disabling NAT specific settings

    I have the following setup:

    DSL modem ----> linux shorewall server ---> switch ----> wired clients (192.168.1.*)
    ---> linksys wrtp54g (
    ---> wireless clients (192.168.15.*)

    I have several goals:

    make my shorewall server the single dhcp server on the network. I set the dhcp relay function and it appears to work

    disable nat on the wrtp54g so that I don't need to configure port forwarding to get access between my wired and wireless clients.

    I see the option for disabling NAT, which I have done, but I think there are other settings I need to make this work.

    For example, what do I set the WAN address of the 54g to?
    Do I still need dhcp relay set?
    what is the gateway on the 54G now?
    do I keep the LAN setting to 192.168.15.*?
    Do I need to set a static route on the shorewall server?
    Do I need to make a cabling change?
    Is this just a simple switch essentially now, so can I change the lan setting to 192.168.1.*, do I need to change my dhcp scope then?

    minor correction

    the text diagram I showed above should show the wrtp54G coming off of the 'switch'

    fixed it

    Somehow I hosed my wrtp54g during all of this. I can probably get it back, but it prompted me to dig out my wrt54gs from my drawer that had dd-wrt on it.

    it was quite easy to do with that. I did this:

    disable internet connection type
    assign WAN port to LAN
    set lan address to an address on my shorewall routers LAN (
    set the gateway to my shorewall router (
    disable wrt54g dhcp server
    in advanced routing, left it set to gateway mode, although I don't think it makes a difference

    no special routes needed on the shorewall box.

    I'm pretty sure the wrtp54g can be configured similarly, but I think the key is to plug the LAN side of the wrtp into the lan side of the shorewall router, and leave the wan port on the wrtp disconnected.
