So that's authentication the broadband router does to your DSL
provider, e.g.:
Our ISP is using the PPPoE
...logging in over PPPoE?
and we are using the Zyxel Brand Internet Sharing
Intelligent gateway. Please suggest what to do and how to capture my
WAN
Ethernet Interface with PPPoE authentication process.
So the answer appears to be "yes".
Is the "Internet Sharing Intelligent gateway" the same device as the
"DLS Broadband Zyxel Router"? I assume so. If so, and if there's an
Ethernet connection between your gateway/router and your DSL modem,
then I would get some type of *NON-SWITCHING* hub, plug the Zyxel into
the hub, plug the DSL modem into the hub, and plug a machine running
Ethereal into the hub *AND CONFIGURE ITS NETWORK INTERFACE, IF ITS
SPEED IS CONFIGURABLE, TO RUN AT THE SAME SPEED AS THE Zyxel AND THE
DSL MODEM (so that you don't have the problem described in this FAQ:
http://www.ethereal.com/faq.html#q5.1
which also explains why you want a non-switching hub). Then run
Ethereal in promiscuous mode, so it can capture the traffic going
through the hub, even if that traffic isn't sent to or from the machine
running Ethereal.
I don't have any hub recommendations; perhaps other readers do?
