4.5.4.2. NAT
Network address translation (NAT) allows multiple hosts in a LAN to connect
to the Internet by using one or multiple public IP addresses. This feature maps
a few public IP addresses to many private IP addresses to conserve public IP
addresses. You can view and configure NAT rules on the
NAT
page. The
configuration procedure is as follows:
1. Choose
Network > Firewall > NAT
to display the
NAT
page.
2. Select an interface from the
Interface
drop-down list.
3. Click the Add icon under
Network Address Translation (NAT) Rules
to
add an NAT rule and set parameters for the rule. For details about these
parameters, see NAT rule parameter description .
4. Click
OK
to save the configuration, and then click
Submit
to apply the
configuration.
As shown in the following figure, the NAT rule allows hosts connected to the
IG502 to connect to the Internet by using the IP address of interface WAN.
