Hi,
I read a lot on the Internet, but didn't find quite what I need.
I'm not even sure it's possible.
I have a machine with ethernet access and wireless card (in master mode).
Both are running ok under ubuntu maverick.
I also have a separate firewall (wired) acting as DHCP server for my
whole home network.
I would like to bind the two interfaces together with no translation (no
NAT, SNAT, masquerading, ...) so that the machines connecting to the
wireless lan can get their address from the firewall and access the
Internet.
Is this possible with bridging?
If so: can someone point me to the right documentation?
TiA
Mauro

Have you looked at hostapd (http://hostap.epitest.fi/hostapd/)?

Sorry,
I was not clear enough.
I have the wireless card up-and-running in ap-mode using hostapd.
I *can* connect a laptop to the wireless Access Point.
I also know how to setup a masquerading router on the linux machine to
share the landline connection (e.g.: using firestarter).
This would create a second net for wireless with double natting.
I would like to avoid this and I'm looking for a "bridge" configuration
so that all machines (wireless & wired) can share the same subnet
(192.68.1.0/24).
I tried something like:
=====================
auto lo
iface lo inet loopback
auto wlan2
iface wlan2 inet manual
up /usr/sbin/service hostapd start
up /sbin/ifconfig wlan2 up
down /sbin/ifconfig wlan2 down
down /usr/sbin/service hostapd stop
auto eth2
iface eth2 inet manual
up /sbin/ifconfig eth2 up
down /sbin/ifconfig eth2 down
auto br0
iface br0 inet dhcp
bridge_ports eth2 wlan2
bridge_maxwait 0
=====================
... but it does not seem to work as hoped.
Thanks in Advance for *ANY* hint ;)
Regards
Mauro

Consider reading http://www.linuxfoundation.org/collaborate/workgroups/networking/bridge, in
particular the following sections :
- 7.11 What can be bridged?
- 7.16 It doesn't work with my Wireless card!
- 7.17 I still don't understand!!
Nicolas.

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
Mauro

hostapd puts the interface into the bridge when it starts up- but you have
to put it in the config. in your hostpad.conf add 'bridge=br0' (making sure
of course you have the correct 'interface= ' set.) search for 'bridge' on
this page: http://wireless.kernel.org/en/users/Documentation/hostapd
once setup, hostapd should put the interface in the bridge at start up and
remove it at shutdown so you take the interface out of the interfaces file.
