9. NAT configuration
This chapter walks you through the steps required to
configure the Network Address Translation (NAT).  For more
information on the menus, submenus and commands in this
chapter, see the “Menu interface” chapter.
The setup of IP networks can be difficult and time consuming,
as each requires an IP address, subnet mask, DNS address
and a default router.
If you enter once piece of information incorrectly, the network
connection does not function and there may be no indication
of what is wrong.
NAT prevents this scenario by:
Modifying IP addresses and checksum without
impacting traffic.
Automatic network configuration - if you configure
DHCP.  For more information, see the “DHCP
configuration” chapter.
Packet level filtering and routing.
Traffic logging.
A significant advantage of NAT lies in the fact that you can
configure it without having to change host or routers – other
than those few routers on which NAT is configured.
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.
You must complete the following steps to configure NAT:
Enable NAT translation by port (factory default =
disabled)
Configure the NAT local server entry
Configure the NAT Transmission Control Protocol
(TCP) or User Datagram Protocol (UDP) timeouts
Configure the NAT port range

Configuring
the NAT
timeouts
Under normal circumstances, the timeout default setting is
adequate.  However, if you interact with multiple-player IP
games or video conferencing, you need to configure the
timeout.
The local server protocol that you select determines which
timeout to configure.  TDP and UDP are similar, except that
TCP tracks TCP clients on a per-connection basis and
removes them from the table as soon as the connection
closes.

Configuring
the NAT port
range
Under normal circumstances, the port range default setting is
adequate.  However, if you interact with multiple-player IP
games or video conferencing, you need to configure the port
range setting.
To multiplex several connections to a single destination, the
PARTNER ACS 1600 DSL module assigns all packets unique
port numbers.  Each IP packet starts with a header that
contain the source and destination addresses, as well as two
port numbers.  The addresses specify the two routers at each
end, while the two port numbers ensure the unique
identification of each router pair.
When the PARTNER ACS 1600 DSL module sends TCP or
UDP connection from a local port to an Internet port, it
changes the sent IP address to the address of the Internet
port.  Similarly, it changes the TCP or UDP connection port
number to a unique value within the NAT port range.
The NAT port range must not include any ports that use
applications such as HTTP, TFTP and so on.
To configure the NAT port range:
1. On the Main Menu, select Configure NAT.
The NAT Configuration Menu displays.

10. DHCP server configuration
This chapter walks you through the steps required to
configure the Dynamic Host Configuration Protocol (DHCP)
server.  For more information on the menus, submenus and
commands in this chapter, see the “Menu interface” chapter.
DHCP allows for dynamic allocation of network addresses and
configurations to newly attached hosts.  DHCP reduces the
work required to administer a large network.
You must complete the following steps to configure the DHCP
server:
Enable DHCP (factory default = disabled)
Configure the DHCP server parameters
Configure the DHCP address range pool
Enabling
DHCP
To enable DHCP:
1. On the Main Menu, select Configure DHCP Server.
