I don't think that ip forwarding works with icmp, including pings. Can you
telnet accross the gateway?

Is it 2.1.x? If so you must switch on IP_FORWARDING at runtime too
(see release notes).

Quote:> The routers IP address is set as the gateway for the two networks.

What (in terms of raw hard facts) do you mean by this statement? The
most likely cause of the problem is that you have not completely and
correctly done this in both directions.

Probably - but since you don't say what you've actually done it's hard
to say what you've missed.
