I am using broadband connection in my home. I have "Tenda F3 300Mbps" router. I want to block all the porn websites or sexual content in the devices which is connected to my router through wifi.

I had block the porn content in my computer using the Open DNS proxy

208.67.222.123 
208.67.220.123

Now I want to block same thing in the devices which is connected though my wifi. How can I do this? I had made the changes instructed below, but it does not work.

  • This is a weak question. Google shows the answer, and I assume you looked there first. So what have you tried and what worked? Dec 11, 2016 at 5:10
  • I had tried to block these websites by changing the settings in the router but that does not worked for me & it is not an weak question, don't you know the answer Dec 11, 2016 at 5:12

    Change the router DNS to the Open DNS proxy addresses.

    If you can ever figure out a way to actually block all porn then you'll have money thrown at you. Figuring out what the actual content of a page is for a machine is currently beyond our machine intelligence capability. There are black lists of known sites but new sites crop up all the time and machines don't just "know" they're porn.

As was mentioned in a comment, changing the router's DNS to the OpenDNS DNS servers will work. OpenDNS has a handy how-to and allows you to choose what types of content to block for requests from your network.

HOWEVER, this only blocks access for those devices using the network's provided DNS servers, and you can get around it by simply changing the device's DNS settings to a unblocked DNS service.

UPDATE: Found Tenda F3 300 DNS Change How-To

I found this with some simple googling: http://setuprouter.com/router/tenda/w300d/dns.htm

Assuming it is correct you:

  1. Get your OpenDNS account set up and get the DNS information from them.
  2. Login to the Tenda F3 Router interface.
  3. Click on Network at the top of the page.
  4. Click on DHCP on the left side of the page.
  5. Click on DHCP Server on the left side of the page.
  6. Enter the OpenDNS DNS servers into the Primary DNS and Secondary DNS fields on the page.
  7. Click Save.

Any devices connected to the network will need to be rebooted or disconnected and reconnected to the network in order to pick up the new settings.

UPDATE

Go to the OpenDNS test page https://www.opendns.com/welcome/

If it shows you a large red X and says that you are not yet using OpenDNS, then you have not yet set up your network correctly and you need to go through the previous steps again or give us more information than you have so far.

If the page tells you that OpenDNS is working correctly then you have set up your network correctly and if you are still seeing sites you do not wish to see then, as I have stated several times so far, you must login to OpenDNS and follow their instructions for setting up your account to block the desired types of content.

  • I don't have a map of the Tenda F3's menus. OpenDNS does have a how-to that covers most routers. You'll typically find DNS settings on your router in the Networking section, but you may need to consult Tenda support to make sure you're putting the information in the correct place.
