pcp and cgnat

[professor-jonny]

my connection is behind a cgnat and I'told my isp supports pcp for mapping ports so I am told.

Im not all sure how pcp works but do upnp requests get mapped and passed on upstream via pcp to my isp's router?

as my stock router upnp requests work but with miniupnp on my openwrt router upnp cant get a public ip and forcing an ip or using stun upnp still fails to operate.

miniupnpd doesn't not support nat on nat setups directly without specific configuration. please read #333

Thanks, I have read the thread and my problem is I have a config with cgnat >isp provided router nat on dmz> openwrt nat.

I am forced to use the isp's router in the middle because the sim card is taglocked to prevent use in unauthorised devices (phone use) as it is government subsided.

used the external IP option and the log indicates to me that I must change the upstream router to a full cone nat but it is in DMZ and I can't get past this issue.

The option of proxy support to redirect upnp upstream sounds like it should sort the problem, I look forward to this feature being implemented.
