Not sure which port they scan to allow them on the inside of the firewall.

The only outbound ports open without concern are 123(UDP), 53(UDP),

If I read this, this would go around my guards, as they are
"piggybacking" on 443 in and out, right?
Thanks,

I'm really not having a big concern since I have 2 firewalls
anyway. I
have a firewall on one device and a firewall on my computer. So
the only
ports they will see is the one on my first device and not the
computer.
At least that's my theory.
