Hello all,
the home access point connected to the phone line have a mac address
or no ?
I think it has one MAC ,but I'm not sure.
PPPoE used in DSL modem/router
encapsulates IP packets inside
ethernet frame ?
Thanks

I assume that you're asking about the /outside/ network interface.
It depends on the specific technology in use.

There are almost always (at least) two interfaces network interfaces;
one /outside/ and one /inside/. They usually are Ethernet like and have
a MAC address.
That's traditional routers.
Wireless routers usually have an additional /inside/ interface that is
the wireless portion.
Wireless access points are in and of themselves different critters.
They typically have a wired interface and a wireless interface (bridged together), each of which have their own MAC.
Note: Wired and wireless MACs are different from each other. (Simplistically, Wireless MACs are a superset of wired MACs.)

Yes.
The "E" is the pertinent part. There is also PPP over ATM, which being
ATM does not use MAC addresses. Hence depending on the specific technology.
Thanks
You're welcome.

They have the internal/ private lan interfaces with private IP ,
and one public throught PPPoE .
I know, using a packet sniffer as wireshark or airodump it's visible
the MAC address of a AP router.
It's different from ethernet interface ( they have typically 4 ethernet
port with the same MAC).
How may I know the MAC address inside PPPoE frames? AP/routers don't indicate MAC address of the public interface.
They have same version of linux/BSD embedded, a small web server,
and a little shell like busybox accesible via telnet.
Thanks
