I'm trying to get a user in another city to connect to one of our 3005 concentrators using IPSec/TCP (we've also tried IPSec/UDP) and the Cisco VPN client 4.0.1. So far, we can't seem to get past a certain point. Where I think it's trying to ask for a username and password (after checking the certificate), I get this in the logs:
Xauth required but selected Proposal does not support xauth, Check priorities of ike xauth proposals in ike proposal list
and the client eventually gives up.
If, as an experiment, I get him to try connecting to our other 3005, which should be very similar in configuration, he connects fine.
I've compared the two configs and I don't see any differences in the IPSec stuff. What should I do to get this problem fixed?
Thanks!
