Configuration
|
|
#############
|
|
|
|
The wirelessmodem interface provides access (through a wireless modem/wwan) to
|
|
wireless networks provided by various cellular providers. VyOS uses the
|
|
interfaces wirelessmodem subsystem for configuration.
|
|
|
|
Address
|
|
-------
|
|
|
|
.. cfgcmd:: set interfaces wirelessmodem <interface> apn <apn>
|
|
|
|
Every WWAN connection requires an :abbr:`APN (Access Point Name)` which is
|
|
used by the client to dial into the ISPs network. This is a mandatory
|
|
parameter. See the following list of well-known APNs:
|
|
|
|
- AT&T (isp.cingular)
|
|
- Deutsche Telekom (internet.t-d1.de or internet.telekom)
|
|
|
|
.. cfgcmd:: set interfaces wirelessmodem <interface> backup distance <metric>
|
|
|
|
Configure metric of the default route added via the Wireless Modem interface.
|
|
The default metric if not specified is 10.
|
|
|
|
.. cfgcmd:: set interfaces wirelessmodem <interface> device <tty>
|
|
|
|
Device identifier of the underlaying physical interface. This is usually a
|
|
ttyUSB device, if not configured this defaults to ttyUSB2.
|
|
|
|
.. cfgcmd:: set interfaces wirelessmodem <interface> no-peer-dns
|
|
|
|
Do not install DNS nameservers received from ISP into system wide nameserver
|
|
list.
|
|
|
|
.. cfgcmd:: set interfaces wirelessmodem <interface> ondemand
|
|
|
|
Enables or disables on-demand WWAN connection.
|
|
|
|
Use this command to instruct the system to establish a PPP connection
|
|
automatically once traffic passes through the interface. A disabled on-demand
|
|
connection is established at boot time and remains up. If the link fails for
|
|
any reason, the link is brought back up immediately.
