This kind gentleman is running a simple website that allows you to test if outbound ports are open by listening to them. Very useful when you need to know if your ISP is blocking an outbound port you’re trying to use (like SMTP, port 25 for mail server outbound traffic for example).
Note the limitation (stated at the bottom of his page) about testing ports 22 and 25 via a browser because his server is using those ports. Use the other options to test those two ports.
