del modemo tu teisus ;) paskubejau parasyt.
na o is principo... imu eth1(int) nustatau kazkoki sugalvota ip(pvz 
10.1.1.1), gateway - routerio adresas(192.168.2.250 siuo atveju). tada eth0: 
nustatau ip (192.169.10.1). tada gateway dedu 10.1.1.1?
turiu toki steb-by-step bet net ir taip nesigauna :)
