Hi, I am just trying to understand better how does the NAT work and I have problem to understand the topology below. The question which I have is: why the link between firewall and the router is using public address, rather then private ? The router to which firewall is connected has already a public address on its interface, so if we are mapping a private address to the public, in this case hosts: Main File Server and Development Server, is that necessary that the Firewall have to have a public IP address on its link to the router, even if a router behind has a public IP?

Hi @mikolajkoziel94 ,
I share my impression:
Apparently, the process of translating private addresses to public addresses does so before routing packets outside the LAN.
This is not the usual procedure, but it is possible and it may be that the search for IP from end to end is more difficult.
Moreover, if you wanted, you could translate the public addresses used in the LAN by other public addresses in the border router.
