Server without port forwarding?

i’m using unity + photon. Is it possible to set up game that any player can create server(max 4 Player) on their pc and any other player can join without port forwarding or connect via program like hamachi (something similar to Left4Death or Payday2)? If is possible, how to set this and if is not, can player create server on something like photon server? How much cost something like that?

Photon uses their own servers so players don’t have to worry about port forwarding, you can find lot’s of tutorials on it just by going here. Their pricing plans vary but i believe that the free option is 20 ccu’s which is enough for anyone’s needs until they release the game, you can find more about the pricing here
