I built my own CS:S GCF standalone for my friends so we can do LAN party. Myself I'm using legit Steam client. On my first attempt my friend can find my LAN server in LAN browser, but he can't join. There's an error "LAN server are restricted to local clients (Class C)." So he hosted the LAN, but I can't find his server on LAN Browser. I still can play by using connect command to his network address though. There's two questions there. How can RevEmu join with my LAN server with legit client? And vice versa?
