First off; thanks for a fantastic product!

I'm testing & going some device builds inside a VM. (though I'm not entirely sure the issue is VM-specific)

I run Ubuntu 64-bit (Hardy & Intrepid; work & home respectively), KVM & 2 NIC's & both the bridging control set up OK.

My LAN is 10.0.0.0/24 & my WAN is 192.168.0.0/25. No VLAN's defined

So far so good.

I do a fair whack of other work on the same boxes & consequently have to drop & recreate/remap interface of the virtual systems.
After altering interfaces (& therefore MAC's), only the LAN interface if OK, but WAN is completely down.

"Assign Interfaces" at terminal only picks up the previously assigned MAC addresses.
I need to do a "Reset to Factory Defaults" & so force the re-detection of interface before I can get WAN communicating with nodes on the WAN.

All that works in this scenario is interface-0, despite having the incorrect MAC (which at least allows me to get in & do the reset)

A possible solution may be to flush & force the re-detection of interface when selecting "Assign Interfaces" from the console menu

Thanks
