Ask about CWMS 2.0 IRP Design

Hi All,

I want to ask about IRP Design in CWMS 2.0


At our customer site, there is a policy that from DMZ(using IP public) subnet cannot access the internal network subnet.

And i am going to deploy IRP, which in the server planning guide said that both IRP real IP address and Public virtual IP must be on the same subnet.

Because of the company policy, can i use a different subnet between the Public and the Real IP address of the IRP?
