  • how to configur ip in my network

    Dear..
    i have domain control 2003 and i need to install with it the dns and dhcp
    and have isa server 2006 with 2 nic cards
    so i need to know the true ips i must but it in clients and in domain
    i do this but need someone to correct it if there is anything wrong

    ips for doman controller
    ip:192.168.100.1
    sub:255.255.255.0
    getway:192.168.100.1
    dns:192.168.100.1

    isa first nic (internal)
    ip:192.168.100.2
    sub:255.255.255.0
    getway:.................
    dns:192.168.100.1

    my questions is this confgirations true or not?
    and when i need to configer dhcp it ask me about default getway for client's i want to know if i will but the ip for domain 192.168.100.1

    Ok, I'm having trouble understanding exactly what you mean.. however I think you need to know the gateway you should be giving the DHCP clients.

    I would suspect that, since you have an ISA installation, you would want to use this as the gateway, so you should give all your clients the IP address of the internal (or trusted) NIC on the ISA server - from your provided information ,that seems to be 192.168.100.2


    However.. you'd probably also need to set this as the gateway for the domain controller.
    (Unless of course that's the gateway, in which case this all becomes somehwat more confusing.)

      Question is little bit clear, correct me if i go wrong in solving your query

      Let us assume

      DC
      IP: 192.168.10.1
      Subnet:255.255.255.0
      Gatewau:192.168.100.1
      DNS: 192.168.10.1

      ISA
      one NIC (Internal)
      IP:192.168.100.1
      Subnet:255.255.255.0
      Gateway:
      DNS:192.168.10.1

      Second NIC(It can be natted with Public IP or you can assing live IP)
      In this i assume you have given Live IP to this adapater
      IP: xxx.xxx.xxx.xxx
      Subnetxx.xxx.xxx.xxx.
      Gatewayxx.xxx.xxx.xxx.
      DNS: xxx.xxx.xxx.xxx.

      "xxx.xxx.xxx.xxx" represent the IP given by your ISP provider.

      On all client's machine you have to put gateway as 192.168.100.1 and DNS will be you Internal Server i.e 192.168.10.1, which you have made DC as DNS and remember to set it forwarder to your Public DNS IP provided by your ISP.

      "Gateway is only use to access to other network apart from parent network."

      i hope i have clear the exact query.

        The subnets are different. Make sure they are in the same subnet or setup routing (VLAN's and/or routers) to the ISA box.
        Also make sure you read this article from Jason Jones carefully:
