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.

  • Why did you select that switch to do what you seek? I don't see URL filtering as an option.

  • Because i can take one. Tell me if there is any other solutions. Jul 27, 2013 at 22:38
  • Some devices can, but those devices shouldn't be called "switches", which name implies layer 2 not layer 7.

  • @tylerl what type of devices can do it? Jul 20, 2014 at 19:10
  • This sounds like an X-Y problem. What are you actually trying to do? A question like "How can I block sites and domains on a home network" will get you lots of options. Sep 6, 2018 at 18:28

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.
