How do I set up dynamic DNS?
A dynamic DNS service makes sure that the IP address attached to your domain name changes when your ISP gives your Firebox a new IP address.
You can register the external IP address of the Firebox with one of these dynamic Domain Name Server (DNS) service providers:
Dyn.com offers tiered pricing. The other providers are free. WatchGuard is not affiliated with these providers. No other dynamic DNS providers are supported.
NOTE: Dyn.com is the only supported dynamic DNS provider in Fireware v12.1 and lower.
Configure the Firebox to use Dynamic DNS
Before you configure the Firebox for dynamic DNS, you must create an account on your service provider's website and set up at least one DNS server. For instructions, see the documentation from your provider.
In Fireware v11.12.2 and higher, you can select to have the service provider use the IP address from your router or NAT device instead of the IP address of the external interface on your Firebox. For example, you might want to select this option if the external interface of your Firebox has an IP address in a private range.
