I don't think this is correct. The firewall usually ensures private network packets do not reach the WAN interface. That is, the packets are not passed from the LAN interface to the WAN interface. Look for firewall rules for the LAN that says something like "Block private networks" (RFC 1918 networks) and "Block bogon networks" (IANA Reserved). On the other hand, NAT allows multiple hosts on a private network to use a single, public IP address when accessing the internet. Jeff
