for one eth1 should have no gateway. i don't know if this would cause the
problem your having but it might. just keep the gateway on eth0 if traffic
is going out there. also be sure ip forwarding is turned on.
if your using kernel 2.2:
echo 1 >/proc/sys/net/ipv4/ip_forward
also if your doing IP MASQ be sure the rules are enabled/configured right.
and be sure that all other machines are using 192.168.1.1 as their gateway
if this machine is the only router/gateway.
