[Apologies if you've already seen this message in other forums.]
Hi,
I have a very basic lab site to site vpn setup where I have a ASA 5505 running v7.2(4) on one side and a cisco 2811 on the other side.
What's my issue?
I can't seem to ping from cisco router to the 'inside' network of ASA (see config below) and can't seem to ping from ASA packets leaving the 'inside' interface to cisco router even w/ an ICMP ACL permit outside in. However I'm able to ping within ASA inside network & ping cisco 2811 side w/ packets leaving ASA 'outside' interface just fine.
example:
-------
ciscoasa# ping inside 10.20.20.1 (to cisco loopback1 from ASA inside)
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.20.20.1, timeout is 2 seconds:
?????
Success rate is 0 percent (0/5)
ciscoasa# ping outside 10.20.20.1 (to cisco loopback1 from ASA outside interface)
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.20.20.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms
ciscoasa# show run
