There is also this : https://github.com/delthas/proxypunch that the developer said might be more suitable for PPSSPP.
Too bad its Windows only.
But maybe someone could look at the code and implement it directly into PPSSPP.
It would be useful for people that dont have UPNP on their router or dont want to mess with VPNs.

Actually a real PSP does support 2 kind of port forwarding/opening port, UPnP and STUN.
STUN is the one used by that autopunch/proxypunch, but STUN requires a server on the internet to test the port, while UPnP works locally on your router.

This might be better for simulating the STUN API on PSP https://github.com/NATTools/stunlib but will still requires a server, so at least one of the player will need to have UPnP/port forwarding support for the STUN server.
Anyway, STUN is a bit more complicated compared to port forwarding like UPnP because we can't decide which public port that will be used and requires a local port mapping (similar to portOffset + useOriginalPort settings).

Edit: Apparently there is a public STUN server, so we can use that instead of hosting our own STUN server http://stunprotocol.org/

Known public STUN/TURN Servers:
