Help setting up DHCP superscope RRS feed

  • Question

  • Hi,

    We currently have the following setup:

    IP range 192.168.1.1 - 192.168.1.255

    Gateway 192.168.1.2 (Draytek router)

    DNS/DHCP 192.168.1.4 (AD server is Win 2008 R2 SP1 - single NIC)

    We configured a DHCP superscope to add the 192.168.2.x range

    Clients are picking up IP addresses fine from the new scope but they cannot see the 192.168.1.x range on the LAN

    I've been reading many discussions on setting this up but unable to get it working so far. I get the impression that something needs configured on the router but don't know what...

    Thanks in advance,

    Colin

              It seems you have already configured relay agent.

    1. 2.x range need a gateway to forward traffics to other subnet.Please set it on the router.For more details,contact your router’s vendor.
    2. As a  workaround,you could change the subnet mask to let the 1.x and 2.x into one subnet.For example,255.255.254.0.

  • Are your DHCP server and DHCP clients in the same subnet?

    If DHCP server and DHCP clients in different subnets, we need to set up DHCP relay agent between the two subnets.
