i have the following configuration

internet router 1.1.1.1

firewall 1.1.1.2

plus the following additional public addresses are available and used as NAT addresses

1.1.1.3, 1.1.1.4, 1.1.1.5

I just have one query.

When clients come inbound through the router attempting to connect to 1.1.1.3 (for example), how does the firewall on 1.1.1.2 know that it is to respond to these requests? I can see know ARP entries or interfaces relevant to 1.1.1.3?

Mike, once you configure a static nat using public ip 1.1.1.3 in the firewall along with access list allowing inbound traffic, firewal will respong to 1.1.1.3 and conduct proper nat translation to get to the actual system 1.1.1.3 is NATed to.
