In CSS can I configure to always use some particular server for a given subnet.

Lets say users on subnet 172.16.1.x will use server1 and users on subnet 172.16.2.x will always use server2 behind the CSS.


The idea is to fulfill the request of a particular user through a particular server always .

The CSS services are transitioning for the ports used for class A keepalives are getting stuck in the wrong state, and therefore the CSS is leaking ports.

Engineering update:

The CSS is processing a FIN received from the server at the same time as the connection is being closed for a class A keepalive. There is a race condition possible in this scenario that could cause the port to become stuck in the wrong state if the connection is closed before the FIN is finished being processed. We now make sure that the FIN state transition is processed before

the connection is cleared.


A workaround for this issue would be to have the server configured to not send a FIN back to the CSS for class A keepalives.
