hi there,
you are using server mode onto your openvpn server side,
that means that server assings ip automatically to your clients,
so remove this from your client
>ifconfig 192.168.255.2 192.168.255.1
the first ip that your client vpn interface will be 192.168.255.6.
also i guess that you are testing the config with both server/client in the same lan?
if yes ,pushing routes is bad idea...
test your setup via internet..
also having 2 different nics (lan&wlan) belong to same range is not a good idea...
also you must enable routing on openvpn server to routing to work..
Michael.
