Paul,
I don't believe you can get the remote MAC address.
The MAC address is only used on the physical cable that connects the
computer to the next router.
The MAC address is invisible beyond that.
The MAC address is used to uniquely identify each device connected to the
same subnet.
Each router has 2 mac addresses, one for each end that it is connected to.
A MAC address is like the name of the airports
you want to fly from Paris to Beijing.
You get a ticket and it say Paris Charles-De-Gaulle10am, Beijing 11pm
- and that's all.
(ie you know the IP address=Paris and IPAddress=Beijing and your
own MAC address=charledegaul airport.)
you don't know the name of the airport (MAC Address) in Beijing
But your ticket also didn't tell you you had stopovers in Moscow and
Tashkent (ie two routers)
And it didn't tell you the names of the airports (MAC addresses)
in moscow and tashkent,
(or that you had to take a bus from one airport to the other in
Moscow)
Think about it also this way.
A MAC address identifies the manufacturer and ID of the network
device.
if you could get the MAC address then you would know the manufacturer
of the network device and potentially any backdoors, and would have
powerful marketting information.
You could also found out what router your bank's online website was
connected to and that would be a security breach.

I'm confused. How does getting the source mac address help with getting
the remote one? Am I missing something here?
