You can block an URL by using the Proxyserver in RouterOS...
Or just block the IP's of a website by using the firewall filter in RouterOS, and just drop trafic to that IP.

create addresslist of sites that you want to block.
now add dst-nat where dst-addresslist is the addresslist of the block sites and and in action choose dst-nat in, to address put 127.0.0.1

or you can also do that using the firewall filter in RouterOS as mentioned by QpoX
or you can also do via webproxy
hth

Remember that you have to do setup of the webproxy. [and trasparent mode if you want]

After blocking the porn, sex sites in web proxy as indicated, i want a situation where anyone dat visits the forbidden site or blocked sites, it will display a custom message to the person.

ERROR: Forbidden

While trying to retrieve the URL http://www.google.com/search?q=xxx&ie=u ... =firefox-a:

* Access Denied.

Instead of displaying above, it will display like, please dont try such sits here, they will not open

Thanks fewi for your response,
are u saying that if i just put this string "please dont try such sites here, they will not open. Thanks" in the redirect-to , it will display it as I put it there.

I need at least a best option to achieve this. Fewi, You can pm at obinna4god@yahoo.com so that I can ask you some other things are relate to MT.

Thanks

No. As the manual clearly states you put a URL there. A URL is the kind of thing you would type into your browser address bar.

So the steps are:
1. Procure web server
2. Make website that displays whatever you want it to
3. Figure out URL to get to that website you created
4. Drop URL into proxy configuration

Hi,

I want to block the Porn Sites and other Ports then 80 only for hotspot users, can any one suggest how it is possible?? The same user id and password sholuld require to work when they connect with PPPoE Dialer and allow all website also, suggest how can we impliment the same


Nishit

Blocking lots of sites via the proxy is unfeasible.

Use OpenDNS for DNS, and set up the account to not permit adult sites.

Then destination NAT all Hotspot DNS traffic to OpenDNS, and let PPPoE users use 'full view' DNS servers so they have access to everything.
