I am working right now with a single router. Ethernet connection is pointing towards my firewall and my serial connection my internal network. I can ping my firewall from my router but if I do a extended ping I cannot reach my firewall from my internal network.
2500B#ping 192.168.20.98
Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 192.168.20.98, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 1/12/48 ms

Gateway of last resort is 192.168.20.98 to network 0.0.0.0
192.168.40.0/30 is subnetted, 1 subnets C 192.168.40.0 is directly connected, Serial0 192.168.20.0/28 is subnetted, 1 subnets C 192.168.20.96 is directly connected, Ethernet0 S* 0.0.0.0/0 [1/0] via 192.168.20.98
I am unable to reach my firewall at 192.168.20.98 from 192.168.40.2 s0.
I have been working on this a few days and cannot figure it out.
