Content Filtration

If you are a business owner and you are tired of employees looking at things they shouldn't be, or downloading things they shouldn't be you will love this. If you are a good mother or father who want to shield their children from Drugs, Satan, and Rock and Roll then this is for you. To use the filtration feature of this router, you must have a subscription to the filter list; ZyXEL provides the first six months free, and from there out you are on your own. As you can see in red, "The Filter List has not been loaded". I clicked "Free" in the menu to register for my first free 6 month subscription to the filter service. You are basically paying for a list of sites that are downloaded and loaded to the router so it knows which domains to block... however, with the millions of sites going up PER DAY how effective will the content filtration system be?

Not only can you block all the categories but you can also block cookies, Java, ActiveX, and web proxies. Furthermore, you can chose what times of the day to block such categories, domain names, and custom sites that you put in yourself.

Here is all you need for registration.

Click on "List Update" and you are taken to this page. You can download the list and apply it, and even set it to auto-download for you at a specific date and time- yet another cool automatic feature this router presents.

Click on "Exempt Zone" and put in the port range for the bosses or parents; you guys still have full internet access if you want to worship Satan (especially the bosses).

Yet another cool option; you can block web URL's that contain keywords. This can be useful but USE DISCRETION! I was at an internet gazebo at the airport where you can pay to surf, and they had a bunch of words filtered... one being the word "Pee". Well, guess what... I couldn't browse www.sPEEdguide.net because of their moronic usage of a content filter, and I lost the $5 I paid to use it.

Along with downloading the filter list that is provided, you can also add domains you want to block or take domains out of the list that you want to trust. Do you really want to get strict with where your employees or kids (or even yourselves) can go online? Then check "disable all web traffic except for Trusted Domains".

Here is a look at the Content Filter Logs; They are empty, but they won't be for long. We have some content filter testing to do!

Content Filter Testing

I checked all the categories, added "warez" and "hard" as two of the words to filter for URLS, and went to Google. A preliminary search for warez brought up the obvious warez.com, which when I attempted to load the router quickly blocked. Next, I went to two sites that I know have the word "Hard" in them, Hardocp.com and Hardforum.com - both were also blocked quickly. When I say "blocked quickly", I mean there was no hesitation from the router, the pages loaded instantly with the simple text message "Please contact your network administrator!!"

Here are the filter results so far. They show the time, date, source IP and action taken by the router. We are 3 for 3 so far, let's see if the router can keep it up.

Anonymizer, a popular web proxy, and Gambling.com were blocked well enough... A few more tests of Porn sites yielded varying results, a few were blocked and a few others were not. A site on Sex Education showed up just fine, as shown below.

A search on satan led to a few million links on Google, a very large majority that I tested opened and loaded fine. The router did not do it's job in blocking them.

All in all, as I have previously mentioned, I believe the content list will always have it's flaws. At the pace the internet is growing, it is truly an impossible task to have a comprehensive list... EVER. I suggest you do your own testing with a combination of the content filtering list and keywords to your in your quest for a safe internet environment for your kids. As for employees, if you try to block entertainment, good luck. Some major sites may be blocked, but anything on the internet is deemed entertainment. If you have a specific task for them to do and ONLY do on the internet, I suggest you limit their browsing to the select few domains you want them to be able to reach.

Before I logged out of the Admin area, I made sure to make myself exempt from the Content Filtration and test that function, needless to say it worked.
