[j-nsp] Security-flow TCP idle timeout at SRX

[Robert Hass]

Hi

I have issue with one of our applications. We have two security zones: LAN
and Servers.  Computers from LAN are connecting to Servers to port TCP/2020
(it's CTI application).  Users reported that they have to re-logon due to
idle timeout - I checked security logs on SRX and sessions was disconnected
due to tcp idle-timeout which default is 30 minutes.  How I can increase
this timeout for connections TCP/2020 ?

Will below configuration will be sufficient :

security {
 policies {
  from-zone lan to-zone servers {
    policy 1 {
        match {
            source-address any;
            destination-address any;
            application any;
        }
        then {
            permit;
            log {
                session-init;
                session-close;
            }
            count;
        }
     }
  }
  from-zone servers to-zone lan {
    policy 1 {
        match {
            source-address any;
            destination-address any;
            application any;
        }
        then {
            permit;
            log {
                session-init;
                session-close;
            }
            count;
        }
      }
   }
 }
}
applications {
  application myapp {
    protocol tcp;
    destination-port 2020;
    inactivity-timeout 100000;
  }
}
