portquiz.net: Outgoing port tester

Outgoing port tester

This server listens on all TCP ports, allowing you to test any outbound TCP port.
You have reached this page on port 80.
Your network allows you to use this port. (Assuming that your network is not doing advanced traffic filtering.)
Network service: http
Your outgoing IP:

Test a port using your browser

In your browser address bar: http://portquiz.net:XXXX

I got complains that portquiz is not working on port 445. My hosting company OVH is probably blocking this port. Sorry about that. Feel free to contact them. See my blog post and OVH forum post (french).

Your browser can block network ports normally used for purposes other than Web browsing. In this case you should use the telnet or netcat commands to test the port.

Please also note that this server uses some port for real services (22, 25), so testing with your browser on those ports will not work.
