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 4.59)
− 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.
