We have a Cisco ASA 5510 that had a VPN tunnel established with the previous network administrator's home connection. When he resigned, we deleted the tunnel-group. I've noticed, however, in the logs we still see:
|4||Dec 28 2014||07:51:26||Group = DefaultL2LGroup, IP = x.x.x.x, ERROR, had problems decrypting packet, probably due to mismatched pre-shared key. Aborting|
Where the x.x.x.x is the guy's home IP address. I tried grepping his IP in show run and all I found were an acl entry. Is there any way to get DefaultL2LGroup to stop trying to reestablish this tunnel?
