VPN 3000 Client Auth not working

Getting the following error when trying to authenticate to VPN 3020: Xauth required but selected Proposal does not support xauth, Check priorities of ike xauth proposals in ike proposal list

Not really sure what this means.

Re: VPN 3000 Client Auth not working

Find the IKE proposals on the VPN3020 (location varies with version so I can't tell you where). You will find some are active, others not. Ensure that one is active where the authentication method is "pre-shared keys (xuauth)" with something like MD5, 3DES, DH group2.

If you see a proposal named "CiscoVPNClient-3DES-MD5" then that will do the trick.
