Oh I do love these threads...

A port is either opened or closed. You can nat 'em, pat 'em, knock 'em, sock 'em but no matter what you do to them, they are either opened or closed.

That being said, from a port scan point of view. As a SysAdmin - I prefer closed ports.

When I'm wearing other hats, I would prefer open ports.

I love ports 80, 110, 443-5, 3306, 3334-3337. And all things UDP!
