[Soekris] Wifi Bridging with Metrix Pyramid

[Scott Houppermans]

While not the best forum for this post, due to the lack of online
information on Pyramid, I'm throwing this out there to see if anyone else
has built a Wifi AP with Metrix Pyramid on a Soekris box.  I've been
following the article
(http://pyramid.metrix.net/trac/wiki/ArticlesAndHowtos) on how to build a
wifi ap, but have run into a few snags.
I'm running pyramid 1.0b1 that I have pxe booted to a Soekris 4526.  Wifi is
provided by a Compex WLM54G High Power 802.11b/g mini PCI Card (Atheros
AR2413 chipset) from Netgate.  NTP servers have been set and DHCP relay is
set to forward to my blue interface on IPCop for centralized DHCP service
and lease monitoring.  The trouble comes after I edit the
etc/network/interfaces file to create the bridge between ath0 and eth0.
Here's what I get;

        Here is my etc/network/interfaces file;

#/etc/network/interfaces
#simple bridge between
#eth0 and ath0

auto lo
iface lo inet loopback

#auto ath0
iface ath0 inet static
        address 10.10.7.1
        netmask 255.255.255.0
        broadcast 10.10.7.255
        gateway 10.10.6.1
        post-down wlanconfig ath0 destroy
        pre-up wlanconfig ath0 create wlandev wifi0 wlanmode ap # Set by

rts off frag off # Set by WiFiAdmin
        pre-up ifconfig ath0 up # Set by WiFiAdmin
        pre-up sleep 3 # Set by WiFiAdmin

#auto eth0

        gateway 10.10.6.1

auto br0
iface br0 inet static
       address 10.10.6.5
       netmask 255.255.255.0
       broadcast 10.10.6.255
       gateway 10.10.6.1
       bridge_ports ath0 eth0
       post-down wlanconfig ath0 destroy
       pre-up wlanconfig ath0 create wlandev wifi0 wlanmode ap
       pre-up iwconfig ath0 essid "testwifi" channel 06 rate auto rts off
frag off
       pre-up ifconfig ath0 up
       pre-up sleep 3

        When I uncomment ath0 and eth0 and comment out br0, I am able to
connect to the LAN side of pyramid,

get to the gui and pull a wifi address (with ath0 dhcp server giving an
address for testing).  Googling the SIOCSIFADDR, SIOCSIFNETMASK, and
SIOCSIFBRDADDR errors hasn't turned up any useful information.  Any
information/help or a pointer in the right direction would be greatly
appreciated.

Blue skies,
