Windows Firewall - Rule created ports still not opemn

I've created basic inbound and outbound rules on Windows Firewall on a server that is off the domain - It runs an application which connects (on the localhost itself) using Port 48200, so I'm told anyway.

I have created the rules as attached (currently I'm onto All profiles, I initially started with Private) -  I get no successful telnet connection and a 'netstat -n -p tcp' for open ports does not show the server listening\established on that port. I have seen the below line in 'netstat -a -n' which indicates the port is blocked  - where have I gone wrong?

  TCP    ServerIP:51668    ServerIP:48200    SYN_SENT

Thanks

We have two instances of this application: one is listening on 48002
TCP    127.0.0.1:48002        0.0.0.0:0              LISTENING
 TCP    127.0.0.1:48002        127.0.0.1:50053        ESTABLISHED

But the second instance running on 48200 doesn't display any results - therefore are you saying that the troubleshooting isn't firewall based, as those rules come into play later, that it's an application issue?
Exactly.
Make sure your service is listening on ANY interface (0.0.0.0) or on the Ethernet interface.
Listening on localhost (127.0.0.1) only allows the local PC (the one the service is running on) to access your service.

Also make sure the ports and protocol match (48002/tcp or 48200/tcp)

Thanks for the answers - I've flagged it to the application team as an app issue rather than firewall - will see what they come back with.

We do only want it running on the local host as it's an app on the server itself.
