Jason Wharton and IBO don't have anything to do with your problem. It
would be pretty surprising if he replied to your email and gave you advice
on how to configure the firewall on a Linux server to accept event traffic.

Port 3050 must be open, since it is the default port on which the gds_db
service is listening for connections. The "secondary connection" refers to
the remote port that you must open in your firewall if you use events.

That won't help; or, if it does, it will be by chance. By default, the
server seeks a random port to use as the secondary (or "auxiliary") port
for event traffic. What you actually need to do is open a port in the
firewall AND configure the RemoteAuxPort in firebird.config. This is
documented in the firebird.config file itself and also (in detail) in the
Firebird 1.5 release notes.

No, with a firewall, leaving it to chance has *at best* a very small hope
of success.
