Sorry, I missed to give this information.. I've done every
step you've advised already.
iptables (the box is not that old :D) is completely empty,
telnetting _does_ work. isql or any other firebird-access
does not, though. nmap shows the port as open, when I scan
this specific port (nmap -p 3050, or nmap -p 3000-4000 or any
other range) but doesn't show it when running plain nmap <host>.

So it seems to be a firebird issue... is there any way to
track firebird's actions, like debug output or so?
I think I'll strace a bit.. I'll check in later if I have success :)

Thanks for your help,
