SonicWall: Stealth Mode

I think there are some cases where some firewalls actually might make sense.  Im a big fan of Check Point and Palo Alto.  But in small office cases where they just need Internet and protection, I dont necessarily see anything wrong with other brands.  In a case I had recently, I have a small doctors office that just needs Internet, and nothing else.  A SonicWall was just fine for them and at a decent cost.

SonicWall does have this checkbox that I recommend for this very type of scenario.  Its the "Enable stealth mode" box.  See below.
