Can I login into Domain server throught NAT/PAT device?

Discussion in 'Server Networking' started by faustino Dina, Nov 25, 2003.

  1. Hi,
    I'm trying to use a spare Barricade (SMC7004VBR) Cable/Dsl Router for
    segmenting the LAN in substitution of a two NICs WindowsNT server. The
    problem is that the barricade does NAT (or actually PAT - port address
    translation). Then the PCs (Windows 98) that are located behind the
    barricade are seen as an unique IP address: the IP of the Barricade's
    internal lan NIC. Apparently it causes that these PCs couldn't login into
    the domain server (Windows 2000) locate outside the Barricade.
    Is it any way I can make these PCs to login into the domain server despite
    the NAT/PAT translation?

    Thanks in advance

    Can't you turn off the NAT/PAT ? It is only required if you use the
    router as an Internet router. It is not required for a LAN router. You
    obviously don't need it, because NT4 didn't have it!

  3. Can't you turn off the NAT/PAT ?
    It's just the point! We can't find the way to disable NAT on the Barricade.
    Does anybody knows how to do that?

    Thanks

  4. Google for "SMC7004VBR" and see the instructions.

    http://www.smc.com/drivers_downloads/library/7004VBR_MN2.pdf

    I'm not reading anything on page 22 to "turn off" NAT, though the
    documentation does mention something about Port-Triggered forwarding for
    "Special Applications" -- seems like it's designed to poke a hole through
    the NAT. Try that.

    I have a different SMC router (SMC7004AWBR) and it looks like you can
    disable the NAT by turning off the "Advance Hacker Monitorig and Logging"
    option under Advance/Firewall.

  6. I'm not reading anything on page 22 to "turn off" NAT, though the
    We already tryed but it doesn't works. It doesn't disables PAT

    Thanks for your response

    Have you tried asking SMC? Perhaps they could even help you out with a
    firmware upgrade (if needed).
