Step by step guide for a home network

[Starhunter]

Hi,
can anyone give me a step by step giude to set up KRP on a home network with three users.
I cannot see the other gamers when I try to work out how to connect them.

I can see them on the network and we all share the internet and play other games across the network OK but I cannot get KRP to see the other players.

Thank you
