How to find OpenVPN DHCP leases on pfSense

[aldomoro]

Hello

I need to find who is connected to our OpenVPN via IP address 10.0.179.104 without waiting he is connected. Is anywhere a table of reserved IP addresses for OpenVPN clients?
Thank you

You've already concluded that you didn't have a DHCP server for the 'OpenVPN' (server) interface.

That's because the OpenVPN server handles the IP allocation itself.
You have giving it a network, like :

The server itself uses 192.168.3.1 as the network gateway.
All the other IPs, starting from .2 to .254 will be given to the connected OpenVPN clients.

Like :

If you are willing to dive into the OpenVPN server options and settings (good luck ) I guess you will find a way to assign "this-openvpn-client" to "that IP" so that every connecting client will alsways get the same network IP.

Thank you @Gertjan
At the end I made a report in Eset inventory and found all historically used IP addresses and I found my sinner

We use Eset antivirus and it has own administrator console called Eset Protect where I can see inventory of all computers. So I created a report that show me all computers and all historically used IP addresses no matter if they are used on OpenVPN adapter or LAN adapter.

Ok, thank for the feedback.

I've no 'Eset', and said goodbye to the 'antivirus' world many years ago.
I use 'pfSense' as my network inventory tool
