Problem COnnecting AP from Mobile Node

Your problem is probably your bridge. When you bridge two interfaces,
standard practice is as follows:
Your ethernet and wireless interface are bridged as br0 and the ip info is
then set on the bridge interface.
In your case it would be something like: (if your 192 address is a class c
subnet)
/sbin/brctl addbr br0
/sbin/brctl addif br0 eth0
/sbin/brctl addif br0 wlan0
/sbin/ifconfig eth0 0.0.0.0
/sbin/ifconfig wlan0 0.0.0.0
/sbin/ifconfig br0 192.168.2.3 broadcast 192.168.2.255 netmask 255.255.255.0
up
/sbin/route add default gw 192.168.2.1
Another problem I see is you have your roaming client's ip on a different
subnet than the access point (linux box). Your client doesn't know anything
about the other subnets. Are you using NAT to get to the internet or is this
just a private network? One easy thing to do is change the ip of the client
to 192.168.2.5 and see if you can see the rest of your network. (Try to ping
192.168.2.2 and then try 192.168.2.1)
