CSS to F5 migration

HI Kai Wilke Thanks for the response. on the query B about the Public Subnets running out of Public IP issue, do you think i could NAT for the Public IP's to a Private IP in the firewall and then setup LTM Virtual SErver with those private IP. The issue with the setup is that the F5 will be connected to a L2 switch which also has all the servers connected to it.So, in cases of Public IP directly assigned to servers i will need to create a VLAN in F5 in order for those servers to use it as default gateway and without 3 available Public IP's i'm stuck in this step.. Any way out ?
