In the event of troubleshooting by Forcepoint support, a telnet check may be recommended, but results in the following error:
"‘telnet’ is not recognized as an internal or external command, operable program"
Forcepoint software requires certain ports to be open in order for its services to function properly. If not properly set, connectivity issues with the SQL server or deployment errors may occur.
Forcepoint uses the ports located in the below articles for connectivity between its components. In the case of firewall changes or other events in the environment, these ports may mistakenly become blocked.
The Telnet tool on Windows servers can be used to test port connectivity.
