Cisco ASA Remote-Access VPN - PeerTable Entry errors - preventing login

Last Modified: 2012-05-11
Hi Team

I've got a coworker who uses vpnc (on ubuntu) to access our production and dev networks over a VPN connection to a Cisco ASA 5520.

Just recently his login started failing, and the errors that I am able to catch in the logging are this:

Error: unable to remove PeerTblEntry
Removing peer from peer table failed, no match!

I actually use a VPN/Ipsec entry on Mac OS X 10.6, and I can access the VPN fine. As soon as I change the connection settings to his account, I get the above error messages in the logging console.

I've tried removing and recreating his account, with different usernames, a few times now, and it consistently fails.

I'm not an expert on this, but seems that some type of IPSec negotiation is not occurring correctly, but this is conjecture.

we're not using TACACS+, just local database of usernames and passwords. Again, this isnt a Site-to-Site, just standard Remote-Access VPN.

Any ideas?
