I was wondering if anyone knows of an easy to configure proxy server . I have tried Squid on Ubuntu 10.04 and 10.10 and have never been able to get authentication working no matter what "how to" or front end I have used such as webmin.

It would seem that someone might have made an easy proxy server .ISO or virtual machine image.

I will be running this on a Virtual Machine on a server with Public IP in a data center. I want the proxy to not reveal the originating IP to web sites. Would be nice if it worked with Hulu. I would like to be able to set up accounts for family and friends. I am NOT looking for a proxy on my LAN.
Open to all suggestions

Thanks
