Add a dynamic DNS provider

Sophos Firewall supports third-party dynamic DNS (DDNS) providers.

To add a dynamic DNS provider, do as follows:

1. Go to Network > Dynamic DNS and click Add.

2. Enter the hostname you received when you registered with your DDNS service provider using the following format:

   <accountname>.<DDNS provider>.com

   Some providers may use a different format. For example, you may need to specify the domain and subdomains for some providers and use just the domain as a sign-in name. Check with your DDNS provider.

   Note

   We're discontinuing Sophos DDNS in 18.5 MR1 and later. You can't register DDNS domains using myfirewall.co any longer.

3. Select an interface. Its IP address is bound to the hostname you've specified.

4. Select the IPv4 address of the interface.

   • Use port IP: IP address of the interface.
   • NATed public IP: Translated IP address of the interface. Use this if your firewall is behind a router and uses a private IP address.

   Note

   Sophos Firewall checks for a change in the server IP address every 5 minutes.

5. Select the third-party DDNS provider from the Service provider drop-down list.

6. Enter the Login name and Password based on your provider.

   If your provider doesn't require a username you must enter your domain for the Login name.
