Tweaker, we are using SP2 but behind a router: windows firewall is off, there are no software firewalls.
I have gone into the network connection on the main PC and added the services for LFS there as well - have tried using its own IP address, as well as that of the router.
We've followed the instructions to set new services in router, and router firewall knows to forward those services to the ipaddress of the "host" PC.
That seems to work OK, and we can connect to that host using a second pc behind the firewall - but only by entering the specific IP address of the host PC. We can't make it "go out to the Internet - then come back again".
It did work once today, in that when I was setting up my PC a couple of drivers managed to jump in ! BUt I can't do it myself, so to speak.
What I mean is: Main PC "hosting" multiplayer game. Laptop looking to join that specific game either by choosing from lfsworld or by typing name in "join specific game". In either case, I get the clientconnect error mentioned above. (Perhaps its normal not to be able to connect in this way?)
Host PC is S2 licensed, hosting a demo game. Laptop is demo.
Any clues welcomed, as we seem to have exhausted the help / links from this forum !
Thanks...
