Do you mean capturing the ethernet packet on you ethernet adapter (that
contain pppoe)
or the packets on the dialup pseudo adapter that windows/3rd party software
creates to create the pppoe tunneling?
WinPcap (all versions) is able to capture on the former adapter (as it's a
normal ethernet adapter); winpcap 3.1 beta *should* be able to capture from
the latter adapter (ppp dialup), too.
Have a nice day
