I have configured a L2L tunnell between two ASA5505 running version 7.2(4) and I have this strange problem:
the tunnel is up and stable and I route 4 networks over the tunnel but every 2-3 days the tunnel stops forwarding traffic on one of the four networks (never the same network) and the only way to recover is to issue a:
clear ipsec sa on one of the two ASAs.
Looking at the ipsec counters when I have the problem I see that packets are sent but they are never received on the other end....
Does anybody have a clue on what is happening?
I have installed tens of ASAs and only these two are giving me this problem.
BTW both ASA use the same Internet provider...
thanks in advance and regards
