Thanks for the pointer.
I assume the short answer (gleamed from the above link) is: "this can't 
be done (easily)".

I have it working now without bridges using hostapd, dnsmasq and a 
static route in the upstream router (ipfire).

This has the (small) drawback I have a second subnet and a largely 
useless dnsmaq installed.

My setup is with a separate firewall (ipfire) connected to the Internet; 
on the GREEN LAN I have another server with an "Atheros Communications 
Inc. AR928X Wireless Network Adapter (PCI-Express) (rev 01)" managed via 
ath9k and hostapd.
On "server" (ubuntu-workstation 10.10; I had some problems convincing 
NetworkManager not to meddle with the interfaces) I have:
========================
auto wlan2
iface wlan2 inet static
     address 192.168.2.1
     netmask 255.255.255.0
     broadcast 192.168.2.255

auto eth2
iface eth2 inet dhcp # gets address from ipfire in the range 
192.168.1.100-129
========================
IPV4 routing is enabled.
hostapd and dnsmasq are set and configured.

On "ipfire" I have the additional static route
========================
route add -net 192.168.2.0/24 gw server
========================



Any comment?
Can I simplify?
Is this The Right Way to go?

Thanks
