Also noted that searching the cfe I backup via the GUI yields none of the mac address' within. However there is a generic mac addressed to el0


There is no unique mac address in the CFE, I have compared CFE's from different users and they are all same.
There are only 2 different CFE's the old 600v1.0 and the newer 600v1.1, a 600v1.0 can have a 1.1 CFE if it was refurbished by Linksys.

There are strong indications that they upgraded their current stock of unsold 1.0's to 1.1's when the 1.1 was introduced.
The FCC site shows a regulatory change of 1.0 at the same time as the 1.1 was approved and the regulatory change was an update to full 5GHz frequency band coverage.
so where are the mac's stored? How would I go about changing them? The reason i ask is i am pretty sure that the lan mac and wl1 mac are not supposed to be the same,

The MAC's are stored in nvram.

And where does it get them from to store them in the nvram?

Well, there are a few possibilities but you could start with erasing your nvram, committing the write, and then reboot to see if they appear again.

a hrad reset would accomplish the same thing and they come back the same.

Maybe, I don't know if a hard reset will erase nvram on a 600 but if you're sure it does then the mac is stored elsewhere.
What happens if you enable jffs2 (all remaining space as jffs) , enable clean jffs, reboot and then try to erase the nvram?
Do you still get the MAC's back?

No, I can't see the reset button erasing nvram when I look at the CFE code.
Makes sense to remove that function to protect router unique parameters in nvram from being erased by a user.

I was told not enable jffs or it would erase the last partition and brick the router. Not sure about the details, barryware told me.

A hard reset "can" erase the nvram, but that does not clear the mac address.

Also, enabling jffs *does NOT* brick the router. I have enabled it before, and I still have a working router.

I looked for the thread but I can not find it.. I think the part I need was split from the main thread.

There is an additional partition called "factory" on the 600. This is where the device specific data is. I was told that enabling jffs would wipe this out. I didn't try it myself.

How are your macs arranged?

I know the way it supposed to setup, but I am trying to figure out why my macs are this way:

Setup1
LAN = WAN -1
WAN = Sticker
WL0 = WAN +1
WL1 = WAN -1

I think that WL1 should be a different mac.

Setup2 (What I think it should be)
LAN = WAN -1
WAN = Sticker
WL0 = WAN +1
WL1 = WAN +2

Not sure why the WAN is the sticker. The macs are the same as setup1 with the stock linksys FW too.

As far as hard resets, I have done them before and after flashing.

Found it...

Next to the last post in the thread.. I'm not going to try it to either confirm or deny LOM's findings.

@ all 600N users.
Don't enable jffs in your routers, the board data partition in flash which contains your MAC address and all radio parameters will be overwritten!!

This will be corrected in future svn versions.

I don't want to chance it ether, but...

The next question is How do you modify that information in that partition?

I just realized my 600's mac's are further off than I thought.

LAN = 00:00:00:00:6F:EB
WAN = 00:00:00:00:8F:7C
wl0 = 00:00:00:00:8F:7D
wl1 = 00:00:00:00:6F:EB
