what is the difference between the port scan of the “Quick Test” and “Advanced Port Scanner”?
Why have different overall result?

#2

I get the same results independent of which test I use. However, my ISP ‘NATs’ my connection, so these results show the test against their Internet facing device, not mine. Regardless, the results are consistent.

Probably a couple of obvious questions:

  1. Is the IP address shown when performing the tests the same?
  2. What results do you get at another test, say shields-up?

yes it is the same.
2. What results do you get at another test, say shields-up?
all ports invisible.

Note: I did with the modem in bridge mode.
