cutting off all sorts of "p o r n" on 877 router

Unanswered Question
Jul 17th, 2010


Can anyone give me a tip on creating firewall rules to ideally cut off any kind of porn access or at least significantly limiting and making it difficult?

Thank you!

I have this problem too.

Oh, this is ridiculous! We are in a router support forum and they are censoring the word which is the reason most firewalls exist.

My post is about P O R N and getting rid of it, how on Earth can I ask question if the word is censored?

here are some options:

1- using AAA or Tacacas authentication servers for access.

2- limiting the Access to specific source IPs.

3- create different user privileges.

1- using AAA or Tacacas authentication servers for access.

And how exactly ???

2-  limiting the Access to specific source IPs.

So people will start changing their IP addresses

3- create different  user privileges.

Like how exactly ?

What I misunderstood here?

That all the OP wants, is to cut off user'.s access to "questionable content".

Open DNS works great for us at our  small school.

Check for kids using IP addresses instead

But go on! What commands should I issue to the router to disallow access to pornographic web sites and d/ling porn via p2p and bittorents?

Hello Zen,

You have few different ways of doing it.

1. Use a URL filter like WebSense on N2H2.The router will redirect URL request to the URL Filter server and server will approve/reject the request. Based on that the router will either forward the request to the internet or send a deny page.

2. Use a content filtering solution which is more granular and will look for any offensive content and block it. You need a content filter module either installed on the router or you need to have a third-party solution

3. Use a proxy to access internet. Configure proxy with parental controls. This could be somewhat economical given that there are some implementations that could be run on a linux box. But the only problem with this solution will be scalability and reliability.

Hope this helps.

I know its a problem being sensitive to each word, I shouldnt be .. and I have also been over stressed a bit.

So I apologize, I do much respect you!!

Mohamad, you are wrong. The OP was perfectly clear in his post, but your answer was not addressing the problem, and I simply remarked that.

All the rest is unnecessary rambling by your side, that you could have spared. Thank you however for providing the link to content URL filtering.

I personally have no bad feelings, so take care.

Hi Paolo,

what I understood the poster needs to limit access credential to the router being accessed by everyone, the word (P O R N) access what made me assumes this.

What I misunderstood here?

I was waiting for your answer, and you didnt mention any thing in detailed explanation, However, I was also waiting for the Original poster to understand his delima as HIS QUESTION WASNT CLEAR.

I was actually very surprised about your offensive reply and abusement, but I have decided to better send you this message rahter than any thing else. Kindly read the following points carefully:-

1- Its me who will decide to refrain from posting not any body else.

2- I beleive it would be more elegant and polite to describe the Original poster question and solution to all of us including me since you know it rather than being offensive.

3- I will not report your previous post as abusing cause I found it sufficient writing those points for you so you would learn from your mistake.

To the Original Poster and ALL :

Please refer to (Cisco IOS Content filtering) in this URL which  should solve your problem, However, be informed that it requires licensing and additional payment. here is the url:

Thanks for reading,
