GFI lan guard is a port scanner and vulnerability tester.

Therefore you would typically run a program like this on a computer on the outside of the network, such as from another location over the Internet.

In some cases a port scanner/vulnerability tester is used on the inside (trusted) local network, but that is not as common, and not as useful, in most cases.

The outcome will vary. In the case of a standard out-of-the-box home router/firewall, most likely all ports will be closed, meaning that no unsolicited inbound traffic will be allowed. Further, a vulnerability scanner is not likely to reveal any issues with the OS of the firewall router.

On the other hand, if you have an old Windows NT server that you are using as a firewall, and you have 20 inbound different ports open, then the application would report on multiple OS vulnerabilities and also tell you about all the open ports.
