Third Party run my own server?PUN-Photon networking free

I dont want to use the photon cloud because 20 ccu(20 players world wide?) seems not that much. I have a server at home so i would like to run my program there instead of paying for more ccu on the photon cloud because i m just a student. Is this possible and have you got any guides for me?
Thanks in advance and sorry for my english.

 

I have to chuckle. Yes, 20 CCU worldwide are not much. But they are free
To host at home means your machine has to run 24/7. If you watch videos in your home network, that might affect your players. Just saying.
Follow this guide to setup your own Photon Server. We can't help a lot with firewalls and router configs. There are just too many variations. You can post any other questions in our forum in the Server section.
