Sierra Wireless MP 880W manual Problem created by Network Address Translation

Note: A similar problem may occur if NAT is in use on your network. The host application may reside on a server that has a private IP address. You must configure the MP modem to send data to a server on your network with a public IP address, and configure the server to recognize the MTP data and route it appropriately.

Sending Data to Your Network Application

The problem created by Network Address Translation

Many service providers use NAT (Network Address Trans‐ lation) which effectively creates a firewall in front of the network. Inside the network, the service providers assign private IP addresses to registered devices, since public IP addresses are not needed to route data within the network. (This saves the service provider the expense of having a large pool of public IP addresses.) A public IP address is substituted for the private IP address when data packets pass through the gateway between the network and the Internet. This public IP address might be used on data transmissions from many different devices. Therefore, the network server is only aware of the substituted public IP address. If the server replies to this address, the network cannot identify the device for which the data was intended.

Assume, for example, an MP modem is registered on a network. The MP modem is assigned a private IP address of 10.95.236.1. When the MP modem sends MTP data to the network server, a public IP address of 24.7.6.30 is substituted at the gateway to the Internet. When the network server receives the data, the host application is only aware of the public IP address, 24.7.6.30. However, if the network server sends data back to the IP address 24.7.6.30, the network has no way of identifying the MP modem for which it is intended and is unable to route the data appropriately.

Figure 7-1: An MP modem connected to a network server. In this scenario, the IP address is “NAT’d” from 10.95.236.1 to 24.7.6.30. The network server is only aware of the address 24.7.6.30, but if it sends data to that address the network cannot route the data to the MP modem.
