The cilents are using the TS_group. Could you tell me how to debug the vpn client seesions? It appears debug crypto isakmp and debug crypto crypto ipsec both not working for this.

PS: I understand that group-policy can be inherited. Normally, only the value from cisco default policy would be inherited to customized policies?

Thanks,

Victor

Victor,

Yes, by default group-policy inherits on default policy and RA tunnel-groups inherit from default RA tunnels group.

If there are not debugs on ASA it's very strange, but maybe check if you're not running "debug crypto cond ..." from some other time? (You can do "debug crypto cond reset")

Re client debugs:

In client GUI -> Log -> Logging setting -> set everythign to "3". -> "OK" it.

Restart the client.

Logging should be enable on client side.

Marcin

Marcin,

So there seems no wrong on the confuguration? I just got another report that one user was kick out when he was using the tunnel. But haven't got chance to do debug yet.

Thanks,

Victor

Victor,

There's nothing wrong with the config that I see.

There may be some interactions with radius for example (max users setting or similar) :-)

Debug on ASA and logs from client are minimum to move forward. I will be out of office for two weeks so I might not be able to provide much input ;[

Marcin,

I got some debug infor on ASA, but the user forgot to enable logging on the client....

The whole seesion established for about 18 minutes and the idle time is less than 5 min, then it's disconnect.

Regards,

Victor

Victor,

OK, so we know that disconnect comes from client "Reason: Peer Terminate". (The root cause might not be on client)

Looks to me like something in the way DPDs operate.

Will a user get disconnected if you run continous ping via tunnel?

Marcin

Yes, even with continus ping, it disconnected. But I only allow RDP and DNS traffic for the tunnel, should this affect?

rgs,

Victor
