DHCP will only allow 11 static IPv4 reservations

  • **  :-[ UPDATE: The user I was logged into had read only permissions. It would be nice if the GUI gave some kind of error when this is the case.[/b]

    As the subject says… when I try to add any other reservations the GUI acts as though as is well.  When I check the DHCP server config the new reservations are not there and the devices with reservation get an IP from the pool.

    Have tried both restarting DHCP server and rebooting PFsense... No joy  :(

    Is this a known issue?  Is there a work around?

    Version of PFSense in use:
    2.3.3-RELEASE-p1 (amd64)
    built on Thu Mar 09 07:17:41 CST 2017
    FreeBSD 10.3-RELEASE-p17**

  • I currently have 12, but have had more.

  • May be a bit late in response but how big is the DHCP pool or range for dynamic IP's? If it is say from to then the static IP's may be limited to only 11. (Please correct my math if it's wrong) If the pool or range is large then a smaller one should help.

    As static IP's can only be assigned out side of the dynamic DHCP pool or range.

    As mentioned your static or dhcp reservations are outside the pool, if you need more statics then shrink the pool to leave more IPs in the network for static reservation vs being held by the pool to hand to to just dhcp clients.
