Mobile IP Settings
By default the Mobile IP settings are automatically configured by the cellular carrier
following provisioning. In cases where Mobile IP settings must be modified, the Mobile IP
page is available.
NOTE:
The mobile IP settings page is only accessible when the modem is offline. Prior to
configuration, ensure auto-connect (labeled Connect) is disabled from the Dial Settings
page.
Mobile IP
:
Disabled
– Permits Simple IP only. Using this setting may require PPP
authentication parameters to be configured on the Dial Settings page.
Preferred
– During the initial registration, mobile IP will be selected if supported by the
network. If mobile IP is not available, the modem will revert to Simple IP.
Required
– Allows only a mobile IP connection. If the modem hands off to a network that
does not support mobile IP, the connection will be dropped and stay offline until a mobile IP
network becomes available.
Reverse Tunneling
:
Enabled
- the mobile node tunnels all transmissions back to the home
agent for transmission back to the internet rather than sending datagrams directly.
Disabled –
When the mobile node is on a foreign network, transmissions to the internet will
be done directly rather than via a tunnel to the home agent.

password, check the

checkbox.
