Let's see, hopefully this helps

        GEP  = 65.88.136.33     (external Gateway,eth0, Cisco Router)
        GIP  = 192.168.101.20   (internal Gateway,eth1)
        DIP  = 65.88.136.62     (eth0)
        VIP1 = 65.88.136.61     (eth0:0 on director, loopback on realserver)
        RIP1 = 192.168.101.2    (belonging to VIP1)

I'll try and explain the best I can. I'm not 100% on the terminology but
here goes.

65.88.136.61 is the Address that I want the Internet to see (DIP?) and is
also the VIP for redirection to the RealServers. The RealServers have a
default Gateway of 192.168.101.20 (My internal Network).

>what is a domain controller is regular-speak? a switch/router...?

My Domain Controller is also my Network Internet Router, Windows 2000 Server
with Routing and Remote Access

Yes

I can connect to the VIP on the director from the same network as the RIP,
but cannot connect to the network from the other side of the Router which
connects to the director.

I know its almost identical to what you put, but it was almost exactly what
was going on.

Let me know if this helps.

Thanks,

Bill
