What do you need it for that it actually prevents? I've used this for close to a decade, and it has never broken anything. Sounds like FUD mate.

Ssh and p2p stuff are two examples off the top of my head. For p2p, you lose the ability for peers to initiate a connection with you if you block incoming traffic.

Why not block all incoming connections except on those ports?

That's what you usually do (preferably on your router if you are using one).

But the article says "and check Block all incoming connections". That's my point.

[konart]

I need it for... incoming connections obviously. P2P applications is the best example.

I second this.
