Trying this from a real outside network will have to wait until
saturday, but trying it from an inside machine it seems that DNS does
its job and sends the packets to the right place. I get:
Your connection is not secure
The owner of <domain>.freedombox.rocks has configured their website
improperly. To protect your information from being stolen, Firefox has
not connected to this website.
This site uses HTTP Strict Transport Security (HSTS) to specify that
Firefox only connect to it securely. As a result, it is not possible to
add an exception for this certificate.

This address is the same one that ifconfig reports on the freedombox for
the ppp0 interface, which is the outside interface. So it seems to be

No. The ppp connection is the outside interface, via a CDMA phone.

I'll keep digging into the iptables rules. I have a lot to learn in
this area so it might take a while.

I'm running wireshark on the machine that has the wifi interface to
which the android phone connects (wlan0) and capturing the packets of
that interface. This android phone is not the same one I use to connect
to the internet via ppp.
I'm also learning the many options of wireshark and I'm quite
overwhelmed by the amount of packets wireshark is displaying. I've
tried to restrict what gets displayed to what comes/goes from/to the
android phone (static IP address), but I'm still getting flooded with
