Removing 2nd NIC to go to 1 NIC setup

    I have an SBS 2003 Premium using 2 NIC setup with hardware Firewall/Router.
    I wish to move to a single NIC setup. Is it as simple as removing the 2nd
    NIC and rerunning CEICW again? Or are there gotchas here. TIA.

  2. Hi BC,

    It's about that simple - the CEICW will reconfigure you networking. You'll
    need to publish any server resources you want accessible from the internet
    via the external device, and possibly create rules (depending on the
    capability/feature set of the device). If you have ISA installed, the CEICW
    will re-configure it for a single interface installation - which amounts to
    a caching role.

  3. Les is correct however you don't even have to remove the NIC if you don't
    want
    Just disable it in Device Manager

    Hi Les,

    Thanks for the suggestion. I've removed the NIC and started CEICW. When I
    get to the router connection part of the wizard it complains "The IP address
    specified for the local the local IP address of router is not within the same
    address space (subnet) as the IP address and subnet mask specified for the
    network adapter. This will result in connectivity problems. Are you sure
    you want to use the specified IP address for the local IP address of the
    router?"

    Regards
    bc

    I went ahead and ignored the message and after the wizard finished I cannot
    now connect to the internet.

    You need to reconfigure the LAN IP address range in your router to the same
    range as the SBS Lan. Then re-run CEICW and give it the IP address of the
    router as your default gateway.

    Buddy,

    SBS is DHCP server. SBS Scope 192.168.16.0
    Router DHCP disabled. Address 192.168.3.1

    are you saying i have to change the Router to 192.168.16.xxx

    thanks

    Yes, change the router to 192.168.16.1

    If your SBS is on 192.168.16.x with a mask of 255.255.255.0, then it cannot
    comminicate with 192,169.3.x subnet. They have to be on the same subnet now
    that the external NIC is gone.

  9. I usually move the SBS IP to the router default ;-/. Only reason was, I got
    tired of changing out soho routers every year after they crapped out, and
    having to re-configure the router IP each time.

    But since then, I've started buying better routers - currently sonicwall
    150/170. Huge increase in reliability/longevity, and haven't had to reset or
    replace one now in a couple of years of uptime.
