Photon always requires a server to be available to the clients. That could be in the same LAN but you will need a Windows machine to run the server. There is no hosting in the unity clients for Photon.
Unity Free does not export PUN Free to Android and iOS. The PUN+ package works around this limit and you can use the Photon Cloud for up to 100 concurrent players. No extra cost.
Hmmm, ok…
Anyway, i think i’ll start developing my game with the Unity Network and without a distinct server.
The issue with the NAT should not bother me since i’ll use the game only within a LAN.
And if i want to make my game online ready, i’ll use PUN+.
Converting my project to PUN+ in a later state of progress should not be the problem.
i hope…
