Network question

Hi all, as I'm a system person and trying to understand more on the network side. As below I have setup the Mgmt, internal and external IP.

 

From my understanding, Public IP will come to the firewall and on the firewall it should have a rule to reach the Virtual Server IP. From the Virtual IP, it will follow the Pool Load Balancer setting which will point to the internal Application server.

 

If there's a need to troubleshoot, will the internal and external IP play any part ? My thinking was that the internal IP is communicating to the internal application servers.

 

eth0

 

Link encap:Ethernet

 

HWaddr xx:xx:xx:xx:xx:xx inet addr:10.1.9.15

 

Bcast:10.1.9.255 Mask:255.255.255.0

 

eth1
