Hi, Gary. Thanks for the answer.

I don't know if i understood what you wrote, but the fact is that the
only way in can make events to work in my scenario is making my server
a DMZ, but this way i have all its ports exposed.

At this moment, i'm connected to the server from my home with an
application that is listening to events, my IP is 200.231.46.246 and
the server 'RemoteAuxPort' is set to 3060.

Look at this:

[root@linux1 firebird]# netstat -nap | grep 200.231.46.246
tcp 0 0 192.168.16.4:3050 200.231.46.246:1639
ESTABLISHED 28518/fb_inet_serve
tcp 0 0 192.168.16.4:32784 200.231.46.246:1640
ESTABLISHED 28518/fb_inet_serve

Why the second connetion is to the port 32784? Shouldn't it be 3060?

Regards,

Fabiano.
