Access Server and DNS
DNS configuration options for Access Server include pushing specific DNS servers to clients and creating a split-DNS setup.
This page provides information about Domain Name System (DNS) and Access Server.
How DNS works
DNS is a protocol used on the internet to map computer names to Internet Protocol (IP) addresses using clients and servers. This is done through name resolution services. When you type in a domain name in your browser DNS translates it to an IP address so your browser can load the correct site. That's a basic overview.
DNS and Access Server
You can configure DNS for clients that connect to your Access Server. Access Server can have clients use the same DNS servers as the Access Server host, push specific DNS servers for clients, or not alter clients' DNS servers.
You can set these options in the Admin Web UI on the VPN Settings page.
You can also alter DNS resolution zones and default domain suffix settings on the VPN Settings page. DNS resolution zones allow you to configure a split-DNS setup, defining DNS zones to resolve by DNS servers pushed from Access Server.
An optional, Windows-OS-specific setting is the DNS domain suffix because Windows clients might only use the first domain provided in DNS resolution zones.
