Network Address Translation (NAT) Default Settings
NAT default settings let you specify whether you want your Motorola Netopia® Gateway to forward NAT
trafﬁc to a default server when it doesn't know what else to do with it. The NAT default host function is
useful in situations where you cannot create a speciﬁc NAT pinhole for a trafﬁc stream because you
cannot anticipate what port number an application might use. For example, some network games
select arbitrary port numbers when a connection is being opened. By identifying your computer (or
another host on your network) as a NAT default server, you can specify that NAT trafﬁc that would other-
wise be discarded by the Motorola Netopia® Gateway should be directed to a speciﬁc hosts.
set nat-default mode [ off | default-server | ip-passthrough ]
Speciﬁes whether you want your Motorola Netopia® Gateway to forward unsolicited trafﬁc from the
WAN to a default server or an IP passthrough host when it doesn't know what else to do with it.
set nat-default dhcp-enable [ on | off ]
Allows the IP passthrough host to acquire its IP address via DHCP, if ip-passthrough is enabled.
set nat-default address ip_address
Speciﬁes the IP address of the NAT default server.
set nat-default host-hardware-address MAC_address }
Speciﬁes the hardware (MAC) address of the IP passthrough host. If the MAC address is speciﬁed as
all-zeroes, the ﬁrst DHCP client that requests an IP address gets the passthrough address.
