I would check your translation rules in the firewall. I think most
firewall's require some sort of translation, whether it be NAT/PAT or static
or keep original address. Also, is the subnet between router A and B
routeable? Is it NAT'd? Does the firewall have a route for that subnet?
Can the firewall reach that subnet? Do a debug ip icmp on RouterB and do an
extended ping using S0 as the source from router B and send it to the
list....Also extended trace as well. I bet the firewall either doesn't have
a route or there's no translation for the subnet..
Just a couple quick questions..
