The op25 code is sending UDP packets to 224.0.0.1 which probably should
show up on your primary external interface.

You should be able to capture on your that interface (e.g. eth0 or
wlan0) or on your loopback interface (e.g. lo) in Wireshark. If you
can't, you have a Wireshark problem (maybe permissions?).
