External Scan

Firewalla Outside Scan is a scan done from outside of your network to some of the well-known ports.  This is how hackers find ‘open’ ports and hack into your home network.

Ideally, this list should be empty, but if you do have open ports, make sure you know who opened the port and why.   Due to how the Internet protocol works, the scans are not absolutely perfect.

Who opened these ports?

1. Your router.
2. Devices inside of your network, such as NAS or PS4 via UPNP or NATPMP
3. You configured these ports to be open
