Just to reiterate the last comment, is there any plans to merge this into 14? There's appears to be a collection of bugs right now including in upnpd that would at least be partially resolved by having Full Cone NAT available in PF. This is interfering with our deployment of Tailscale in production behind PF firewalls. Is there something I could do to help encouraging some to pick this up and merge it in? Additional sponsorship from Sonic to support Tailscale's efforts here may be possible as well.
