Setting up an IPv6 tunnel via Hurricane Electric
Hurricane Electric is a major backbone and colocation provider based in the US. In addition to their hosting/transit services, they also host http://tunnelbroker.net, another free IPv6 tunnel provider, and http://ipv6.he.net/certification, a training and certificate site for learning about IPv6 networking.
Unlike AYIYA tunnels from SixXS, IPv6 tunnels from Hurricane Electric operate over IP protocol 41, which is defined by the IPv6 Encapsulation protocol (RFC2473). This is a separate protocol from ICMP, TCP and UDP.
The downside of this approach is that it does not operate over NAT firewalls natively. This may be an issue if your new firewall device is operating behind an ISP firewall with its own NAT. The ability to forward protocol 41 traffic to a machine behind the NAT is device specific and does not work on all firewalls.
