NAT Configuration
This section 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.

Setting up IP networks without NAT may be complex—each requires an IP

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
