I have an ASA5510 ver8.0(3), its running EIGRP. From the ASA all EIGRP routes/subnets are learned and are pingable. My issue is when I set my PC's default gateway to the ASA inside interface, I'm unable to reach any other subnets or eigrp routes that my ASA could reach.
Are the other subnets reachable via the inside interface ? If so the ASA would need to send the traffic from your PC back out the inside interface and you need to set this up -
Other than that have you
1) checked that what you are trying to ping has routes back to your PC subnet
2) that you are allowing ICMP with access-lists on the relevant interfaces
