Configure WINS and DNS Servers

Mobile VPN clients use shared Windows Internet Name Server (WINS) and Domain Name System (DNS) server addresses. DNS translates host names into IP addresses, while WINS resolves NetBIOS names to IP addresses. These servers must be accessible from the Firebox or Firebox trusted interface. Make sure you use only an internal DNS server.

For more information about how DNS is used for lookups over a mobile VPN connection, see DNS and Mobile VPNs.

In the network configuration, you can specify WINS and DNS servers to use. DNS forwarding is not supported for mobile VPN clients.

Although you can add up to three DNS servers, the mobile VPN clients use only the first two in the list.

For PPTP and L2TP Mobile VPN clients, the Domain Name specified in the network DNS settings on the Firebox is not used as a domain name suffix. You can manually assign the DNS servers your PC uses for an L2TP or PPTP VPN client connection, and specify the DNS suffix the client computer uses to resolve host names when it is connected to the VPN. For more information, see the Knowledge Base article, Configure DNS settings for L2TP and PPTP VPN clients.
