NimbostratusFloating Ip Problem
Hi
When I assign a floating IP, ALL CONNECTİONS DROP.
I have BIG-IP devices running in HA mode in a VMware environment.
When I assign a floating IP, all connections drop.
But when I remove the floating IP, everything starts working again.
What could be causing this issue?
there is distributed switch and all three settings are Accept.

What state are the BIG-IPs in when you configure the floating IPs on each interface other than the management interface? I would go through the following article and ensure you have configured everything required.

Have you allowed traffic on you FWs from the floating IP to the pool members?
mbabacanYes, we are not experiencing this issue with our other customers. The floating IPs are allowed, and when the floating IPs are translated to local IPs, the issue disappears. The problem starts only when using floating IPs. Also, the problematic floating IP is not on the backend side, but on the frontend, where the self IP in the virtual server block is causing the issue.

Might you are reusing this IP somewhere else?
- mbabacan
No, all of these IPs are private. Additionally, we set up test VM F5s separate from the production environment and tested with new IPs, but the situation is still the same

Yes, we also applied the Mac Mascuarade as a test and the problem occurs again.
