Hello. I've got a site to site tunnel configured in an ASA-5540 (8.3) and at first working fine. After several hours, the tunnel is disconnected and I this log appear without stopping:
%ASA-7-710006: ESP request discarded from "tunnel IP peer" to outside_int:"my tunnel IP"
I can't figure out why the tunnel stop working and the meaning of this message. The explanation in Cisco documents does't fix to me.
Thanks.
