net.eth.nat
(Setup -> Network Settings -> Ethernet Settings -> Ethernet
n
Settings)
This setting controls whether the unit does Network Address Translation (NAT) on routed frames egressing the
unit on the specified interface. That is, when PPP routing is operating and forwarding frames received on the PPP
interface (which can be the same thing as the wireless modem interface), the unit rewrites the source IP address
of forwarded frames leaving the unit to the IP address of the ethernet interface on which they leave. If this setting
is disabled then forwarding may still happen since it is governed only by the PPP routing settings, but the source
IP address of the forwarded frames is not rewritten.
net.wireless.defaultrouteenable
(Setup -> Modem Settings -> Wireless Modem Settings)
When ON, the wireless interface is set as the default route when connected (which is either never, or all the time,
with our current options). When OFF, the wireless interface will not become the default route when connected.
The default is OFF. For a change to this setting to take effect and if the wireless link is already up, the wireless
link must be restarted. . While it is possible to detect a change to this setting and automatically restart the wireless
link, an ongoing session will get interrupted. To avoid this, restart the wireless connection, using the
WIRELESS
RESTART
command. This brings down the wireless link, and it automatically comes back up with the new setting
in effect.

Operation
With
net.wireless.mode
set to PERMANENT (depending on the type of modem installed), the unit attempts to
maintain a connection to the wireless network at all times. If the connection goes down for any reason, including
inactivity, the unit immediately attempts to reconnect. When there is no activity on the link for longer than the
inactivity timeout (see below), the connection is terminated and immediately restarted. If
net.wireless.mode
is
set to OFF, wireless modem operations are terminated immediately (there may be up to a minute's delay if certain
operations are pending).
The
WIRELESS RESTART
command causes the wireless modem to terminate the connection and restart it
based on the current settings; this is useful if a setting other than "mode" is changed.
The default setting for the wireless connection is to NOT be the default route for outbound IP frames. A static
route must be entered for any frame to be sent out on the wireless connection. If Default Route Enable is changed
to ON for the wireless connection, then all IP frames that do not match an existing static route will be sent out on
the wireless connection. For situations where the wireless modem is the only means of off-net access, Default
Route Enable
should be set to ON.
The front-panel MODEM LED shows the status of the wireless modem. If
net.wireless.mode
is set to OFF
then the LED should remain unlit. When
net.wireless.mode
is set to PERMANENT the LED flashes once per
second while the modem is attempting to establish a network connection. Once the connection is established, the
LED blinks every 3 seconds.
