Netgear FVS318N User Manual

Click Apply to save your changes.

Click Test to evaluate your entries. The wireless VPN firewall attempts to make a connection 
according to the settings that you entered.

To verify the connection, click the Broadband Status option arrow in the upper right of the 

screen to display the Connection Status pop-up screen. (The following figure shows a 
PPPoE configuration; the IP addresses are not related to any other examples in this 
manual.) 

If your ISP requires MAC authentication and another MAC address 

has been previously registered with your ISP, then you need to enter 
that address on the Broadband Advanced Options screen for the 
WAN interface (see 

on page 50).

Configure Dynamic DNS 

Dynamic DNS (DDNS) is an Internet service that allows devices with varying public IPv4 
addresses to be located using Internet domain names. To use DDNS, you need to set up an 
account with a DDNS provider such as DynDNS.org, TZO.com, Oray.net, or 3322.org. (Links 
to DynDNS, TZO, Oray, and 3322 are provided for your convenience as option arrows on the 
DDNS configuration screens.) The wireless VPN firewall firmware includes software that 
notifies DDNS servers of changes in the WAN IP address so that the services running on this 
network can be accessed by others on the Internet.

If your network has a permanently assigned IP address, you can register a domain name and 
have that name linked with your IP address by public Domain Name Servers (DNS). 
However, if your Internet account uses a dynamically assigned IP address, you will not know 
in advance what your IP address will be, and the address can change frequently—hence, the 
need for a commercial DDNS service, which allows you to register an extension to its 
domain, and restores DNS requests for the resulting fully qualified domain name (FQDN) to 
your frequently changing IP address.
