[Winpcap-users] Using Ethernet Connection Instead of Dial-Up

[ceo at triplebit.com]

Thanks GV for the rapid answer,
Do you know any api(WInPcap or win32 or another) that I can use to retreave 
the ethernet card info(like mac address or name)  that is being used by DSL 
from the IP address of the pppoe connection?
Regards
I. Lesher
