F5 VIP issue while accessing from one of pool member
Hi - I am facing below issue in one of my application: Setup - Its a windows application running on a 4 node cluster. servers are behind a F5 VIP. Application is secured with Active directory authentication. Application works fine if i access it form from user VLAN. But not when I access it one of cluster node. Issue - When I access application using VIP from one of node it keeps asking for authentication and works after 4-5 attempts. But when I access application using sevrer's FQDN from the server it works fine.
To test I disabled a node in F5 pool, then accessed the application from that node and it worked.
So it looks like if a request is coming a sevrer A and if F5 is directing that request back to Server A behind VIP, its not working but it works if F5 is directing that request to any other pool member.
Is it normal behavior of F5, if it was I am missing.
Please let me know if you need more information to help me out on this.
Thanks, Ravi
