PUN Classic (v1), PUN 2 and Bolt are in maintenance mode. PUN 2 will support Unity 2019 to 2022, but no new features will be added. Of course all your PUN & Bolt projects will continue to work and run with the known performance in the future.
For any upcoming or new projects: please switch to Photon Fusion or Quantum.
Port Numbers
Photon Cloud
In most cases you don't have to think about port numbers, as the client SDKs use a default port to reach the Photon Cloud Name Servers.
Every time a Photon server forwards a client to another server, the assigned address includes the port. This means that the port number of the Name Server is the most important one as this is not fetched.
Port numbers are specific per transport protocol and often per server type. For reference, the table below lists commonly used ports for Photon. These are available on the Photon Cloud.
Default Ports by Protocol and Purpose
| Port Number | Protocol | Purpose |
|---|---|---|
| OS Self Assigned Port | UDP | Communication port of the Peer. |
| 5058 or 27000 | UDP | Client to Nameserver (UDP) |
| 5055 or 27001 | UDP | Client to Master Server (UDP) |
| 5056 or 27002 | UDP | Client to Game Server (UDP) |
| 4533 | TCP | Client to Nameserver (TCP) |
| 4530 | TCP | Client to Master Server (TCP) |
