IPv6 through IPv4 VPN Tunnel

IPv6 through IPv4 VPN Tunnel with Palo Alto

The most common transition method for IPv6 (that is: how to enable IPv6 on a network that does not have a native IPv6 connection to the Internet) is a “6in4” tunnel. Other tunneling methods such as Teredo or SixXS are found on different literatures as well. However, another method that is not often explained is to tunnel the IPv6 packets through a normal VPN connection. For example, if the main office has a native IPv6 connection to the Internet as well as VPN connections to its remote offices, it is easy to bring IPv6 subnets to these stations. Here comes an example with two Palo Alto firewalls.
