Ok, you are right. (Now) I'm very confused...........

My configuration:

Internet
   |     
 Router  (managed by my ISP)
   |
   |     (wired)
   |
 My AP1  (Prism2 in PLX / hostap in master mode
   |              Bridge between eth0/wlan0/wlan0wds0)
   |     (wds)
   |
 My AP2  (Prism2 in PLX / hostap in master mode
   |              Bridge between eth0/wlan0/wlan0wds0)
   |
   |-- wired clients
   |
wireless clients

The ISP Router and AP1 are placed at the attic, accessible for everybody, so
I bought a small cabinet to secure them. That's the reason why I bought the
Nortel Card, because of its external antenna.

And now I want to associate the AP1 as a normal client to the AP2 (because
there is no master mode driver for the Nortel card), but bridge the ISP
router and the wlan anyway together. 

The ISP Router masquerades all connections, because the internal net is
192.168.0.0 and I can't add static routes so I would have to masquerade on
AP1, too. That may work, but hmm, I think there must be a better way. 

Any idea?? Maybe something like proxy arp? Remember, I don't want to connect
a whole network behind AP1, only one client(the ISP router).

And there is really no chance to get the bridge up with a wlan Card in
managed mode?

Btw, is there any difference between "managed mode" and "station mode", or
does both mean the same?

You are very confused. 

What do you want to achieve by putting a managed wireless card in a bridge?
I 
guess you want to do level 2 bridging. To do it you should have the original

source MAC (SA) and the final destination MAC (DA), which is _impossible_ in

a "managed" card, which only deal with "receiving address" (RA) and 
"transmitter address" (TA).

To make it work you need:

a) An AP that is able to bridge between its associated stations and the 
ethernet. The master interface knows the MAC of every associated station and

the ethernet has the original source and destination MAC, so bridging
between 
the ethernet and (only) associated stations is possible.

b) Or, if you want to connect two different LANs, the card/SO needs two
extra 
headers (SA and RA), and that the goal of WDS and the four headers (RA, TA, 
SA and DA).

So, put your "bridging" wireless card in master mode and add it to a
bridging 
group. Or for managed one you can only do IP routing.
