Section 3 – Configuration DNS Setup To access the DNS Setup window, click the DNS Setup button in the Advanced directory. The Router can be configured to relay DNS settings from your ISP or another available service to workstations on your LAN. When using DNS relay, the Router will accept DNS requests from hosts on the LAN and forward them to the ISP’s, or alternative DNS servers. DNS relay can use auto discovery or the DNS IP address can be manually entered by the user.
Section 3 – Configuration 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.
Section 3 – Configuration VLAN To access the VLAN window, click the VLAN button in the Advanced directory. The Virtual LAN (VLAN) can group the devices even if they are not in the same LAN segment.
