Cisco VPN client issue

Hi All,

    Ex :   abcdcorp.com -->10.1.1.100-->211.1.100

     10.1.1.100  --> Intranet server IP address
     211.1.1.100  --> Natted IP address of Intranet server.

If we access from Corporate network it resolve as 10.1.1.100 and over the internet it would be as 211.1.1.10.

 Issue is when we connect through VPN it must resolve as 10.1.1.100 but it resolved in the public IP 211.1.1.100, even though it was allowed to access over VPN.

 Real issue comes here if this particular IP access over the internet it will not allowed to access other links as per our Corporate policy.

In Vista alone we have this porblem, we able to connect the Cisco VPN client without any issues. After connecting into the VPN we are not able to resolve intranet sites, even though IPs are allowed to access over the VPN.

Note : By adding host entry it works without any issues. Its possible to make host entry for more than 120+ servers.

Details : Cisco ASA 5510 , 7.2 IOS version, VPN client 5.0x

Kindly share your experience to resolve this issue.

Regards
Nazir

Hi,

Here with attached the config file

@greekstones

If it is DNS issue on your VPN policy map, how it works flawlessly for years on 2000 and XP machines , only Vista we face these problem.

@ikalmar

VPN clients receiving IP and DNS address through DHCP server . Are you meant to say this ??

This is a known issue with 7.0.x versions of ASA code.  Upgrade to 8.2 and it'll fix the problem.  --TX
