Delete DHCP lease currently active



  • pfsense 2.3.3

    I want to delete a DHCP lease that is currently active although it looks like you can only delete stale leases at the moment. If that is the case, what is the lease setting for DHCP after a user has turned off WiFi. How long will it keep that address for before allowing the option to delete it or freeing it up to use in the pool?

    just delete the arp entry on pfsense for that IP, and pfsense will then mark the device as off.. The default arp cache on pfsense is 20 minutes I do believe.



  • top man. It shows the expiry time in seconds too.
