Could you list a few things like hardware, distribution, kernel
version, etc?
Also.. if this happens often, jump on the Linux box and do the
follow for good diagnotics:
arp -a
cat /proc/net/dev
cat /proc/sys/net/ipv4/ip_forward
for 2.0.x kernels: ipfwadm -M -l
for 2.2.x kernels: ipchains -M -L
Then run
"tcpdump -i eth0 > /tmp/eth0& tcpdump -i eth1 > /tmp/eth1; killall tcpdump"
Now, try to access the Internet and send us the logs.
