multiple subnets within a vlan not allowed?

We tried this on 9.4.8 and it seems to be working fine, virtual servers configured on all four subnets, just told by the F5 tech can't do that. Do you know what problem you had?

 

I wonder how to make these four subnets which are on the same vlan on cisco available on the F5? So we need to create four different vlans using untagged interfaces one for each subnet?

 

 

Thanks!!
