Subject: [LARTC] proxy arp and routing
Date: Fri, 01 Feb 2002 22:41:49 +0000 [thread overview]
Message-ID: <marc-lartc-101260332616001@msgid-missing> (raw)
Hello,
Given the network map below, I am able to ping any ip on all networks from the
linux box. 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.
