disabling NAT specific settings

    Hi,

    I have the following setup:

    DSL modem ----> linux shorewall server ---> switch ----> wired clients (192.168.1.*)
    |
    ---> linksys wrtp54g (192.168.1.2)
    |
    ---> 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?


    Thanks,
    Cliff

    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 (192.168.1.2)
    set the gateway to my shorewall router (192.168.1.1)
    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.
