Problem - Debian 2.1 with linux-2.2.13 won't connect to @home network



I've been working at this for a little while now and here's what I've
found out.

I installed debian 2.1r4 over my redhat 5.2 firewall.  The installation
worked well, and I was able to install packages via apt, upgrading to
potato, from http://http.us.debian.org and other sources without
difficulty.  When I rebooted my machine after the upgrade to potato, the
networking ceased to function.  

I then tested on a dual boot redhat and corel linux machine, and found
that I can ping my gateway from RedHat, but not debian.  (The corel linux
box is essentialy slink with a 2.2 kernel.)  Therefore the issue is not
hardware specific, nor specific to potato.  

I searched the lists and found a post by David Wright which suggested that
there was a problem with the 2.2.x kernels and the arp cache under slink.
Basicaly, when the arp entry was published it killed the hardware address 
on his machine.  I'm not certain that this is what's happening with my
machine, but the my symptoms are similar.

I've checked to see that the firewalling rules were ok.  ipchains -L shows
policy accept for all chains.  Therefore this isn't the case.  Iplogger
shows the following lines in it's log file for all the ping's I attempt to
send to my gateway.

destination unreachable from my_ip_addr

I've commented out the ALL: line from /etc/hosts.deny

The routing table and interfaces are configured properly

          TX packets:228 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0

The next step I can see is to take the route and ifconfig binaries from my
redhat machine and use them under the deb machine to see if the problem
lies in the binaries I am using.  

Does anyone have any ideas as to what I've missed/done wrong?
