You can't find it in D.O.G.? Or in my guide? Make sure you have the IPX protocol installed on your machine
Now go to the “Data Communications” category. Select “Enable IPX” and determine which one of your buddies is going to be the host. Whomever is hosting should pick “Server” and enter their IP address. For everyone else at the party, select “Client” and enter the host’s IP into the given field.
