Resolved - DHCP - Interface TABS (Noob mistake)



  • HI,

    I have an Odd problem. Created and additional interface from Physical and the DHCP server does not display a new tab for the newly created interface. the Only interface that is currently showing is LAN. In reality, I experience the same behavior whether the interface is physical or a virtual from (bridge, lagg or VLANs)

    i am running 2.3

    Check the subnet mask you set on the new interface. If you accidentally set it too small, say a /32 which is only a single address, then the firewall can't do DHCP on that segment.



  • @Jimp,

    Thanks for the suggestion. Was so focus on a bigger problem that missed the subnet mask. Thanks



  • I totally fell for this too. It defaults to a /32 subnet, so if you aren't paying attention…. Yeah. Three days on google to figure this out.



  • Yes, thank you. I fell also into this trap. Default Address Space was /32 and I didn´t see it. Trying and searching for 4 hours…
