This method no longer works for Videotron.
I will update this guide with a method compatible with the Helix router (in bridge mode) when I have one.
It should however be possible to adapt it for Hurricane Electric's free tunneling service.

2021 update:
A friend (Mezmenir) brewed me a new script:
Simply edit the values at the top as necessary. You can obtain the values you need on the Videotron 6RD Calculator.
Code: Select all
:local ipv4mask 0.3.255.255
:local ipv4relay 74.59.126.1

:local ipv6prefix [ :toip6 "2607:FA48:6DC0:0000::" ]

:local hex do={

:local b [ :tonum $2 ]

:local result ""
:for i from=0 to=($a - 1) step=4 do={
:set c (($b >> $i) & 0xF)
:set result ([ :pick "0123456789ABCDEF" $c ($c + 1) ] . $result)
}
:return $result

:set wanip $addr4
:set addr4 ($addr4 & $ipv4mask); # extract the relevant bits
:set addr4 ($addr4 << 4 ); # shift for prefix alignment

It's a lot of changes happening at the same time and if I can't make both v4/v6 coexist, I won't stick with fizz more than a month.
