If you choose to Disable DNS Relay , it will be necessary to configure DNS settings for hosts on the LAN since they will
not be depending on the Router to forward the DNS requests.
When you have configured the DNS settings as desired, click the Apply button.
Note
To use DNS Relay for computers on your local network, DNS Service Filtering must be
disabled. See the Firewall section in the next chapter.
Dynamic DNS
The Router supports DDNS (Dynamic Domain Name Service). The Dynamic DNS service allows a dynamic public IP
address to be associated with a static host name in any of the many domains, allowing access to a specified host from
various locations on the Internet. This is enabled to allow remote access to a host by clicking a hyperlinked URL in the
form
hostname.dyndns.org , Many ISPs assign public IP addresses using DHCP, this can make it difficult to locate a
specific host on the LAN using standard DNS. If for example you are running a public web server or VPN server on
your LAN, this ensures that the host can be located from the Internet if the public IP address changes. DDNS requires
that an account be setup with one of the supported DDNS providers.
