What is the best free solution to provide access to only a select set of websites like a white list. Our office currently uses a WebRamp (RampNetworks was purchased by Nokia and later shut down). It is limited to 255 allowed addresses. I was looking at using IPCop with the URL Filter add on. I'm comfortable with installing a router package like those and M0n0wall, but probably wouldn't make it through manually configuring Squid or the like. Thoughts on Redwall fireall, pfSense, Smoothwall? Any insight would be great. Thanks.
