How do I configure an idle connection timeout with Ubuntu firewall ?
I am encountering an issue in my production environment and suspect that the idle connection timeout in the firewall is causing it. To prove it, I need to simulate this in my local environment.
I have two local Ubuntu machines. On one of them I turned on ufw, configured a certain port to be accessed and connected to it from the second machine. After waiting over an hour realized that one hour is not the default idle connection timeout.
