How do you check if firewall is blocking a port in Linux?
You can check if a process listens on a TCP or UDP port with netstat -tuplen . To check whether some ports are accessible from the outside (this is probably what you want) you can use a port scanner like Nmap from another system. Running Nmap on the same host you want to check is quite useless for your purpose.

Checking Windows Firewall for blocked ports
- Launch Command Prompt.
- Run netstat -a -n.
- Check to see if the specific port is listed. If it is, then it means that the server is listening on that port.
