Assign static IP for multiple devices with the same user

[Paze]

Hi guys,

I have set up a OpenVPN on my pfsense, very basic.

Now I have multiple devices (10-20) that are logging in automatically via VPN if they boot up.
I need to either assign the same (unique) address to those clients or give them DNS names (which requires static ip at the end i guess).

As all devices are using the same vpn user to establish the connection, I cant use the client overrides function.
Also, I dont want to edit every config from the clients to assign a unique IP address to them.

We are working with automatisation, so we need to keep the manual configuration as low as possible.

Im really thankfull for every advise on how to achieve my goal.

Thanks.
