Dear sir/madam,

I am testing Firebird 3.0 in Ubuntu as DB Server.

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.

Best regards,

James
