I have successfully configured a tunnel between two pix 501e. THe problem is now, i cant ping the remote hosts, and they cant ping me. These are two brand new pixs so am i missing something?
Here is are some notables:
1. tunnel lights on on both PIX's
2. each host can ping their gateway
3. the two peers cannot ping each other (this is something i dont understand) ?
How can the tunnel be up, when the two peers cant ping each other?
Both configs are below... help!
Configs are attached!
here is my atlanta config...

config looks OK.
capture "show crypto ipsec sa" from both PIX.
then issuing a ping
capture "show crypto ipsec sa" again.
Comparing encryp/decryp count in two capture to see which one is NOT incrementing.
I am suspecting "routing" issue or your host has firewall which is blocking icmp.
