You could have used it before with a gif tunnel. That's the way I've been doing 6rd on vanilla FreeBSD without any 6rd support.

edit:

Here's what you put in rc.conf

  cloned_interfaces="gif0"
  ipv6_activate_all_interfaces="YES"
  ifconfig_gif0="tunnel $MYIPv4 $THEIRIPv4"
  ifconfig_gif0_ipv6="inet6 alias $MYIPv6 $THEIRIPv6 prefixlen 128"
  ipv6_defaultrouter="$THEIRIPv6 -mtu 1280"


Great! Thanks!


This does have one limitation -- you cannot reach other IPv6 addresses also using the same 6rd gateway. It just doesn't work without handling the full 6rd protocol. But if you just want IPv6 to the wider internet and don't care about connecting to other users on your ISP over v6 this is a reasonable solution.
