OpenVPN DHCP leases

[pankaj]

Hi,

I have OpenVPN running on a OPNSense box but when I connect the VPN client, I do not see the IP address of OpenVPN client in the "/var/dhcpd/var/db/dhcpd.leases" file.

I wrote a shell script to monitor a specified subnet within "/var/dhcpd/var/db/dhcpd.leases" file and hence use the script to generate notification using Monit. But since VPN clients are not showing up in "/var/dhcpd/var/db/dhcpd.leases", I am back to square one 

Is there another place to look for DHCP leases of OpenVPN client?
Thanks.
