PassPort is a simple port forwarding utility. The program runs as an NT Service and can forward various ports from any of local interfaces to whatever remote IP address. It is easily manageable with a simple Windows GUI.
Runs on MS Windows XP or newer.
Signed up just to say thanks and give a little feedback, I have been using this on XP for about 2 years to maintain part of PCI/DSS (credit card security) compliance in a restaurant. Central BBQ is small and we don't have much of an IT budget but his service allows me to let biz office workers get catering prices from our point of sale system through a secured machine that is the only network access to the "secured environment" I have recently upgraded to Windows 7 and the older MSI I had would not install on 7. I was bummed! Last edition will. Thanks for making the installer work with Win7 and assisting me to be compliant on Windows 7. The other alternative was POSready 2009 (XP that is not sunset) which for some reason had very poor network performance compared to real XP and Windows 7. All the other work arounds I came up with did not have the simplicity or natively run as a service. I am able to task schedule the service on and off during office hours which adds another layer of security.
