    hello all,

    this is my first post so go easy on me please ......

    I would like to run my WRT54G (v3.1) with dd-wrt firmware as a wireless AP as a bridge to my LAN segment. That is, I want the wireless clients to be given their IP's from my LAN DHCP server, which is *not* the wrt box.

    I currently have this setup via OpenVPN from a dedicated leg off my firewall and it works well but its just a little too involved expecially from a client point of view.

    To that end I have decided to try and implement WPA2 to make things more transparent and easier to configure.

    What I would like to know is can I setup WPA2 encryption on the wrt and *only* give out IP addresses to clients that successfully authenticate ? For all I know this may be the way that this stuff works but I haven't tried it yet. I basically only want the network to be open to authenticated clients. Can this be done with WPA2 ?

    Any advice/experience would be appreciated.

    that's the way encryption works, they have to successfully associate with the ap, before they will be assigned an IP address.

    you can disable DHCP on the router, once the user authenticates (like thibor said, its what encryption is) and the way DHCP works is a broadcast so if the router doesnt know what to do with the packets, it will forward the request to a computer that cares (the dhcp server) and that server will then issue the IP address. The Router will be encrypted and authenticating the wireless clients and then your server will distribute IP addresses. you can then block based on MAC addresses or reserve etc.
    Gots it?
