(2019-10-14) Testing TCP Ports Through Your Firewall

Posted by Jorge on 2019-10-14


You need to test one or multiple ports through your firewall?

Then have a look at the following script, which has “built-in” templates for scenarios using specific TCP ports. You can use pre-defined template names, single port, multiple ports, range of ports. If you want you can add your own templates! Be careful with large ranges! Unfortunately, only TCP Ports are supported and UDP ports are not supported in this script.

Ohhh, and I almost forgot! You can download the script from here!

Cheers,
