Dynamic DNS

Dynamic DNS (DDNS) enables you to access the firewall when it is provisioned with a dynamic IP address.

When the firewall receives a new IP address, it contacts the dynamic DNS service and updates the public DNS name with the new address. Using DDNS, the public DNS name always points to the correct IP address.

Note

We've discontinued Sophos DDNS. You can't register DDNS domains using myfirewall.co any longer. We recommend configuring a third-party DDNS provider.

Currently, we support the following third-party DDNS providers:

  • DynDNS
  • DynAccess
  • EasyDNS
  • ZoneEdit
  • Google DDNS
  • Namecheap
  • DNS-O-Matic
  • No-IP
  • FreeDNS
  • Cloudflare
