Re: eCos Performance/ eth0,eth1 Routing problem (number of hops!)


I don't see any problem with the routing tables.  It's
curious (but not necessarily problematic) that your
ethx interfaces are also the default gateways.

I have a similar setup, except I have ppp instead of
eth1.  I am able to send a ping request to the PPP
interface, and have the ping response exit the
ethernet interface.  So, I'm reasonable confident that
your setup will work.  You can verify that by pinging
the eth1 interface through the eth0 interface.

Make sure that your ping source has a default gateway
of the eth0 and the ping destination has a default
gateway of eth1.  If that's correctly setup, then I
think you're just going to have to dig into the
source.
