Domain
Enter the name of the registered domain in which the VPN Concentrator is located; e.g., altiga.com.
Maximum 48 characters. This entry is sometimes called the domain name suffix or sub-domain. The
DNS system within the VPN Concentrator automatically appends this domain name to hostnames before
sending them to a DNS server for resolution.
Primary DNS Server
Enter the IP address of the primary DNS server, using dotted decimal notation; e.g., 192.168.12.34.
Be sure this entry is correct to avoid DNS resolution delays.
Secondary DNS Server
Enter the IP address of the secondary (first backup) DNS server, using dotted decimal notation. If the
primary DNS server doesn’t respond to a query within the
Timeout Period specified below, the system
queries this server.
Tertiary DNS Server
Enter the IP address of the tertiary (second backup) DNS server, using dotted decimal notation. If the
secondary DNS server doesn’t respond to a query within the
Timeout Period specified below, the system
queries this server.
