Vigil Learn › Your Wi-Fi And Router

Something is open to the internet. Is that bad?

Lesson 5 of 10 in Your Wi-Fi And Router

It means anyone online can reach something inside your home. Unless you set it up on purpose, close it: the fix steps in Vigil walk you through your router's settings.

Why It Matters

An open door to the internet lets anyone online try to reach a device in your home. Attackers use automated tools to look for these all the time.

What To Do

  1. Think about whether you set something up on purpose, like a game server or remote camera access.
  2. If not, follow the fix steps in Vigil for this item.
  3. In your router's settings, look for a section usually called Port Forwarding, Virtual Server or NAT, and remove entries you don't recognize.
  4. Turn off UPnP too, so devices can't quietly open new doors.
  5. Run the checkup again to make sure it's closed.
