Most effective way to block outgoing traffic

  • Hi guys.

    This may be an amateur question but I'm new to pfSense.  We've heard that pretty much all the smart TVs spy on our viewing habits (even listening in to capture keywords in conversations) for targeted advertising.  Even if you try turning off this option in the TV's menu settings, users have still detect outgoing traffic being shared with a variety of sites.  One way to block this would be to essentially block router traffic to these sites, but since sites can come and go I was thinking instead if its possible for pfSense to entirely block outgoing traffic from a specific MAC address.  If so, would there be a step by step guide available?

    Thank you in advance for any feedback.

  • add a static or fixed ip to your TV. block rule source=tv

  • LAYER 8 Netgate

    You probably want to pass local traffic then block traffic to any.

    Note that it probably has to make outbound connections to get updated guide info (more for an STB like a TiVo), or get updates, etc.

    You will also need to make outbound connections to stream netflix, amazon, etc.

    The best thing to do is figure out if your TV is spying on you and return it if so.  They will only hear one thing.

  • Just remember, you don't block data leaving an interface, you block data entering an interface. Make sure you block your undesired data from entering the firewall in the first place.
