However, from the cisco router, I cannot ping past eth1 on the linux box. The reverse is also true; I cannot ping past eth0 from a host on LAN. proxy-arp is enabled on the linux box and the route to a.b.c.0/24 is added to the cisco router. I haven't a clue why either way, I can only get to the far side of the linux box but no further. On second thought, maybe this is not an application for proxy-arp. Your thoughts are appreciated.
