Enable the router

Configuring the Router Functions

The router features are enabled when NAT is enabled. By default, NAT is disabled. To enable NAT:

1.In Watcher, select Tools > Options > MP.

2.Under Network Settings, select Network Address Trans‐ lation (NAT) and from the drop‐down list select Enabled. The MP modem automatically resets in order for the change to take effect.

File and resource sharing over LAN

When NAT is enabled on the MP modem, its router capabil‐ ities allow you to share files and resources such as printers, fax, etc. between computers on the LAN.

Static IP and TCP/UDP port forwarding in NAT mode

If desired, you have the option to set up static IP addresses and TCP/UDP port forwarding. The following sections describe these optional settings in more detail.

Set up static IP addresses

Static IP addresses are used to assign a predefined IP address to a specific client on the local network. The client is identified by its MAC address. When Static IP is used in conjunction with NAT port forwarding, it allows a server application to reside on the local network and receive unsolicited data/requests from a remote client on the external network.

Private IP addresses in the range 192.168.1.20 to 192.168.1.254 for Ethernet and 192.168.2.20 to 192.168.2.254 for wireless LAN are available for use as static IP addresses.

You can set up a maximum of 10 static routes, and these routes can apply to either an Ethernet or WAP interface. To set up static routing, you need to know the MAC address of the computers you want to configure.

To configure static routes:

1.Unlock the MP modem configuration. In Watcher, select Tools > AT Commands and enter the AT!MPCFGOPEN=ʺxʺ, where “x” is the password. (Default password is MP3G, e.g. AT!MPCFGOPEN=ʺMP3Gʺ)
