Netsh

There are some good windows web proxies about. The only problem with them is they sometimes dont natively act as a transparent proxy. i.e. typically you’ll need to set your client machines to a specific IP and port.

I’ve used squid historically when setting up transparent proxies (mainly since it actually has a transparent mode) and this has worked well. Recently i thought i’d have a go at some of the windows solutions to see how they pan out.

Just wanted to note here that there is a tool for windows to ‘port forward’ Its a command MS ships that enables IPv6 to work on IPv4, but can be used as a port redirector…. so as long as you have IPv6 support on your box, you can do this.

syntax as follows;

netsh interface portproxy add v4tov4 listenport=443 connectaddress=targetmachine connectport=3389

so the machine above listens on 443 and redirects traffic to 3389 on targetmachine.
