Figure 35 Tutorial Example: Using NAT with Static Public IP Addresses
To set up this network, we are going to:
1 Configure the WAN 1 connection to use the first public IP address (1.2.3.4).
2 Configure NAT address mapping for other public IP addresses (1.2.3.5 and 1.2.3.6).
3 Configure NAT port forwarding to forward FTP traffic from WAN 1 to a specific
computer on your local network.
