Dear Friends,

Getting errors when connecting to a newly configured VPN Gateway.

Scenario: ADSL router forwards 500 & 4500 packets to VPN Gateway.

Please see the attached configuration txt for the IOS being used, and have also attached the debugging error.

VPN Client Used: Cisco Systems VPN Client Version

Would really appreciate someones help in solving this issue.


I have this problem too.

It seems that the negotiation was failed in phase 1 so IKE SA was not created.

I think the following: *Aug 28 05:23:35.619: ISAKMP:(0:0:N/A:0): vendor ID is XAUTH implies that the client wants extended authentication, but it is not configured on the gateway.

Let's try to add the followings:

username dummy password whatever


aaa authentication login userauthen local

aaa authorization network groupauthor local


crypto map clientmap client authentication list userauthen

crypto map clientmap isakmp authorization list groupauthor

In this case the router will do an xauth using local database so when the client prompts for username password use the dummy/whatever username password.

Anyway I don't know whether the xauth can be turned off in the client, but I know I have a very similar setup which works with 4.8.02 client.

Hope it helps,
