Idle TCP Timeout of non-vs handled traffic, F5(10.2.3)

Traffic originating from host behind F5 (10.2.3), F5 is the default gateway, with long idle times, are being timed out at 300 seconds.

 

Changing the idle timeout at "Local Traffic ›› Profiles : Protocol : TCP ›› tcp" does not effect no vs handled traffic.

 

Where do I change the global isle TCP timeout value for non-vs handled traffic?

      this is a server segment behind the F5. 10.64.7.0/24. The Self IP of the F5 is 10.64.7.1. The Application server initiating the connection out to a host on the other side of the F5 is 10.64.7.174. Source : 10.64.7.174 Destination: 10.250.96.24 TCP/1521 Network 10.250.96.0/24 is a firewalled database segment. Firewall timeouts are as follows: timeout conn 1:00:00 half-closed 0:10:00 udp 0:02:00 icmp 0:00:02 Conn is 60 mins (3600 sec), half-closed is 10 min (600 sec). The idle connection is timing out at 300 seconds. That is why I am looking at the F5 idle timeouts. This

    Don't you have a forwarding virtual server in place for the gateway?

    I ask the same question as kunjan... Don't you have a forwarding virtual server in place for the gateway?

     

    if you use a forwarding virtual server, the profile you must change is the fastl4 profile (or create a new one and change timeout value)

    Thank You for your response. I found the Global IP forwarding vs. I did not want to change the global foward-all so I created a new forwarding vs to match just the destination subnet, tcp/1521, and source subnet with an increase idle timeout setting. We will have to monitor to see if it works for us.
