ASA Vpn and DNS

Hi,

I have a question.

We have some VPN with Cisco ASA 5520.

The laptops are part of the corporate domain (Microsoft Active Directory) and are associated with the internal DNS. When you connect to VPN, the internal DNS is not updated with the IP address of the VPN. If I check the laptop name connected in VPN with nslookup I get the address of the internal LAN (where the laptop is registered before) and not the VPN address. Is there a way to update the dns entry when the client establish the VPN? Does the ASA or the AnyConnect client can do that?

If the configuration of DHCP server is on the ASA you try to execute this command :

dhcp-client update dns

Check the group-policy configuration on the ASA to see if you are pushing any DNS server IP. If it is configured then the Client PC's VPN adapter, once connected to the VPN, should get this IP address. This applies to both Anyconnect and Remote access vpn clients.
