Very Computer

1. Can't reach the outside world

Until now we have been using OS/2 Warp 4 almost exclusively and have
been able to surf the net from any of our three computers. We use a
router/firewall consisting of a fourth dedicated computer, also running
Warp 4, connected between the cable modem and the LAN.

We have just installed RedHat Linux 6.1 on one of the machines, and
although all the machines can still ping each other, the Linux box
cannot make contact with "the outside world" -- not even the "public"
side of the router, i.e., the dynamic IP address assigned by our ISP.

Linux ia all prestty new to me. Where do I start looking for the
problem?
