Non-NAT mode

In non‐NAT configuration, you can connect only one client device, such as a computer to the MP modem, as shown in Figure 5‐1.

In this mode, the IP address obtained from the external network is passed directly to the client device, which is why there can be only one client.

NAT mode

In NAT mode, you can connect up to 10 devices to the MP modem using Ethernet connections and up to 10 additional devices using WAP.

In this mode, the IP addresses assigned by the MP modem to the client devices are private IP addresses. The MP NAT manages the translation of IP addresses and ports between the local and external networks.

The following illustration shows a sample network with 4 computers, two connected on an Ethernet LAN and two connected with WAP.
