I have a cisco asa 5510 running 8.2 and a tunnel connected to what I believe is a Fortinet device.
The errors in my ASDM 6.2 real time log state:
3 Nov 04 2011 12:01:09 713902 IP = 142.46.x.201, Invalid packet detected!
4 Nov 04 2011 12:01:08 713903 Group = 142.46.x.201, IP = 142.46.x.201, Error: Unable to remove PeerTblEntry
3 Nov 04 2011 12:01:08 713902 Group = 142.46.x.201, IP = 142.46.x.201, Removing peer from peer table failed, no match!
6 Nov 04 2011 12:01:08 713905 Group = 142.46.x.201, IP = 142.46.x.201, Rxed Hash is incorrect: Pre-shared key or Digital Signature mismatch
5 Nov 04 2011 12:01:08 713041 IP = 142.46.x.201, IKE Initiator: New Phase 1, Intf NYGHINT, IKE Peer 142.46.x.201 local Proxy Address 192.168.x.0, remote Proxy Address 10.21.x.0, Crypto map (SSHAEXTERNAL_map3)
These errors just keep repeating but occasionally the tunnel will come up for an unknown reason. I know that the preshared keys match and that all the crypto maps etc are correct. This is the first tunnel on a new ASA and that may be a factor but I am not sure.
Why does the box tell me I have a pre-shared key mismatch when I know I don't? I am not using certificates either, so the Digital Signature piece is not the issue.
Any help would be appreciated, I can post the config if that would help.
