Something I found online that could help people play online without opening any ports :
https://github.com/delthas/autopunch
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.
