Add a dynamic DNS provider

The firewall supports third-party dynamic DNS (DDNS) providers.

1. Go to Network > Dynamic DNS and click Add.
   Restriction The firewall doesn't support DDNS in high-availability mode.
2. Type the hostname that you received when you registered with your DDNS service provider.

   For third-party service providers, use the format <accountname>.<provider>.com. Some providers may use a different format.

   Restriction We're discontinuing Sophos DDNS. You can't register DDNS domains using myfirewall.co any longer.
3. Select an interface.
   The IP address of the selected interface will be bound to the specified hostname.
4. Select the IPv4 address source.

   Option	Description
   Use port IP	Use the IP address of the selected port or interface.
   NATed public IP	Use the public IP address assigned to the selected port.

5. Specify the time interval that the firewall will use to check for changes to your server IP address.
   For example, if the interval is set to 10 minutes, the firewall will check for changes in your server IP address every 10 minutes.
6. Select the third-party service provider and enter the credentials.
7. Click Save.
