Multiple LAN IP range



  • I have not done this BUT Just thinking the possibility.

    What if, I have my LAN interface ip range set to 10.0.0.1/24
    Then, I also have alias group1 with ip range set to 10.0.2/24
    Then, I also have alias group2 with ip range set to 10.0.4/24
    Then, I also have alias group4 with ip range set to 10.0.6/24
    Then, I also have alias group5 with ip range set to 10.0.8/24
    Then, I also have alias group6 with ip range set to 10.0.10/24
    All IP range are allow to have internet access on LAN firewall rules.

    I set group of computers to have ip range of LAN and group1 to group5.
    So it is expected that only ip range 10.0.0.1/24 will be the DHCP ip range.

    1. So my thought is, is LAN and all the GROUP alias will have internet connection ?
    2. Since LAN and Group aliases are on different IP range, even if they are on same LAN interface, can I make of LAN firewall rules to permit traffic between those groups ?


  • i dont understand what you are wanting todo.....
    but whatever it is, its wrong, it wont work, its borked®

    a) don't use multiple ranges on the same interface (you can use vlans)
    b) subnetting doesn't work like you think it does (http://study-ccna.com/subnetting-explained/)



  • @ravegen What you are doing maybe called SEGMENTING, or running multiple LAN subnets, and any time you hear that, it may become a Pandora box. I mean you may have a valid reason to do so, but just be aware, u maybe chewing more than u can handle.

    Yes, multiple segments can be created via a firewall box with multiple LAN NICs, or in your case using a VLAN capable switch most likely.

    Yes DHCP will handles all those segments just fine.

    How many clients aprox are we talking about that you contemplating doing this?
