Reference Manual for the Model FVM318 Cable/DSL ProSafe Wireless VPN Security Firewall

Configuring Dynamic DNS

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. In this case, you can use a commercial
dynamic DNS service, who will allow you to register your domain to their IP address, and will
forward traffic directed at your domain to your frequently-changing IP address.
The firewall contains a client that can connect to a dynamic DNS service provider. To use this
feature, you must select a service provider and obtain an account with them. After you have
configured your account information in the firewall, whenever your ISP-assigned IP address
changes, your firewall will automatically contact your dynamic DNS service provider, log in to
your account, and register your new IP address.
