Use netcat for arbitrary TCP and UDP connections. It is dedicated for this purpose. It can also listen on a port.

nc -v 192.168.202.112 11053

Windows

Netcat implementation for Windows:

Note

Netcat can run as a server:

nc -l <port-number>

This is helpful for testing connectivity, e.g. to check if firewall rule is applied.

If that address was listening, and you had a path to it, your command telnet 192.168.202.112 11053 would connect just fine.

try to connect from the local machine (where this service is running) to this port - if that works you have a firewall "problem"
