Hi Barry,
I use a somewhat similar setup here. Mine is probably a bit more
"schizophrenic" in that it has both RF and none RF addresses on the main
server, and several of the machines can boot up in different operating
systems, depending on what I am doing.

Anyway, I found it a lot easier as I had a "block" of eight IP addresses
allocated to me, aligned on an 8 bit boundary. The broadcast address is then
just the highest IP number, the network address is the lowest number, and
the netmask is just 29 bits.

I'd suggest that you get new IP numbers (contiguous) in the same way.

Hope this helps

Steve
