Wifi > "..." > Turn On Wifi Hotspot... doesn't forward IPv6
Sorry, this might be the wrong issue tracker if whatever implements this behind the scenes is some other component, feel free to tell me where to forward this.
Anyway, going into GNOME Control Center and using Wifi
> "..."
> Turn On Wifi Hotspot...
gives me a wifi where every client connected has IPv4 only, while the actual host (where I set up the hot spot) has IPv6 internet just fine. I'm guessing maybe whatever software/code does the hotspot can't, or doesn't know how to, set up a separate prefix for the clients. But in that case, the fallback IMHO absolutely should be IPv6 NAT, not just no IPv6 at all. Yeah IPv6 is not meant to still require use of a NAT, but the more disastrous outcome is just being entirely cut off from that. So I think this is like a lesser of two evils situation, and just silently dropping IPv6 is not a desired default behavior in favor of IPv6 NAT.
Version: gnome-control-center 41.2 (as packaged by postmarketOS 21.12 based on Alpine 3.15.4)
Hardware: PinePhone 3GB Allwinner variant, so an ARM64 system not x64. (For the Wifi hotspot host, so where I enabled the hotspot.) The client in the hotspot is an x64 laptop with Fedora that usually accesses IPv6 connectivity just fine through other Wifi hotspots.
