Issue Port issue in plesk firewall

Server operating system version

Ubuntu 22.04

Plesk version and microupdate number

Plesk 18

Hello,

i am trying to open Port 9007

My settings in plesk's firewall is like this



But port 9007 is still closed. What can be the issue?

Maybe a firewall in between is blocking it?

Maybe a firewall in between is blocking it?

I have installed UFW, then did sudo ufw allow 9007 and rebooted server.

Still the port is closed. So i think maybe plesk is not the problem in this case.

Maybe the strato (my vps provider) is blocking this port?

 

[MrPleskLearner]

I talked to strato and they say they don't block any ports. All ports are being managed by web server.

 

[MrPleskLearner]

I removed UFW. So there should be no firewall anymore on ubuntu. Or there is still something in ubuntu which regulates the ports?

I feel like there is a thing somewhere else which regulates the ports. Maybe it's the plesk? I am confused.

Okay, i found the solution by myself. Sorry for bothering you with my newbie questions. I am just using server just since some days

But with the hope that it can help someone... Ports are being regulated by apache (idk what's that actually). What i did is just added Listen 9007 to 000-default.conf



And then sudo service apache2 restart

That website for the port checker says the port 9007 is open but the script which i want to install says it is not. Because 000-default.conf can regulates the ip adress of my server only. So if i put myipadress:9007 then i can navigate to my default page. So port is for the ip open. But how can i open the ports for domains too?

 

[Peter Debik]

If a "port is open", it means that it can be addressed, traffic is not blocked. This does not mean that a service is reacting on the port. If a port is closed, a service could be actively waiting on traffic on that port, but as the port is blocked it cannot be reached. So what you mentioned above is that you told Apache to listen on port 9007. This does not necessarily mean that this port can be reached, because there could still be a blockade.

Your question how to open ports for domains is probably how to tell Apache to listen on specific ports for specific domains, right?
