Adding external IP addresses
Static NAT converts a Firebox public IP and port into specific destinations
on the Trusted or Optional networks. If you want to use an address other
than that of the External interface itself, you must designate a new public
IP address using the Add External IP dialog box. From Policy Manager:
1 Select Network => Configuration. Click the Aliases button.
The Add External IP dialog box appears.
2 At the bottom of the dialog box, enter the public IP address. Click
Add.
3 Repeat until all external public IP addresses are added. Click OK.
