Configuring Dynamic DNS (Optional)

Dynamic DNS (DDNS) is an Internet service that allows routers with varying public IP addresses
to be located using Internet domain names. To use DDNS, you must setup 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 on the Dynamic DNS Configuration screen.)
The VPN firewall firmware includes software that notifies dynamic DNS 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 FQDN to your frequently-changing IP address.
After you have configured your account information in the VPN firewall, whenever your
ISP-assigned IP address changes, your VPN firewall will automatically contact your DDNS
service provider, log in to your account, and register your new IP address.
