    DHCP Table Question

    by alittle1 ·


    DHCP Table showing multiple IP’s to some devices. Some devices show up anywhere from 3 to 20+ times in the DHCP Table on the firewall. Seems to be a new behavior.

    The way it shows up is Device1 with IP and mac then the same name Device 1 with a second IP and no mac showing additional times. Only for a few devices. Have had one device take 34 IP’s and others take 3. This fills up the DHCP table quickly and no more leases can be given.

      In reply to DHCP Table Question

      I found what was going on. Somewhere in our process the DHCP must have been set to a long lease time. Some of the IP’s were in use by other DHCP clients that were showing a renewal date in 2030 Once these were manually renewed the DHCP table started looking correct. I believe this is because the client checked and received the answer back that the IP was taken, just as if it was a static IP used that was in a DHCP range.
