Content filtering is the technique whereby content is blocked or allowed based on analysis of its content, rather than its source or other criteria. It is most widely used on the internet to filter email and web access.

What hardware do I need for two VLANs with content filtering?
Q. I'm setting up a new office building with cable internet access. There will be an area for customers to use wi-fi or patch in for internet access. I need to keep this separated from the office computers and also use content filtering on both. I was thinking I could set up two VLANs to keep them separate but then didn't know where to implement the content filtering. There will only be about 10 office computers and I don't imagine more than 2 customers using the internet access at any given time.

A. Michael The SnapGear SG565 will give you the VLAN separation you want with wired and wireless access. This is a small footprint, low-cost unit. For content filtering you can plug Webwasher into it. Regards Russ

Content Filtering Network Software?
Q. Anyone know of a free good content filter that will work for every computer on my network? I have 2 stationary computers, and 2 laptops that come and go. I am looking for a program that can be hosted on my Linksys WRT54G2 router or a single desktop that will still control all the computers. I can also work it out if the program can be hosted on a website. If you can help, that would be great! Thanks. P.S. ~ if you want more info, I can try to post it.
