[LUNI] Running 2 networks on same physical wire

[Jay Strauss]

Hi,

I need to have 2 computers sitting physically side to side to be on
different networks.  I only have a single RJ-45 outlet.  The whole
setup looks like:

            |-Router 1-                            |- Network 1
ISP--switch-|                --RJ45 outlet--switch-|
            |-Router 2-                            |- Network 2

The <blank> space between the routers and the RJ45 outlet is on
purpose, because I don't know what to put in there.

The RJ45 outlet is upstairs, and the routers are in my basement.  I
can NOT simply move the routers upstairs because there are numerous
computers hanging off of the routers in the basement.

I'm not sure if what I want to do is possible or what equipment I need
to get.  Any help/suggestions would be most appreciated.

Thanks
Jay
