    Hi there

    Have a network with 2 servers:
    Server A, 2 nics using RRAS, set up to allow VPN access allocating
    192,168,5,10 thru to 20 addresses for VPN connections
    Internal nic 10.0.0.10. (subnet mask 255.255.254.0)

    Server B, 10.0.0.11.

    From a remote site who ip's address are 10.0.0.x subnet mask 255.255.255.0.
    I can VPN onto Server A (using the Wan cards address)and get logged on OK.
    I get allocated an address from the 192.168.5.5 range OK
    Problem: I need to access Server B, cannot do it. I have given the NIC on
    Server B an alternative address of 192.168.5.5 and have set up a static
    route under RRAS on Server A - 192.168.5.0:255.255.255.0:10.0.0.10:LAN
    interface and can ping 192.168.5.5 ok from within the LAN. i know it is a
    routing issue but I am unsure oof what is required

    Any help

    BJ

  2. you may need to enable ip routing. quoted form http://www.ChicagoTech.net
    How to Configure Windows server to Be a Router
    To setup Windows 2000/2003 as a router for a LAN, you need to two network
    adapters. To enable LAN routing. go to Administrative Tools>Routing and
    Remote Access>Action>Configure and Enable Routing and Remote Access, and
    then complete the wizard. Right-click the server for which you want to
    enable routing, and then click Properties>General>Router, check Local area
    network (LAN) routing only, and then click OK.

    I can't see any way that you can get this to work. The basic problem is
    that both machines are in the same IP subnet. As far as TCP/IP is concerned,
    all 10.0.0 addresses are local! No matter what routes you add, you can't
    change that. The traffic will never get to a router. It will try to deliver
    it locally "on the wire" using ARP and hardware addressing.

    Hi Bill
    I tend to agree with you on this - basically I am trying to route to an
    address which the system thinks is on it own subnet

    Any suggestion would be greatly received.

    Will check the article in the meantime.
