I would like to share my internet connection through a Wifidog hotspot -- outside clients need completely unencrypted wireless connections.  My home network already uses WPA encryption and I want my home to remain secure.  Of course, I can't string a wire through my whole apartment, so I need to WDS connect a couple WRT54GL boxes.

My question is whether/how I can configure WDS between OpenWRT boxes whose AP clients require different encryption.  Note that I wouldn't really care whether the WDS connection is encrypted.  I think this ascii diagram will clarify what I am thinking:

                 SECURE              UNSECURE
                 ======              ========
                 Home                Wifidog
                 Wireless            Wireless
                   .                   .
                   .(WPA SPK)           .(Open)
                   .                   .
INTERNET ------- OPENWRT_1 . . . . . OPENWRT_2
                   |         (WDS)
                   |
                   |
                 Home
                 Wired

Ultimately, I'll want to isolate all wifidog client traffic from my home network (i.e., allow to internet only), but I will need to administer the wifidog OpenWRT from a computer on the secured home network.
