Hello,

I have made the necessary changes so miniupnpd listen for IPv6 packets
sent to PCP port (5351)
https://github.com/miniupnp/miniupnp/commit/ad88cc0819321eb2841958f846138ac3a225152f

There is still work to enable the "IPv6 firewall" and NAT64 PCP scenarios.
The PCP code was assuming the client want NAT44.

Regards,

Thomas

Dual-homed torrent clients? Dunno if they try to do IPv6 pcp?

Back to My Mac (Apple's auto-VPN for iCloud-enabled macs) is where most
of my miniupnpd registrations are coming from - I'm not sure if
recent-vintage OS X attempts PCP+IPv6, but it just might.  PCP looks
like a descendant of NAT-PMP, which Apple kit definitely uses.

Not that I can ever get BTMM to *work*, but I blame my iMac's flakey
wake-on-wireless-lan behavior for that.
