Win2k3 routing between two networks - cross post

    I think I originally posted this in the wrong news group when it should
    be here.

    I am trying to get my Win2k3 server to forward LAN requests for internet
    addresses to my router. I'm a complete DNS neophyte so please be kind.

    Here's what I've got:
    ISP's modem connects to Linksys router. ISP assigns a DHCP address and
    DNS servers. Linksys router's LAN address is 192.168.1.1.

    Linksys router is also serving DHCP for wireless internet access.

    Server with (2) NIC's. NIC1, named "Public Internet" has an IP address
    of 192.168.1.2. NIC2 is named "Private LAN" and has an IP address of
    192.168.2.1. DNS, DHCP and web server are bound to 192.168.2.1.

    I've got a Cisco Catalyst 4006 switch for the private LAN and a several
    servers/workstations inside the private LAN.

    I need to be able to route from the internet to a LAN server and route
    from the LAN to the public internet. I can't seem to do that. When I
    have the LAN network card enabled I can't surf the internet. When it is
    disabled I can.

    Public Internet card: 192.168.1.2/255.255.255.0, gateway: 192.168.1.1,
    DNS 192.168.1.1

    Private LAN card: 192.168.2.1/255.255.2550, gateway 192.168.2.1, dns
    192.168.2.1

    Can anyone help please. If I need to change the topology i have no
    problem doing that. Ultimately I want to have VPN access to the LAN
    hosted by one of the Win2k3 servers through the linksys router. Each
    network works fine independent of each other.

    Thank you in advance.

    Thank you, that worked for the server.

    When I try to use a LAN connected workstation I cannot get to the
    internet. I look at ipconfig /all and get this:

  3. Do you use AD? I wouldn't use the router for a DHCP server or for a DNS
    server - I'd put both those roles on the Windows servers in each location.
    Uninstall IPv6. It's highly unlikely that you need it.<snip>

    You know, I think I was a real knucklehead when I set this up. I made
    this much more complex than I needed to.

    Use the Linksys as the router, assign it a static IP. Pass VPN to server.
    Use the server to serve dhcp/dns/vpn/etc to internal network.

    That way it stays all on one subnet. I don't know why I didn't do this
    in the first place. At any rate, it works now like it should. Thank you
    for your assistance, I appreciate it.

  5. You're moset welcome - glad you got it sorted out. And I love the word
    "knucklehead" - it's underused nowadays. ;-)
