Allowing the port to flow through firewall has nothing to do with listening process. What process do you expect to answer? I'd check that it is configured correctly and is running.

This browser is no longer supported.
Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.
we are trying to open ports 6300 on Windows server 2019, we tried to add rules in
Windows Defender Firewall with Advanced Security -> Inbound Rules and Outbound rules, Edge Traversal is set as "Allow edge traversal"
the port 6300 is not list under netstat -an
when we tried to telnet, it failed with this error
The result is the same no matter we turn off or turn on the firewall ( Domain, Private, Public)
Anyone knows Is there any thing we missed in the setting? Thank you.

as we are preparing the environment for the installation of another product,
is that means we have to wait until the installation is done to see if the process is running on that port?
Yes, that's 100% correct. You could give this one a go.

thanks, will post the update when we are able to carry out further testing after the installation next week.
Hi,
Thank you for posting in Q&A!
There is a difference between having a process listening on the port and having the port allowed on the firewall.
1.If you set an inbound rule to allow connect port 6300, this port will be open.
2.When you use netstat -an command and telnet, only when there's application which are using port 6300, will show listening or telnet successfully.
Since you haven't installed the application used for port 6300, it's normal phenomenon that the port 6300 is not list under netstat -an& fail to telnet.
Hope you have a nice day : )
Gloria
