Noob question on VS and node

Hi all, I have a F5 here being setup by the previous F5 administrator.

 

Our previous webserver was 10.8.6.19 and it was replace by this F5 10.8.10.12 and 10.8.10.14 are the Application server.

 

I don't quite understand is that why is the VS is set as the web server IP and not the application server ?

 

When I check on the firewall, the public IP is pointing to 10.8.6.19 which makes me more confusing.
