gif[/img] welcome to IW!
I may have bad news for you; I don't play multiplayer, but I seem to remember reading somewhere that HoW and ToLM have unresolved multiplayer issues (ie. lag) that the original did not have.
I'm not sure if there's a solution for you.
Edit: just ran a forum search, and
here is something that may give you some ideas on how to solve it. Also try
here, paying specific attention to Micah Foehammer's post. Apparently multiplayer is possible, it just requires some fiddling.
This also has some detailed info.
