I have a nework with 2 tier firewall that consist two different types. I am trying to understand how the data traffice flow for first and second tier firewall. How the internal user data flow and how out side traffic flow into the DMZ and internal side.
Based on the attached network diagram i have both WLAN and DMZ data flow at the DMZ zone . And I have user VLAN and App & DB VLAN both at Corporate Core and DC Core.
I have limited knowledge as how to translate the network diagram and figure out the data traffc flow from outisde to inside , vice versa. I am specially confuse how the 2-tier firewall function within data being transverse.
Besides, can assume the inter vlan routing will be transverse through the 2-tier Firewall ???
Appreciate your expert advise . Thanks
