Yup - looks like your UDP-Session is about to timeout.
1. Configure a custom application for your Camera Traffic (UDP Port 7028 from what i see on your screenshot):
applications {
application my-camera {
protocol udp;
source-port 0-65535;
destination-port 7028;
inactivity-timeout never;
}
set applications application my-camera protocol udp
set applications application my-camera source-port 0-65535
set applications application my-camera destination-port 7028
set applications application my-camera inactivity-timeout never
This will set the timeout to "never" - you also can define the number of Seconds like 100000 (set applications application my-camera inactivity-timeout 100000)
2. Configure a security policy to the junos-host zone and call the application
[edit security policies]
from-zone trust to-zone junos-host {
policy test {
match {
source-address any;
destination-address any;
application my-camera;
}
then {
permit;
}
}
}
That should fix your Problem.
