    Hey, maybe there are some networking gurus here. I'm still fooling around with hardware trying to get to work but heres the situation:

    quick sketch: http://spamdre.com/sketch.jpg

    Internet ->
    Modem ->
    Linksys Router #1 (192.168.1.1)
    • Computer 1 (xavier)
    • Netgear gigabit switch
      • Linksys Router #1 (192.168.1.1)
      • Computer 2 (zim)
      • Computer 3 (zen)
      • Computer 4 (aurora)
      • Linksys Router #2 (192.168.1.2)
        • Server 1 - Files server (spamslayer)
        • Server 2 - dhcp, pxe boot server (spamserver)


    NOTE: Linksys Router #1 is the DHCP.
    I want to run my own DHCP server (so i can pxe boot machines on the network) -- thats where Server 2 dhcp comes into play (see below for the problem).

    Ok, so thats the current layout.

    Problems:
    Linksys Router #1 dhcp is now disabled.
    Server 2 is now on and should be the dhcp server.
    when server 2 is connected to linksys router #2 it cannot assign IP's to computers connected through Linksys Router #1 nor can it pxe boot machines connected to linksys router #2.

    when server 2 is connected to netgear switch it can assign IP's to computer connected through linksys router #1 but not to linksys router #2. BUT, machines on the switch can pxe boot.

    There has to be a better way to setup the network if anyone can provide some insight I'd greatly appreciate it

    EDIT: Thinking of setting it up like this: http://spamdre.com/newlayout.jpg with both routers in "Router Mode" and dhcp disabled of course, since server 2 will be the dhcp.

    Oh my lord what a mess!

    Clearly what needs to be done here is

    Internet ->
    Modem ->
    Computer 1 (xavier) (192.168.1.1)(esx server)
    Computer 2 (zim)(vmware)
    Computer 3 (zen)(vmware)
    Computer 4 (aurora)(vmware)
    Server 1 - Files server (spamslayer)(vmware)
    Server 2 - dhcp, pxe boot server (spamserver)(vmware)

    If more than one person requires use of a computer, I suggest you virtualise them too

    <---- not an network guru
    Can you set the two routers up in a switch mode (maybe called bridge mode)? From what I remember from school days of yore, you won't be able to dhcp through a router since dhcp requires broadcasting which routing prevents (but switching doesn't!)

    speaking of truly epic networks.....
    ..it's safer here.

      If the router gives you lip, flash it with Tomato or DDWRT. It's the only solution.

        What Baz said. DHCP requests won't traverse between your 2 subnets like that.

        From you 2nd drawn diagram, you'll have 4 things there that'll function as a DHCP server (Modem, 2 Routers, Server), so be sure to only use one for proper functionality with PXE, or any network for that matter.


        I would suggest

        Internet > Modem > Router #1 > Switch + Everything else.

        Disable DHCP on Router #1
        Use DHCP on the PXE Server for all your computers.
        Don't use Router #2 (unless it's setup to function like a switch)


        The other option.

        Internet > Modem > Router #1 > Switch + Everything else.

        Flash your linksys router to DD-WRT.
        Use that router as the only DHCP server.
        Set the 2 DHCP options needed for PXE boot and point them to your TFTP server.
        Don't use Router #2 (unless it's setup to function like a switch)

          Thanks for the help everyone!
          I set it up similar to what westy said; only I used tomato firmware since I have a third router that uses tomato and I was wanting to wirelessly add it into the network
          So Router #2 and #3 are set to act as switches.
