There are a couple of possibilities.

It is possible to configure Direwolf to gate traffic to the Internet. If
you did NOT touch the direwolf.conf file then you are most likely OK
since my scripts do not configure Direwolf to do this.

It is possible that you have configured Xastir to gate packets to the
Internet. In Xastir check Interface -> Interface control, select Device
0 Networked AGWPE, click on properties. Verify under 'IGate Options'
that 'Disable all IGate traffic' is selected.

You might have an application loaded on your RPi that broadcasts on all
network interfaces. Verify that iptables has the policy the install
scripts should have setup. Run script iptable-check.sh, you should see
these addresses are dropped 224.0.0.22, 224.0.0.251, 239.255.255.250

To understand your problem I would need to look at the offending packets
that your coordinator is referring to. For instance is he referring to
broadcast/multicast packets from some application or is he referring to
APRS packets gated to the Internet by you. You could ask your
coordinator to send you a copy of the packets they saw or you could
capture them yourself.

# From a console window
# Install tcpdump
apt-get update
apt-get install tcpdump

# Run tcpdump
sudo tcpdump -e -vvv -i wlan0

Hope this is helpful.
