L13 can handle more than one DDNS hostname. You can define more than one hostname for a single WAN connection
by simply repeating the procedure above for the same connection.
When you have finished activating the DDNS service, you can verify that it was activated correctly.
 To verify that DDNS is activated for a hostname:
Browse to the hostname (e.g., http://itsp.dyndns.org). If the hostname is resolved correctly, the L13 WBM
login page opens.
3.7.5 DNS Server
Domain Name System (DNS) provides a service that translates domain names into IP addresses and vice versa. The
gateway's DNS server is an auto-learning DNS, which means that when a new computer is connected to the network
the DNS server learns its name and automatically adds it to the DNS table. Other network users may immediately
communicate with this computer using either its name or its IP address. In addition your gateway's DNS:
 Shares a common database of domain names and IP addresses with the DHCP server.
 Supports multiple subnets within the LAN simultaneously.
 Automatically appends a domain name to unqualified names.
 Allows new domain names to be added to the database using L13 WBM.
 Permits a computer to have multiple host names.
 Permits a host name to have multiple IPs (which is needed when a host has multiple network cards).
The DNS server does not require configuration. However, you may wish to view the list of computers known by the
DNS, edit the host name or IP address of a computer on the list, or manually add a new computer to the list.
