As root, look at the output of "route" to make sure that you are routing
packets correctly (that is, through eth2).  Also, check that your firewall
permits the packets (it might pass dhcp packets but not ping).  You may
have to turn off eth1 or eth0 (whatever the normal ethernet connection is).  

Also, try pinging the laptop from the gateway, with tcpdump running on
both ends.

Hope that helps;
