To change the ports that the server listens to you will need to edit registry keys on the machine that the Repository Application Server is running on. See How to Specify Repository Ports - Server Side.

Client Side

On the client side, in ER/Studio Data Architect you can use the menu Repository > Repository Properties. Change to the Server tab page and specify the ports that the client communicates to. The register value RepoServer Port mentioned before corresponds to the Communication Port listed on the Server tab. The register value RepoProbe Port corresponds to the Identification Port listed on the Server tab.

The identification port uses a UDP broadcast to identify running Repository servers that can be connected to in order to provide a list to the user (for example, the list in the Repository > Options dialog). This is optional and should not cause any issues if it is unavailable.

The communication port provides all communication between the ER/Studio client and the Repository server services, such as login requests, get diagram requests, checkout/check-in requests, event updates, and any other operations requiring information from the Repository. All communication is initiated by the client via TCP/IP. This port is required for use of the Repository, although it can be changed to a different port number if necessary.

The TLS checkbox allows you to securely connect with the repository at port 54334 or another port of your choosing.
