Pfsense as 6rd border relay

[leeyc0]

I have a absurd cloud installation that still do not support IPv6, but we are now facing pressures demanding support IPv6. I am considering using existing pfsense as 6rd border relay and configure 6rd tunnel in every VM. Does pfsense support 6rd border relay feature?

(That is, we have a native IPv6 connection from our ISP, terminate at pfsense, and then pfsense encapsulates IPv6 traffic using 6rd and pass through IPv4 cloud infrastructure, then every VM will decapsulate the 6rd traffic to get a IPv6 connection. Upgrading cloud software stack is not an option either, as the developer apparently still do not have concrete plan on IPv6 support.)

Seems that 6rd border relay need patched stf :(
