Hi Bruce,
> You don't say what version of the kernel you are using or what network
driver. Until you get things set, I'd use a static IP just to eliminate
one variable.
The base LFS is 6.5 with kernel 2.6.30.2.

the same problem? You'd have to use dchp there though.
This is how I had it set up before I got the router. To double check
everything still works, I put it back how it was, and yep no problems.
> Are you using iptables at all?
I ran `iptables -S' and obtained:
-P INPUT DROP
-P FORWARD DROP
-P OUTPUT DROP
-A INPUT -i lo -j ACCEPT
-A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT
-A OUTPUT -j ACCEPT
I can't remember whether these are default settings or whether I put these
in myself...
> Is there any possibility that there is more than one system using the
same IP address?
This occurred to me. I previously assigned 192.168.1.1 to eth1. When I
first tried setting up the router from Ubuntu, I encountered problems due
to this address conflict. However, I have done my best to ensure that
these conflicts have been removed. Running `grep --recursive 192.168.1.1
/etc' gives only one result,
/etc/sysconfig/network-devices/ifconfig.eth0/ipv4:GATEWAY=192.168.1.1
I believe this is correct for accessing the net through the router. If
there was a settings conflict somewhere, I would expect the grep command
to return more results than this.

I ran these commands from within a chroot environment within Ubuntu.
Ubuntu has (annoyingly) swapped eth0 and eth1, so keep that in mind when
reviewing the following results:
ifconfig -a

route -n

0.0.0.0 192.168.1.1 0.0.0.0 UG 0 0 0 eth1
In addition to your suggested commands, I also ran `ip route show all' and
obtained,
192.168.1.0/24 dev eth1 proto kernel scope link src 192.168.1.2 metric 1
169.254.0.0/16 dev eth1 scope link metric 1000
default via 192.168.1.1 dev eth1 proto static
Running the same command in Ubuntu gives the same result.
