DHCP Service does not show on VLAN Interface



  • Hi Folks,

    I have a PFSense box running on a laptop with one interface. I've setup VLANs for connecting to the internet and VoIP networks etc.

    I see and have configure the DHPC service on the main interface but I don't see any extra tabs in the DHCP service for the VLAN interfaces.

    The main interface is em0 which has a tab in the DHCP service and works as expected but I don't see any tabs for em0.3 or em0.10 even though I assigned a static IP to these interfaces.

    Any help would be appreciated.

    Cheers,



  • You have to enable the interface before you can enable a DHCP server for it.
    Unfortunately you can assign a static IP to the IF without having to enable it prior.


  • LAYER 8 Netgate

    Check the netmask on the interfaces themselves. You probably want /24 there not /32.



  • If an interface has too small a netmask to be used with DHCP service is it disabled automatically then (or even unavailable)?


  • LAYER 8 Netgate

    Yes.



  • Thanks for all your suggestions. The problem was when I assigned the IP the default netmask was set to 32 which I did not notice. I've updated the netmask to 24 which has solved the issue.

    Thanks again everyone for your help :).
