Thanks for Thomas and Dimitry! I will try to change DummyPacketInterval to 60 tomorrow and to see what it will go on.

This has nothing to do with DNS. You could adjust this idle period in your firewall, however it impossible to control the firewall of clients. A solution is to use a disconnected model or send dummy requests from the applications to keep the connection active. Perhaps this link https://www.ibphoenix.com/resources/documents/how_to/doc_104 from a quick search provides another solution.

When application connects DB inside same network, everything works fine. When application connects DB through Internet (using Dynu DDNS service), connection may lose if there is not operation after period. I have checked firebird.conf and still not sure which parameter can avoid this issue. Or this issue is caused from Ubuntu ddclient DDNS service? Please give any advice to help me. Thanks.
