Your unix box will in effect have 2 network interfaces, modem and NIC.  The 
modem will have its IP address assigned by the ISP dynamically, but you must 
assign a *static* address for your NIC (e.g. 192.168.0.1).

Unless you are using Dynamic Host Configuration Protocol, you must assign a 
*static* IP address (e.g. 192.168.0.2)
