Is there an existing automated way to change the MAC address & hostname of
my home ROUTER (Linksys WRT54G)?
I know about Gorlani's MacMakeUp manual MAC address-spoofing tool but it
works on the WinXP computer - but this doesn't help anyone behind a NAT
router - as the ROUTER's MAC address is what the Internet "sees"
(http://www.gorlani.com/publicprj/macmakeup/macmakeup.asp).
Manually, I can change the MAC address of the Linksys WRT54G wireless NAT
by going to the Linksys WRT54G MAC Address tool inside the router at
http://192.168.10.10/WanMAC.htm - which works fine - and can do the same
with the router HOSTNAME (which the Internet also sees) - but these changes
are all manual.
Since the Linksys WRT54G router runs Linux, I started googling for a more
automated way to periodically change both the router's MAC address (which
is the only MAC address the Internet sees) and the router's host name. I
soon came across you guys in the process (e.g., Mad Macs changes both the
host name and MAC address of the PC NIC card
(http://www.irongeek.com/i.php?page=security/changemac&mode=print). But Mad
Macs won't do a thing to change the MAC address or HOSTNAME shown to the
Internet because the ROUTER's hostname and MAC address are what the
Internet "sees".
In digging through your archives for a script to run on the ROUTER, I see
you guys wrote automated scripts to spoof the MAC address & hostname of
Windows & Linux PCs
(http://www.irongeek.com/i.php?page=security/changemac&mode=print) ... but
being behind a NAT ......
Has anyone yet written a program to automatically change the MAC address &
HOSTNAME of the wireless router?
I also asked this question at binrev but haven't seen any response yet

The Internet does not see your MAC-address nor your hostname.
The MAC-address is transproted to the next hop (if at all) and that is
your ISP.
What is the purpose of changing MAC-address and hostname then?
Cheers,

Naaaaaaaah. It's my observation I get a new IP address from my ISP each
time I change the MAC address of my router and I want to automate that so
that a web page which "captures" my IP address and hostname doesn't get the
same one twice.
How would YOU accomplish that?

When changing your MAC address, you're effectively resetting your
connection. Upon reconnect, you're getting a new IP address assigned.
Don't you think that pulling the plug or pressing the reset button is a way
easier method for achieving this? Or, uh, what about the "Disconnect" button
in your router's config menu? D'oh!

What a nonsense. Anyway, why don't you try something like a PROXY?

Thinking first and then asking the RIGHT question. You're extremely far off
from your actual problem, and only wrong conclusions in between.
