Overview:
- Sophos XG Firewall (SF) support four methods of IP tunneling to promote interoperability between IPv4 and IPv6 networks. IP Tunneling is a mechanism that encapsulates one network protocol as a payload for another network protocol; i.e. either an IPv6 packet is encapsulated into an IPv4 packet for communication between IPv6 enabled hosts/networks via an IPv4 network or vice-versa.

- Go to Network > Dynamic DNS and click Add.
