I am not familiar with the Cisco 2600. Let me try a couple of generic
router questions to try to elucidate the problem.
Presumably the router is your local DHCP server. In some way you can
control the range of IP addresses that it issues. When you set the
CentOS machine to use a static IP address, do you choose one that is
outside the DHCP range.
Also presumably the router forwards nameserver (DNS) requests to Cox.
When you say "haven't been able to connect" does that mean you do not
get the translation from hostnames to numeric IP addresses? Have you
looked at /etc/resolv.conf to see what the system is trying to use for
DNS?
Can you connect using a numeric IP address, thus bypassing the DNS translation?
I myself do not experience problems of this type using CentOS 5.2 with
a fixed IP address on my local network. I connect through a Netgear
router and a Motorola bridge/modem to Time-Warner RoadRunner.
