We assume here that your cable/ADSL connection is down and that you need to setup a router on your old laptop equipped with a combo Ethernet/Modem PCMCIA card. What follows describe the configuration of this emergency dial-up modem router. Your external interface (to the internet) will be using the modem facility of your PCMCIA card whereas your internal interface (to your internal network) will be connected to the ethernet network plug of your PCMCIA card (eth0).

What follows has been tested with Bering v1.0-rc1 and the pmcia_xircom.lrp package on a NEC Versa SX using a Xircom RealPort EThernet 10/100 + Modem 56k - ref REM56G-100BTX.

The PCMCIA-Howto and the PPP-Howto are useful references for this section.
