Photon Server

PhotonControl automatically sets up the Windows Firewall to allow Photon Server to communicate on the network. If you don't use Photon Control, check out the Firewall Settings page for how to do so. Make sure all operating systems, firewalls and routers in your network are set up to allow traffic on the required ports as needed.

Define your own ports within the Photon Server configuration.

The table below contains the default ports configured per listener in PhotonServer.config as included in the SDK package.
