[Voyage-linux] Building Bridges-scripts

[Andrew Niemantsverdriet]

Here is what I came up with. Should be the "debian way" or the the way
that seems to work great with voyage and wrap.

auto br0 
iface br0 inet static
   address 192.168.254.253
   netmask 255.255.255.0
   network 192.168.254.0
   broadcast 192.168.254.255
   gateway 192.168.254.1
   bridge_ports eth0 wlan0
   pre-up ifconfig eth0 0.0.0.0 up
   pre-up ifconfig wlan0 0.0.0.0 up
   pre-up iwconfig wlan0 essid testing mode master
   pre-up brctl addbr br0
   pre-up brctl addif br0 eth0
   pre-up brctl addif br0 wlan0
   post-down ifconfig eth0 0.0.0.0 down
   post-down ifconfig wlan0 0.0.0.0 down
   post-down brctl delif br0 eth0
   post-down brctl delif br0 wlan0
   post-down brctl delbr br0

Also did a little write up on the wiki under the "how do i" section:

Thanks for the help everybody:
