luci-app-upnp: IPv6 pinholes aren't displayed

Powered by LuCI openwrt-19.07 branch (git-21.189.23240-7b931da) / OpenWrt 19.07.7 r11306-c4a6851c72 luci-app-upnp git-21.189.23240-7b931da-1 miniupnpd 2.2.0-4 miniupnpc 2.1.20190408-2 (on router)

I’m not sure if this is a problem with the luci app, a limitation of miniupnpd or that Transmission isn’t setting pinholes, or a limitation of miniupnpc for which it has no method of getting a pinhole listing.

I guess what I need is help trying to debug whether pinholing is working at all

Transmission needs a new feature and we need a way to view IGDv2 pinholes. Also here

One step closer. I see this in syslog, so I know we are compiled for IPv6.

Sun Jul 18 12:19:58 2021 daemon.notice miniupnpd[19100]: HTTP IPv6 address given to control points : [2602:306:xxxx:xxxx::1]

And now upnpc sees the upnp daemon and sets the pinhole.

The problem for me was two global-scope v6 address blocks on the interface. I can’t set a pinhole from one to the other.
