Actually, it is the ethernet card.
I know it doesn't seem to make sense, but that's the way cable ISPs
work. The modem is a sortof bridge, and the ethernet MAC address passes
through. You can verify it quite easilly if you run arpwatch on a gateway.

Supposedly its that way, only AFAIK hardware suppliers reuse mac

Tell me after you actually do it (that is - find a way to upload a
custom firmware and crack that firmware to change the MAC address).

You're right - the tunnel adds yet

Totally agree with every word. Yet my couple cents:
The reason behind enforcing PPTP/PPPoE/PPPoA/L2TP/whatever tunnels is
provisioning, accounting and QoS - all those can not be done to the
satisfying extent when you are connected directly through DHCP.

Hi Guy,
Maybe it wasn't your point, but it's all in the best traditions of
driving a high level discussion into technicalities :)
When on DHCP, the ISP has no ability to identify and classify the
client. Consider the following services that ISPs provide today:

And what about the cases when you have a mail server spreading SPAM
