Welcome to /c/tumblr, a place for all your tumblr screenshots and news.

Our Rules:

  1. Keep it civil. We're all people here. Be respectful to one another.

  2. No sexism, racism, homophobia, transphobia or any other flavor of bigotry. I should not need to explain this one.

  3. Must be tumblr related. This one is kind of a given.

  4. Try not to repost anything posted within the past month. Beyond that, go for it. Not everyone is on every site all the time.

  5. No unnecessary negativity. Just because you don't like a thing doesn't mean that you need to spend the entire comment section complaining about said thing. Just downvote and move on.

The good thing is that you don't need to know which ports to block. You just set your firewall up to deny by default and then start whitelisting the things you want to allow.

Even easier if you put your "smart" devices in a separate network, then it's just:

  • Allow traffic from home net to Internet
  • allow traffic from home net to iot-net
  • drop the rest

Now you can surf the internet, control your devices and they can't phone home
