3.4.3.6.4 NAT
The
NAT Configuration
page allows the user to set the configuration for the Network Address
Translation.
Dynamic NAPT:
It provides dynamic Network Address Translation capability between LAN
and multiple WAN connections, and the LAN traffic is routed to appropriate WAN connections
based-on the destination IP addresses and Rout Table. This eliminates the need for the static
NAT session configuration between multiple LAN clients and multiple WAN connections.
NAT (Static):
This option maps single WAN IP address to the local PC IP address. It is peer-to-
peer mapping, one-to-one. For each WAN interface, only one local PC IP address can be
associated with each WAN interface. Click the link
Session Name Configuration
to add the
session name for WAN interface.
NAPT (Static):
This option maps the single WAN IP address to many local PCs IP addresses,
one-to-many. It is the multiple-mapping mechanism. For each WAN interface, more than one
local PC can be associated with one WAN interface. Click the
Session Name Configuration
to
add the session name for WAN interface.
Session Name:
Enter the desired session name.
User’s IP:
Allows the user to assign the IP address to map the corresponding NAT/NAPT
sessions.
Session Name status will be displayed at the middle of this page to show the corresponding
Session Name with its IP address.
Click
Session Name Configuration,
the following screen displays.
