when i use VPN Client to connect to my VPN network using real IP ,this message appears as in attached picture ,

please if anyone can see the problem and tell me how to solve it by ASDM GUI or CLI , but i preferred ASDM..

Note : VPN tunnel should connect to Internal Network IP Range 192.168.3.X
which is accessible by ASA as you see from redirection to 192.168.3.229

thanks everyone

unclerico · May 14, 2010

here's one thing:

Code:

no sysopt connection permit-vpn

i don't know ASDM so I can't tell you where to enable this feature in the GUI, sorry. if you want to get into the CLI you will just issue sysopt connection permit-vpn.

you will also need to add this line to enable communication from your 3 network out to your vpn clients:

Code:

access-list inside_nat0_outbound extended permit ip 192.168.3.0 255.255.255.0 192.168.14.0 255.255.255.192

i would do two things:
1) make sure that the pre-shared key for the tunnel-group is correct
2) add in another isakmp policy:

Code:

crypto isakmp policy 20
 authentication pre-share
 encryption 3des
 hash sha
 group 2

post back the debugs when you try to connect again.
