F5 LTM - load-balance multiple network segment with cross-talk
I am planning to deploy the new BigIP LTM to the current 2 server firms. We have Web-Farm(192.168.1.0/24) and App-Farm(192.168.2.0/24) separated by Firewall for security.
We don't want to change the IP addressing thus opt for VLAN-Group to make LTM as inline deployment.
We only have budget for 1 pair of LTM thus I need to use the same LTM for both Web & App Firm. Means, LTM will have 2 connections to Web segment and 2 connections to App segment.
Normally, traffic will flow from Internet -> Web and Web -> App.
Now my question is :
After LTM is deployed, when Web Server(Real) talk to App Server(Virtual), how the traffic will flow? Is web server traffic hit to firewall or is it going to be routed by LTM?
My objective is to force the traffic to pass through via Firewall for security reason.
Thanks in advance for help and hope to get this work.
