F5 LTM setup with Cisco FWSMs
I am going to setup F5 LTMs in our environment for server load balancing. I have a question about the placement of F5 LTMs. We want to use our existing Data Centre Gateway Switch to connect to F5. These data center switches have Firewall module in place which acts as a gateway for the servers in the data center.
Now with F5 (not acting as firewall) what is the best placement of the device, should we place F5s behind the firewall so all traffic first pass through the Firewall module and then hit the F5 external interface. The F5 internal interface will have VLANs configured for the servers connected to it. These servers will point to F5 as gateway. Is this the correct approach?
Is there any design document that can help in setting up such requirements? What is the best practice. Any help would be appreciated?
