====== Using parprouted ======
The core of getting this to work is [[http://freshmeat.net/projects/parprouted/|parprouted]]. The other stuff is just
scripting to make things easy.

Make the proxy arp script; I put mine in the /usr/local/sbin directory:
  #!/bin/sh
  # This script will allow wireless bridging when interface is in managed (client) mode
  #
  # Requirements:
  #    parprouted (http://freshmeat.net/projects/parprouted/)

  echo "Turning on IP Forwarding ..."
  echo 1 > /proc/sys/net/ipv4/ip_forward
  
  # Make the bridge
  parprouted eth0 ath0
  
  # Set up default gateway and routes
  route add -host <GATEWAY IP> dev wlan0
  # List all hosts the bridge is connected to
  route add -host <IP ADDRESS> dev eth0
  route add -host <IP ADDRESS> dev eth0
  # Default Gateway
  route add default gw <GATEWAY IP>

Make sure that you chmod +x it so that it can be run.

Next make sure your /etc/network/interface file is setup:

  # Used by ifup(8) and ifdown(8). See the interfaces(5) manpage or
  # /usr/share/doc/ifupdown/examples for more information.
  auto lo
  iface lo inet loopback
  
  auto eth0
  iface eth0 inet static
       address 192.168.5.5
       netmask 255.255.255.0
       broadcast 192.168.5.255
  
  auto wlan0
  iface wlan0 inet static
       address 10.0.0.9
       netmask 255.255.255.0
       broadcast 10.0.0.255
       up iwconfig wlan0 essid voyage mode Managed
       #up iwconfig wlan0 key 123456789012
       up proxy_arp.sh
  
The IP's really do not matter they can be whatever, I used a "dummy" IP
on the ethernet interface and then a "real" IP on the wireless interface
for management purposes.

That should be all there is to it. If you have questions about this
please write the list so everybody can benefit.

Hope this helps everybody who is interested,
