I want to block some specific Urls and DNS addresses. I am thinking if i buy a manageable switch (More specific would be TLSF1024D) what can i do to block some sites, and specific urls like http://www.youtube.com/watch?v=fGH7NxSEGtA , that are not suitable for children.

Sorry for my bad English

Why did you select that switch to do what you seek? I don't see URL filtering as an option. –  schroeder Jul 26 '13 at 16:21
    
Because i can take one. Tell me if there is any other solutions. –  syed mohsin Jul 27 '13 at 22:38
    
Some devices can, but those devices shouldn't be called "switches", which name implies layer 2 not layer 7. –  tylerl Jul 27 '13 at 23:02

I think the short answer to this question is "no". Specifically switches work at layer 2. The content and data you're looking to block is at layer 3. A switch that's "managed" or "smart" typically means the switch can be managed remotely (command line or web UI) and configured to participate in STP, VLAN, flow control and other layer 2 stuff.

All that said current trends are for network hardware manufacturers to pack more and more stuff into the routing hardware. Some providers may be integrating some layer 3 functionality into their switches but the link you provide looks like a pretty basic switch to me.

What you need is an local Internet filter on your computer, a firewall, a router, or use an DNS filtering service like OpenDNS, which can block sites for you.

The switch you liked to says it is 'managed' but that means that you can configure it using its own internal website. 'Managed' does not mean that you can manage your URL traffic.

Switches are not what you need to be looking for, and there are free options of the above.

i am using openDNS for time but it only blocks whole site not specific urls of a site –  syed mohsin Jul 27 '13 at 22:37
