I have an ASA5520 and about 10 5505's. All running Site to Sites. The tunnels are up and everything has been running fine. Although on the Local side i can't ping the remote ASA, but i can ping all the devices behind it. On the remote side i can ping the 5520 and everything else on my network i am allowing. When i watch the log in the ASDM on the 5520 nothing shows up related to the ping to the 5505. On the 5505 i don't see where it is blocking ICMP. It just says
"6 Aug 14 2008 05:40:49 302020 10.0.3.69 192.168.1.101 Built outbound ICMP connection for faddr 10.0.3.69/512 gaddr 192.168.1.101/0 laddr 192.168.1.101/0"
"6 Aug 14 2008 05:40:49 302021 10.0.3.69 192.168.1.101 Teardown ICMP connection for faddr 10.0.3.69/512 gaddr 192.168.1.101/0 laddr 192.168.1.101/0"
This is normal traffic for a S2S i assume. While i'm trying to get this working i have this configured,
icmp permit any inside
icmp permit any outside"
