Q: Built-in IPsec VPN randomly drops to Cisco VPN server

I'm using the built-in IPsec VPN client on Lion and the VPN connection randomly drops.  I've found this in the system.log file corresponding to the time when the connection drops:

 

Aug 20 10:00:34 MBP racoon[38259]: IPSec Phase1 started (Initiated by me).

Aug 20 10:00:34 MBP racoon[38259]: IKE Packet: transmit success. (Initiator, Aggressive-Mode message 1).

Aug 20 10:00:34 MBP racoon[38259]: IKEv1 Phase1 AUTH: success. (Initiator, Aggressive-Mode Message 2).

Aug 20 10:00:34 MBP racoon[38259]: IKE Packet: receive success. (Initiator, Aggressive-Mode message 2).

Aug 20 10:00:34 MBP racoon[38259]: IKEv1 Phase1 Initiator: success. (Initiator, Aggressive-Mode).

Aug 20 10:00:34 MBP racoon[38259]: IKE Packet: transmit success. (Initiator, Aggressive-Mode message 3).

Aug 20 10:00:34 MBP racoon[38259]: IPSec Phase1 established (Initiated by me).

Aug 20 10:00:34 MBP racoon[38259]: IKE Packet: receive success. (Information message).

Aug 20 10:00:34 MBP racoon[38259]: IPSec Extended Authentication requested.

Aug 20 10:00:34 MBP configd[16]: IPSec requesting Extended Authentication.

Aug 20 10:00:34 MBP configd[16]: IPSec Controller: XAuth reauthentication dialog required, so connection aborted

Aug 20 10:00:34 MBP configd[16]: IPSec disconnecting from server xx.xx.xx.xx

Aug 20 10:00:34 MBP racoon[38259]: IPSec disconnecting from server xx.xx.xx.xx

Aug 20 10:00:34 MBP racoon[38259]: IKE Packet: transmit success. (Information message).

Aug 20 10:00:34 MBP racoon[38259]: IKEv1 Information-Notice: transmit success. (Delete IPSEC-SA).

Aug 20 10:00:34 MBP racoon[38259]: IKE Packet: transmit success. (Information message).

Aug 20 10:00:34 MBP racoon[38259]: IKEv1 Information-Notice: transmit success. (Delete ISAKMP-SA).

 

Is there a hint here as to any configuration I can change on the MBP, or anything I can ask the network admin to change on the Cisco device to resolve this?

 

Thanks,

Guy

    I have read this article with interest as I'm in the same position as most here, in that I need to use VPN for more than one hour at a time.

    I must say that I'm absolutely put off and disgusted by the way this is being handled by the firm responsible.

    Having said that, does anyone know why this seems to malfunction mostly when using Cisco routers but seems to be working properly with many other router types?

     

    Kind regards

    Hans
