Enabling/Disabling Hide NAT

Network Address Translation (NAT) enables you to share a single IP address among several
computers.
Note
NAT can only be disabled in IP40 Satellite X licenses. NAT is enabled by default. If NAT is
disabled, you need to buy an IP address range.
To enable NAT
1. In the Navigation Bar, click Network > My Network.
The My Network page appears.
2. Select Enabled.
3. Click Apply.
NAT is enabled.

Configuring a DMZ Network

In addition to the LAN network, IP40 allows you to define a second internal network called a
DMZ (Demilitarized Zone) network. By default, all traffic is allowed from the LAN network to
the DMZ network, and no traffic is allowed from the DMZ network to the LAN network. You
can customize this behaviour by creating Firewall user rules.
For example, you could assign your company's accounting department to the LAN network and
the rest of the company to the DMZ network. The accounting department would be able to
connect to all company computers, while the rest of the employees would not be able to access
any sensitive information on the accounting department computers. You could then create
firewall rules that allow specific DMZ computers (such as a manager's computer) to connect to
the LAN network and the accounting department.
Nokia IP40 User Guide
If you changed the internal network range to X.X.X.X, the IP address of the IP40 is
changed to X.X.X.1
If you chose to reset the network to its default settings, the settings are reset.
If your computer is configured to obtain its IP address automatically (using DHCP), and
the DHCP server in your IP40 is enabled, restart your computer. Your computer obtains
an IP address in the new range.
Otherwise, manually reconfigure your computer to use the new address range using the
TCP/IP settings.
