CentOS - Apr 2008 - New firewall, need mac changed

I have read a few ways to do this, but not 100% sure.
I need the interfaces reliably associated to the hardware (there are more than
one), so the ifcfg-ethn has the mac address in it. I need to match the mac
address of an old router that is about to be removed so I need not change any
dns related config.

Thanks!

Modify /etc/sysconfig/network-scripts/ifcfg-ethX and remove the HWADDR
line if you have one, and add a MACADDR with the mac address you want
to use.

Beware, some network cards may protest having the mac address changed,
and using both HWADDR and MACADDR can cause issues. See
/usr/share/doc/initscripts-*/sysconfig.txt for details.
