Hi,
I thought the below is to permit traffic between same interface but in
my case its different interfaces (outside / inside) between different
security level (0 / 100).
Used the below w/ no avail.
ciscoasa#same-security-traffic permit intra-interface
I even tried,
ciscoasa#same-security-traffic permit inter-interface
Still no luck.
regards,
sky

Hello,
IIRC hairpinning is disabled by default on ASA. You have to enable via:
"same-security traffic permit intra-interface"

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 my issue?
I can't seem to ping from cisco 2811 to the 'inside' network
of ASA (see
config below) and can't seem to ping from ASA 'inside'
network to the
'outside' network towards cisco 2811 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
