Configuring NAT
Network Address Translation (NAT) is an Internet standard that enables a local-area
network (LAN) to use one set of IP addresses for internal traffic and a second set of
addresses for external traffic. A NAT box located where the LAN meets the Internet
makes all necessary IP address translations. This chapter contains the information of
configuring NAT on the MSR2000.
The service NAT runs only in the mesh gateway. You can use the following commands
to configure the NAT service:
