Configuring Network Address Translation
This chapter provides Network Address Translation (NAT) instructions for modifying the
default configuration on your device.
Your Default NAT Setup
By default, NAT is enabled, with a napt rule configured to perform the following translation:
{
XE
"NAT:default configuration"
}
These private IP addresses:
...are translated to:
192.168.1.2
192.168.1.3
.
.
.
192.168.1.13
Your ISP-assigned
public IP address
For a description of napt rules, see page 33. This default NAT setup assumes that, on each
LAN computer, you configured TCP/IP properties as follows:
?
You selected the check box that enables them to receive their IP addresses
automatically (that is, to use a DHCP server);
or,
?
You assigned static IP addresses to your PCs in the range 192.168.1.2 through
192.168.1.13.
If your computers are not configured in one of these ways
, you can either change the IP
addresses on your computers to match the NAT setup or delete this NAT rule and add a new
one that matches the addresses you assigned to your computers (see “Adding NAT Rules” on
page 33 for instructions).
Viewing NAT Global Settings and Statistics
{
XE "NAT:global settings"
}
To view your NAT settings, log into Configuration Manager, click the
Services tab. The NAT Configuration page displays by default, as shown in Figure .
