What do you need to do that is beyond the built-in Windows firewall? My experience is additional firewalls/anti-virus isn't needed on Windows 7 and higher.

>I would like to know if some of you have used SoftEther open source free firewall for Windows, or if you ever heard of it. This is from Japan and it seems to do a good job. But, if there are red flags, I would certainly like to know about it. Any feedback on this would be greatly welcome.
