Hi All,
We're attempting to replace all the Engenius CB3s and various
Airports and AP3s in our backbone with WRAP boards running pebble
linux with 200 mW senao cards.
We've got the host AP config bridging to the ethernet interface
just fine. What we have not been able to get running is a WRAP
board functioning as a wireless bridge with the radio as a client
of an upstream AP -- that is hostap in managed mode.
I found this thread on the hostap discussion board, but it seems to
lead to a dead end.

The statement "But still, a WLAN card in "Managed" mode can't be
bridged." doesn't ring completely true to me, since the WEP11 from
linksys and the CB3 from senao/engenius do this with prism based
radio cards.
I've found other online discussions that mention layer 2 bridging,
but that's what we have running with hostap, but it doesn't work
when the wireless interface is a client of another AP.
Because hostap doesn't have virtual APs, though Jouni certainly knows
how to do the work (Devicescape supports same).
Is there a set of drivers other than hostap that we should be using
or do we need to do somethings with ebtables to set up MAC-NAT?
What you really want is a client mode driver that, if presented with
a packet for a (layer 2) address other than its AP, will encapsulate
as a 4-address frame and send it to the AP.
That way you get "transparent layer 2 bridging", without any of the
bullshit layer-2 NAT stuff that people tend to develop. Nice,
standards-based approach. If you're careful, all that normal WPA
stuff "just works" too.
I took '[EMAIL PROTECTED], & 'pebble-linux' off the distribution
list, (I don't subscribe to either) but feel free to echo my comments
back to them.
