how CSS group command track the session info

Regarding setting up the ArrowPoint with Virtual IP Address (group command) for the 2 HA Machines: When the 2 HA Servers try to connect to a Port on an external Server, will the return traffic know how to route to the correct HA Server ?

Will it possible for the return traffic be routed to the wrongserver because of the load balancing and source IP being the same.

We have seveal connections between both HA servers and other server at the same time. If the source/destination IP and the destination port are the same, there is a chance when source port can be the same. So what will happen?

Re: how CSS group command track the session info

The group command changes the source port of the internal server initiating the connection. It creates a portmap table for the original source port. For more information on source groups and the base ports it uses see the advanced config guide:
