Idle timeout and/or session-timeout options for ROS4.1

Am fairly new to ROS but not new to Linux and pppd options.

Based on some digging the idle-timeout and session-timeout options were available back in the ROS 2.x days.

How does one achieve this functionality with more recent versions of RouterOS?

I’m trying to get a USB stick to drop the connection after 30 mins of no activity.

Thanks in advance

:confused:

both idle-timeout and session-timeout are available in PPP Profiles
