trace if a server in a network path behind a firewall

[LearningGuy]

How do I trace if a server in a network path behind a firewall?

The data is presented in the table below.
For example: IP 192.168.1.7 of server-A is connected to "LoadBalancer-to-Server" network, LoadBalancer-A is connected to "LoadBalancer-to-Server" network and "Firewall-to-Loadbalancer" network.
So, server-A is behind a firewall.
Please suggest. Thanks

ip	name	network	behindfirewall
192.168.1.1	LoadBalancer-A	Loadbalancer-to-Server	yes
172.168.1.1	LoadBalancer-A	Firewall-to-Loadbalancer	yes
192.168.1.7	server-A	Loadbalancer-to-Server	yes
192.168.1.8	server-B	Loadbalancer-to-Server	yes
192.168.1.9	server-C	network-1	no
192.168.1.9	server-D	network-2	no

This requires some discovery work from your organisation or network engineer, Splunk can't magically work out a network's connections unless you have data that states so. 

An option might be to ingest the data from these components and ensure the source_ip and destination_ip data is ingested and that may help you see the traffic flow  and you can use a Splunk app with the discovery work.  like https://splunkbase.splunk.com/app/6876   

Or you might want to look at, other third-party tools for that and perhaps then create a look up file that contains this information, so its then presented to Splunk and to help you with your use case.
