Of course, because instead of using unpredictable ports
for event communication you have specified to use 3050,
and this port is opened through the firewall, otherwise
you wouldn't be able to connect anyway.

Isn't that a very old story, that events can't be safely
used whenever a firewall comes into the playground?
