permit icmp echo-reply

access-list 100 permit icmp any host [external-ip-address] echo

access-group 100 in interface outside

Create an icmp conduit or access-list to permit the echo-reply.

Both the responses you got are incorrect. You will NOT be able to ping the outside interface address of the PIX from an inside host, nor can you ping the inside interface address from an outside host (even with a conduit).

It al has to do with the internal routing engine in the PIX, there is no way around it.
