Load Balancing Not Happening for Pool Members of a Performance Layer VIP
I configured a Virtual Server as Layer 4 VIP with Load Balancing method configured as "Least Connections".
IP Traffic Flow is as below :
Client on Different Subnet >> 2.2.2.2:8001 >> F5 with SNAT Automap >> 2.2.2.4, 5 :8001.
During Testing we have seen that connections is not load balanced within 3 pool members. It just goes to 1 node not distributed within 3 nodes. I believe traffic is initiated from One Source during testing. But even if traffic is generated from 1 Source it will generate multiple connections or it is sessions . How to distribute multiple connections/sessions even it is generated from 1 node ?
Interestingly if from Source Application it by force closes the connection ( attached application image ) new connections then distributed to 3 backend nodes behind F5.
Please advise what could be done to distribute the tarffic within all 3 backend nodes.
