VPN gets disconnected randomly once in a while and i get the following error on the debug:

3|Jun 30 2009|11:46:27|713048|||Group = Grupo_VPNClient_Syges, IP =, Error processing payload: Payload ID: 14

3|Jun 30 2009|11:46:27|713902|||Group = Grupo_VPNClient_Syges, IP =, Removing peer from peer table failed, no match!

4|Jun 30 2009|11:46:27|713903|||Group = Grupo_VPNClient_Syges, IP =, Error: Unable to remove PeerTblEntry

4|Jun 30 2009|11:46:27|113019|||Group = , Username = , IP =, Session disconnected. Session Type: , Duration: 0h:00m:02s, Bytes xmt: 0, Bytes rcv: 0, Reason: Unknown

5|Jun 30 2009|11:46:27|713904|||IP =, Received encrypted packet with no matching SA, dropping

On the recommended actions says that it could be a misconfigured peer.

Could someone help me out to fix the problem?

I have this problem too.

The device we are using is an ASA 5505.

I have disabled “isakmp keepalive” in tunnel-group ipsec-attributes, using the command “isakmp keepalive disable”.

I have made the vpn-idle-timeout to none on the group-policy attributes.

DPD setting is set to maximum which is 480 seconds on the VPN Client.


- sysopt connection permit-vpn

- crypto isakmp nat-traversal

Have you got any more possible solutions?

Didnt you see this message ? Received encrypted packet with no matching SA, dropping . That is the problem.
