Firewall Help - List of Ports I should close.

Can anyone tell me if a list of firewall ports that you should always close ?  My ports are currently marked as stelth which I assume is not the same thing.

Stealth is better than Closed - it won't even admit the port exists that way.

Still, it is better to Stealth or Close everything inbound unless you specifically need it open.

What Chris said.

I would set the firewall to stop ALL ports by default and then only open up the ports you need.

Under normal circumstances, unless you are hosting services inside your firewall then you don't need to allow ANY traffic inbound, except in response to a request from inside.

Both correct.  Trying to "block all bad ports" is an unrewarding lifetime career.  The only sane approach is to block everything by default, and then open the things you actually need.
