What port is my phone app using?

Posted 09 June 2016 - 10:38 AM

I have a phone app that connects flawlessly when my WiFi is turned off, but if I use my house WiFi it has connection issues.... How can I check to see which ports or whatever my phone app is trying to use so I can open them on my router?

I take it you didn't write this app yourself?

This is a very predictable issue, so the answer will typically be available somewhere already.
Most apps that listen on specific ports will list them somewhere on their FAQ page, or something. Or at least be happy to tell you if you contact them about it.

Failing that, you could use tools like nmap to do a simple port scan on your device. See what ports are accessible.

Hey there. Thanks. I have contacted the company via facebook and they have no idea. I did a bit of digging and found that their apps are written by other companies. So I've sent emails to those companies but we'll see if they respond.

Is "nmap" The name of the program or is it the "type" of software?
