Type the Standard Port Number (range = 1-65535) and press Enter. If you 
did not choose TCP and UDP for protocol, the IAD displays the following 
message:
Updating NAT Local Server entry 1, Translated IP address 
95.4.4.4
Translated Port 100 is accessible as Standard Port 65535
If you chose TCP and UDP for protocol, the IAD prompts you to enter the 
number of consecutive ports to use.

Configure NAT Alias Entry
Each NAT alias entry allows a device on the LAN (inside of NAT) to be 
accessible from the Internet via a unique IP address. The IAD only translates 
IP addresses for alias entries—port numbers are not changed.
You can create up to seven direct public-to-private IP address mappings via 
the NAT alias table.
First, assign each public IP address using option C 
− Configure Port IP 
Address on the Router Configuration menu (Figure 4.51
− to entries 1 
through 7 on the PVC or DLCI with a 255.255.255.255 subnet mask. Next, 
make alias entries to map each local IP address to a corresponding public IP 
address.
These NAT alias entries allow IP traffic to the public IP address to pass 
directly through, port for port, to the corresponding private IP address.
To configure each NAT alias entry, follow the steps below.
1
Type “A” on the NAT Configuration menu to select Configure NAT Alias 
Entry. The IAD displays the next unassigned entry and prompts you to enter 
the NAT Alias Entry to configure.
2
Type the number of the alias entry to configure. The IAD displays the 
current local IP address and prompts you to enter a new NAT Alias Local IP 
Address.
3
Type the IP address of the device on the LAN. (It must be a statically 
assigned IP address; do not use DHCP to assign this address.) The IAD 
displays the current Internet IP Address and prompts you to enter a new one.
4
Type the new NAT alias IP address and press Enter. The IAD displays the 
information you’ve entered and updates the configuration. 
5
When the operation is complete, press any key to display the NAT 
Configuration menu.
