In PfSense, while when needed expired DHCP leases will be reclaimed, one may want to manually clear expired leases. From DHCP status you can go to ‘Show all configred leases‘ and click ‘Delete lease’ one by one, or you can use this method to clear them quicker.
- Go to Diagnostics then Edit File
- Copy the following file path: /var/dhcpd/var/db/dhcpd.leases
- Click Load
- Now highlight and delete the blocks of leases you want to delete
- Click Save when finished
