I created VPN L2L between ASA 5520 and ASA5510 since 4 mothes , it worked fine
but since yesterday , the ping is fail although the tunnel is UP
I checked the ACL ,and the routing but still the same problem
so what do you think?
I would recommend to you checking the following:
1- show crypto ikev1 sa
2- show crypto ipsec sa peer remote_peer_public_ip
1- Is the tunnel up?
2- Is the ASA encrypting your ICMP packets?
Please make sure to at least verify the basic stuff, like the state of the VPN tunnel, for instance.
1.show crypto isa sa
2.show crypto ipsec sa
Can you provide the outputs.
