Priority: Normal Milestone: 3.00
Component: libtransmission Version: 2.80

PCP defined in RFC 6887 is a successor of NATPMP for controlling port mappings on NAT devices. In an attachment, I'm providing a patch implementing a PCP by integrating libpcp library.

PCP patch

comment:1 Changed 8 years ago by livings124

Looks like this will be maintained by miniupnp.

comment:2 Changed 8 years ago by livings124

ptatrai: are you going to be submitting code upstream for this to be integrated into miniupnp's client code?

comment:4 Changed 8 years ago by ptatrai

No, that pull request was only for PCP server implementation, which was integrated into miniupnpd daemon. This was merged today into upstream repository. The client code is different and it will be maintained separately in libpcp/pcp repository. In the future, libpcp could support NATPMP and therefore use of natpmp.c from miniupnpc could be replaced only by libpcp.

If you are still interested, I have added a newer version of the patch as a new attachment. It includes updated version of PCP library and also has NATPMP support.
