[Bridge] Wired iface + Wireless iface configuration in managed mode

There are several NetGear APs that function this way, the WG302 comes to mind but it's a bit expensive.. Very nice piece of hardware though... I have a question though, why do you want to use an AP? Why not just set up another linux bridge with a wireless card and have that act as an AP? You can buy Prism2.5/3 based cards for like $20-30 now... -Chris

[Bridge] Wired iface + Wireless iface configuration in managed mode
Hi all, I have to set up a bridge in the following configuration: 1 Wired Interface 1 Wireless Interface in Managed Mode (ie connected to an access point) The architecture is as follows: Private Internet ------- Wireless Router/AP ---- air ----- Linux Bridge ----wire----- Host A So let's say I have a host (Host A) connected to the wired interface of that bridge, I would like to be able to communicate with hosts that are behind the wireless router (ie the private Internet) The problem is that when the Linux bridge forwards Host A's Ethernet frames to the AP, the AP doesn't allow these frames to pass through, because Host A isn't a regular wireless client who has been authenticated/associated (802.11).
