Azure Load Balancer multiple frontend

Question

Hi,

I have one question related to ILB. We have configured three different frontend Ips and two back end with same VMS.

It is possible to create two rules that points to the same listener ports on two frontend addresses?

Thanks

@alsavi1984 , Azure Load Balancer provides the flexibility to reuse the frontend port across multiple frontends regardless of the rule type used. Additionally, some application scenarios prefer or require the same port to be used by multiple application instances on a single VM in the backend pool. If you want to reuse the backend port across multiple rules, you must enable Floating IP in the rule definition.

Note: Floating IP is not currently supported on secondary IP configurations for Internal Load Balancing scenarios.
