Welcome to the Seven Forums.

There should be a way to do what you want using the native Windows firewall, but before I spend time looking into it for you --- could you please tell me why you want to do this? What apps do you expect to still work online if you do this?

You could always do it on the hardware side. My router, as well as many others I've seen, allows port blocking in the admin interface.

It does but Windows will cease to operate. The only function port 53 is used for is to resolve DNS names. No other communications will occur so Windows will be dead in the water.

Well, I'm not going to tell you how to do it. That's silly. It's like handing you a loaded gun.

Just know that you don't want to do it.

Your reply did not answer my two questions.

1) Could you please tell me why you want to do this?

2) What apps do you expect to still work online if you do this?
