I've been working on this a little on and off and generally I'm stuck with IPv4 hosts only as accessible with the RPI only bridging over IPv6 as a transparent means of access.
I'm looking at completely replacing the RPI with a different SBC and seeing what I essentially need,
however it looks like I'll have my sam440 relegated to being LAN isolated.
As the ISP I use has changed (NTT FTTH Broadband replacing the older VDSL from Jupiter Communications),
this has also changed the IPv6 requirements from "possibly in the future" to "I am using this now".
So if any IPv6 (hell... bsdsocket.library as IPv4 stack Interface front-end, and other libraries for actual network stack operations?) solutions can be made to work natively, I think that would be preferred?.
Can this be queued up as a "want to have" for when any developer can get to it and make it happen?.
