4.2 Network Address Translation (NAT)
Network address translations enable sharing a single IP address for multiple computers. Without NAT, all computers must be
assigned a valid Internet IP address to connect to the Internet. Since Internet service providers only provide a few IP addresses to
every user, use NAT technology to share a single Internet IP address with multiple computers on the local network.
Follow these instructions to set NAT parameters:
