Yes, I believe you're right.

I don't know; I don't know anything about how networking works. I think they
are assigned specific addresses from within the reserved range of 192.x. (see

Both the Linksys and the IPCop are in the 192.168.x range. I did set the IPCop
to a fixed address within the range that the Linksys supports, different from
the router address itself.

I "think" we have a static IP address from Cox. Looking at the printout of our
specs from Cox it looks that way, and my boss says we do, too, -he says we're
not using DHCP. Neither of us know much about networking. I'll try to post
some additional information tomorrow from work, if I can.
Thanks for your help.
