how to clear dhcp lease table in 2018

BJohnson

Hello,

I need to clear the DHCP lease table so I can determine whether new hardware is configuring properly.  My network has multiple VLANs.  Will the DHCP toggle trick work for the entire lease table if I only toggle one of the ranges?

Thanks,
B

    Hi BJohnson,

    Toggling the DHCP server from UI will not work, renew the IP address on the machine after setting the lease time in the UTM's DHCP server definition to a lower value. The minimum is 600 seconds (10 minutes). 

    Thanks,
