Description
For some unknown reason, pfSense does not ask in the GUI for local/remote IPv6 addresses when a user wants to use it to carry both, this is defined in [[https://tools.ietf.org/html/rfc7676]].
This should be addressed.

It may be in the RFC but have you confirmed that it actually works on FreeBSD?

I manually executed
/sbin/ifconfig gre0 inet6 <localV6> <remoteV6> prefixlen 128
In that case it should be fairly easy to add that to the GUI by splitting it into separate IPv4 and IPv6 options. It will need some upgrade code to separate out the existing IPv4 and IPv6 config into the new fields but that should be simple.
The same should be done to GIF as well

I have implemented the necessary changes for GRE interfaces (and tested them with my setup – seems to be working). I have no way of testing it for GIF and therefore hesitate to add my changes there, too. Should I still do it nevertheless or should I just create a PR for the GRE part? (PRs on Github are the correct way to submit the changes, right?)
