Yes, I know I could do that. It's OK when there are only 2 boxes but what if I had a small office setup with, say, 100 PCs. It's not so practical then. I'm interested in finding out if there is another way to make this work.
Rather than having the WRTG run the DHCP, let your FC machine do
that. Configure DHCP on FC to hand out the same IP for the WRTG, and
set the rest of the pool as dynamic - this way the router will always
have the same IP, which you can then use as the gateway for your
network. The other machines can have their IPs change if they so
desire. Then, on the same FC box, you also set up a local DNS server
and let DHCP dynamically update it. Set all the machines to use the FC
as their DNS server and voila. It no longer matters if the IPs change
on the machines since the FC box will always have an updated list to
hand out.
As a practical example, I have this setup at the company where I
work. Our gateway also runs our DHCP server, and that same machine also
runs a DNS server for the local network. When DHCP hands out an IP for
a machine on the local network, it also notifies the DNS server which in
turn creates an ARPA entry in the 192.168.x.x range as well as insert an
entry in the main domain name we use internally. Now, any machine can
simply type in the name of another machine to get to it (as opposed to
having to figure out what their IP is each time.)
In a way this would be overkill for simply two machines, which is
what your initial request was for. But if you plan on expanding, then
it would make more sense to do DHCP with a dynamic DNS.
