Dynamic DNS

Dynamic DNS (DDNS) allows you to access the firewall when it's provisioned with a dynamic IP address. When the firewall receives a new IP address, it contacts the DDNS service and updates the public DNS name with the new address.

The firewall can be configured to use IP tunneling to access IPv4 services across an IPv6 infrastructure through a Virtual Network Enabler (VNE) provider. IPv6 VNE providers use IPv6 IP-over-Ethernet (IPoE) connectivity with IP tunneling.

Note

We discontinued Sophos DDNS. You can't register DDNS domains using myfirewall.co any longer.

IPv4 DDNS providers

We support the following IPv4 DDNS providers:

  • DynDNS
  • DynAccess
  • easyDNS
  • ZoneEdit
  • Google DDNS
  • Namecheap
  • DNS-O-Matic
  • No-IP

IPv6 VNE providers

The firewall supports Cross Pass (XPass) as an IPv6 VNE provider for Japan IPoE connectivity. XPass uses IPv4-over-IPv6 (4in6) IP tunneling to provide communication between IPv4 networks across an IPv6 infrastructure.
