Hey Geo, you can download and run Network Utilities for free. The only thing that you can't do is actually forward a port with the PfConfig. You can launch PfConfig and see that it works on your computer, but it will not talk to your router. Many of our customers just want a single port forwarded so we can not offer any sort of trial in that respect.

I know that there are plenty of negative reviews on here, but that is such a tiny sampling of our customer base. Mostly only unhappy customers take the time to write a review. The happy customers don't have any reason to.

If you purchase Network Utilities and it does not work with your router then Allen will work with you to add support for your exact router model. If we can not make it work we'll refund your money. The only thing we ask is that if it does not work with your router please be patient while we figure it out. It can be difficult to troubleshoot someone's home network over the internet.
