Use fixed IP addresses for tunnelled node clients

    Posted Nov 22, 2022 01:22 PM

    Hello,

    I really like tunnelled node capability for a use case I have; but I need to statically assign the same IP address to clients that will be connecting - this will be for a remote access capability. 


    is there a way I can use tunnelled node in this way? Ensure that each client can use the same IP address every time they connect?

    What is serving out DHCP? You could configure a static DHCP binding so that their MAC address always pulls the same IP within the VLAN you terminate them on (controller side uplink because your tunneling).

    Thanks Dustin,

    was planning on using a Windows DHCP server and having the controller relay the request - but the main thing is to achieve the same IP address for each client so I'll use whatever method suits. 


    that static dhcp binding, is that done within the controller without any external systems like a windows server etc?

    The DHCP binding would be configured on your DHCP server.

    You would do that on your DHCP server. See example below for Windows DHCP. This configuration results in that if the client with MAC address a036d408ea48 requests an IP address, it always receives 10.254.1.38:
    You just need to make sure that the client always ends up in the same VLAN, which is easy to do with tunneled node / UBT / PBT.
