Round Robin issues for proxy base clients

HI, i am new for F5 LTM and i a have created a VS and Pool with 4-Mambers, but i am getting Round Robin issues when user want to access this VS, actually i have a Proxy envirnment in my organigation so due to this all user coming through Proxy IP .. when i am checking connection table for pool so client IP address is showing proxy IP address and traffic is only hit member-1 not other members.

  • Hi Vinay85,

     

    your observed behavior is most likely caused by an Source-IP Session Persistence profile.

     

    When using such a persistence profile, then only the very first request of a given Source IP Address would become load balanced according to your selected load balancing algorythm. Subsequent request comming from the same Source-IP (aka. different client behind the same proxy), would then just stick to the same pool member.

     

    If you need persistence for your application to work, you could experiment with the Cookie-Persistent profiles. In this case each individual client would become load balanced, but then stick to its initial node on subsequent requests (using an HTTP cookie)

     

    Cheers, Kai

     

  • Thasnks Kai..... so mean to say i need to remove Source-IP session Persistency after that it will be load-balance between Pool-members wuth round-Robin algorithm...???

      You should give it a try to fix the uneven load distribution. But keep in mind, that disabling/changing persistency profiles may break your application. So better test those changes before going live... ;-)
