Joachim,

So, you want your routers to transmit frames to an upstream firewall with
different source MAC addresses.  This is certainly possible, although it
may not work with your current network configuration--you'll have to do
some reading to know.

You'll want to look at the bridging code and ebtables:

  http://users.pandora.be/bart.de.schuymer/ebtables/

ebtables allows the transformation and filtering of ethernet frames in a
manner similar to iptables for IP packets.

-Martin

 : I use Linux boxes as routers and wonders if it's possible to have them
 : to "copy" the MAC address, so my firewall can toggle on MAC addresses.
 : Now it only see the routers MAC address, so everyone behind can go
 : through my firewall.
