Hello!
I already searched the forum and the web but didn’t find a clear statement on if/when/what to do - sorry if this is despite my search a duplicate.
I bought a Mango Router GL-MT300N-V2 to use it as a Wireguard Server so I can access my private Network from outside. The Mangobox is sitting behind a Fritzbox 7590 running the latest FritzOS 7.20 and - here’s the problem - a DS-Lite Connection due to a kind-of-cheap FTTH-Internetaccess. I did learn fast that VPN and all don’t work at all or only with a big effort using IPv4 on my DS-Lite connection BUT in fact I don’t really care about it because my Mobile-provider uses IPv6 too so I just could do the whole entry via IPv6 I thought. So in the Fritzbox I set the IPv6-portforwarding for Wireguard and: nothing. Only then I realized that the Mangobox doesn’t really use IPv6 - ok, I could have done that research before 
. The official GL.iNet twitter account announced the next Version to have decent IPv6-Settings on the interface but that post is from March 2020 and nothing seems to have changed so far.
Is there anything I can do to make my Mango Router use IPv6 behind the Fritzbox as Wireguard-VPN server? Install extra packages? Change configs? Or do I have to wipe everything and install a vanilla OpenWRT?
Thanks for your help!
