How do I find my proxy IP?

I am using the proxy of my university.

address so that I can use it in my computer. Is there any tool or website to help me find it?

What you are looking for is called a proxy address, or proxy IP. You can try to use Google and type "proxy IP address".

It's very possible that Google has no information on this, but maybe some other sites have a lot of information on this. You can use a proxy detection tool like this one.

How do I check my proxy and firewall settings?

I would recommend you use the Windows built-in command line tool nbtstat, rather than opening a separate console.

You can see which network connections your PC has to the internet by issuing: netstat -an The "-n" option will show you only the connections currently active. The "-h" option will show you the IP address your PC is listening on.

The firewall and proxy settings are in the registry (HKLMSOFTWAREMicrosoftWindows NTCurrentVersionNetwork ListeningFirewall). There are several entries, including HKEYLOCALMACHINESOFTWAREMicrosoftWindows NTCurrentVersionNetwork ListeningProxy and HKEYLOCALMACHINESOFTWAREMicrosoftWindows NTCurrentVersionNetwork ListeningCustom. The values of interest to you will be different if your PC is configured as a relay for a VPN or not. The key names are the same as those you might see with an appropriate tool (pfctl, etc.) on Linux, though I don't know of any Windows-specific tools for examining these keys.

The values you want to examine will be listed as "Enable", or "Disabled". I recommend you run an NMap scan and look for open ports. If you can ping the hostname that you're looking for (eg ''), then you probably have no firewall or proxy issues. If you can't ping it, then you'll have to dig deeper to figure out what's blocking you.
