Just wondering if anyone know that there're default firewall rules on the NF4V orcon white genius modem?

When I checked mine it's empty, yet when I do a scan on GRC ShieldsUP most of the ports are showing up being rejected out right.

I'm on UFB, so perhaps there's a firewall in the Chorus ONT?

Anyone know how these are all setup? And if possible, how to close all the ports as I can see many < 1024 ports are showing up as "closed" right now.

So it's responding to the outside...
