Ports used by on-prem HelpDesk

Question:

Besides TCP/80, are any other ports required to access HelpDesk through a firewall?

Answer:

In addition to TCP/80, the application may require the following:

1. Secure HTTP: If you install a TLS/SSL certificate, it uses TCP/443 or the port you configure for secure connections.
2. Email: The application checks email through IMAP or POP, so allow the required mail ports on your mail server.
3. Database: When hosted locally, the application connects to SQL Server to exchange data.

These are outbound connections, so no additional inbound ports need to be opened. These are the only ports the application requires.
