I have developed a connection protection system for Firebird 2.1+.
This is a sort way to check user connections and permit or reject these.

For example you can connect to database only XNET, or from localhost or
192.168.xxx addresses... or other enabled static IP address.


Please test it and send me ctitism and corrections.
