UMTS_FILTER Default setting: UMTS_FILTER=’yes’

ﬂi4l automatically hangs up if no traﬃc is going over the ppp0 interface in the hangup

timeout time. Unfortunately also data transfers from outside count as relevant traﬃc i.e.

P2P-clients like eDonkey. Since you will be nearly permanently contacted from outside

nowadays it may happen that ﬂi4l never hangs up an UMTS connection.

Option UMTS_FILTER is helping here. If set to ’yes’ only traﬃc generated by your own

machine is monitored and external traﬃc will be ignored completely. Since incoming

traﬃc normally leads to a reaction from the router or the machines behind it (i.e. denying

or dropping the packets) some additional outgoing packets will be ignored too.

UMTS_ADAPTER (optional)

Specify here if the hardware is a PCMCIA card, an USB adapter or a phone connected

via an USB cable.

If omitting this variable only the ﬁles necessary for an USB adapter will be copied.

Possible values: (pcmcia,usbstick,usbphone)

All variables that follow are optional and only needed if the automatic detec-

tion fails.

UMTS_IDVENDOR (optional) UMTS_IDVENDOR=’xxxx’

Vendor ID after plugging/starting the adapter

UMTS_IDDEVICE (optional) UMTS_IDDEVICE=’xxxx’

Product ID after plugging/starting the adapter

Specifying the following two parameters is only needed if the ID changes after

initialisation

UMTS_IDVENDOR2 (optional) UMTS_IDVENDOR2=’xxxx’

Vendor ID after initialisation of the adapter

UMTS_IDDEVICE2 (optional) UMTS_IDDEVICE2=’xxxx’

Product ID after initialisation of the adapter

UMTS_DRV (optional) UMTS_DRV=’xxxx’

Driver for the adapter, if omitted ’usbserial’ is used

UMTS_SWITCH (optional) UMTS_SWITCH=’-v 0x0af0 -p 0x6971 -M 555...000 -s 10’

Parameters for usb-modeswitch initialisation of the modem (see Website usb-
