wine users - Mar 2009 - Joey the passion multiplayer

Hello,
So far i did
route -Fv -A inet add -host 255.255.255.255 eth0 as root but i can't get the
LAN option to work.
The other workstation can see me but can't connect to me if i host. If the
other pc host the game, i can't see it.
I have shorewall as firewall, which i guess is the thing blocking connection to
the linux workstation.So any clues to get around this?

Thanks in advance
