Servers

Configuring servers means identifying DNS servers to the VPN 3002 so it can communicate with them correctly. DNS servers convert hostnames to IP addresses. The VPN 3002 functions as a client of these servers.

Configuration System Servers

This section of the Manager lets you configure the VPN 3002 to communicate with DNS servers.

This screen lets you configure the Domain Name System (DNS) servers for the VPN 3002. DNS servers convert domain names to IP addresses. Configuring DNS servers here lets you enter hostnames (for example, mail01) rather than IP addresses as you configure and manage the VPN 3002.

You can configure up to three DNS servers that the system queries in order.

Note DNS information that you add here is for the VPN 3002 only. PCs located behind the VPN 3002 on the private network get DNS information that is configured on the central-site VPN Concentrator in the Group settings for the VPN 3002.
