Your first machine's (gateway) routing table does not show your LAN side
(192.168.3.(65??) (possibly on eth1 as UH)) as being recognised and up.
Do run an ifconfig and check if the LAN side interface on your gateway
machine is up and working. Check using ping from gateway to second LAN
machine and the reverse too.
