Acces webserver on clients from other subnets

    Question

  • Hello,

    I have created a netwrok containing three subnets.

    172.16.1.0 /24

    172.16.2.0/24

    172.16.3.0/24

    I have a webserver (172.16.1.15) but I can only access it from 172.16.1.x.

    I want to access it from the other subnets.

    My DC has 3 network cards, one for each network. I want to route between all networks (every client may ping all other clients from other subnets).

    Can anyone help me how I can arrange this?

    I am using Windows Server 2008R2

    Kind regards,

    Mickey

  • The DHCP server is set as followed:

    Range 1: 172.16.1.20 - 172.16.1.250

    Range 2: 172.16.2.20 - 172.16.2.250

    Range 3: 172.16.3.30 - 172.16.3.250

    NIC1 DC: 172.16.1.1 255.255.255.0

    NIC2 DC: 172.16.2.1 255.255.255.0

    NIC2 DC: 172.16.3.1 255.255.255.0

    Client 1 (Subnet1): 172.16.1.20 255.255.255.0 Gateway: 172.16.1.1

    Client 2 (Subnet2): 172.16.2.20 255.255.255.0 Gateway: 172.16.2.1

    Client 3 (Subnet3): 172.16.3.20 255.255.255.0 Gateway: 172.16.3.1

    Webserver: 172.16.1.15 255.255.255.0 Gateway: 172.16.1.1

    All clients have internet connection and are part of the same domain.

  • Hi,

    Firstly, it is not recommended to set the DC multihomed.

    In addition, since they are not in the same subnet, you need to add static route for them to connect.

    Besides, have you set up your own DHCP server? If yes, how did you configure? I would appreciate it if you can post some results of running "ipconfig/all" on the webserver, DC and clients.

    Best regards,

    Susie
