These are general recommendations for firewall port settings for versions up to and including 3.11.10:
Please ensure that traffic is allowed on the following ports both
a. Incoming on the server and
b. Outgoing on the workstation (normally allowed by default)
- 10880/UDP is used for discovery (even if you configure the API server to listen on another port) (spired.exe)
- 10880/TCP (or as configured on installation) is running the Spire API server needed by Spire Desktop and Spire Web (spired.exe)
- 5432/TCP for PostgreSQL communication (postgresql.exe)
