need to be public IP addresses.
If NATing needs to be performed in the example above to hide individual addresses from the
Internet, it would have to be done by a device (possibly another D-Link Firewall) between the
192.168.10.0/24 network and the public Internet. In this case, internal IP addresses could be used by
the users on Ethernet network pn2.
4.7.3. Transparent Mode Scenarios
Scenario 1
The firewall in Transparent Mode is placed between an Internet access router and the internal
network. The router is used to share the Internet connection with a single public IP address. The
internal NATed network behind the firewall is in the 10.0.0.0/24 address space. Clients on the
internal network are allowed to access the Internet via the HTTP protocol.
