This chapter describes the steps required to configure Network Address
Translation (NAT).
NAT multiplexes traffic from the internal network and presents it to the
Internet as if it is from a single source that has only one IP address.
The NAT Local Server may be configured with a range of both TCP and
UDP ports, which benefits applications including video conferencing and
multi-user games.
Setting up IP networks without NAT may be complex—each requires an IP
address, subnet mask, a DNS address and a default router.
NAT reduces this complexity by:
Modifying IP addresses and checksum without affecting traffic
Automatic network configuration when using DHCP
Packet-level filtering and routing
Traffic logging
