Network Address Translation (NAT) Default Settings
NAT default settings let you specify whether you want your Netopia Gateway to for ward NAT
traffic to a default ser ver 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 por t number an application might use. For
example, some network games select arbitrar y por t numbers when a connection is being
opened. By identifying your computer (or another host on your network) as a NAT default
ser ver, you can specify that NAT traffic that would other wise be discarded by the Netopia
Gateway should be directed to a specific hosts.
set nat-default mode [ off | default-server | ip-passthrough ]
Specifies whether you want your Netopia Gateway to for ward unsolicited traffic from the
WAN to a default ser ver or an IP passthrough host when it doesn’t know what else to do
with it. See
for more information.
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
