Running out of IP addresses for clients

Post by gio007 » Thu May 12, 2022 4:46 am

Greetings,

I have an old OpenVPN server (2.3.4) running on an Ubuntu system. The address space 192.168.22.0/24 has been configured to issue IP addresses for VPN clients which is working fine so far.

However I've almost run out of IP addresses, where the last assigned IP address is currently 192.168.22.242

Is there is clean method for revoking/deleting old users/keys to free up keys and user profiles (and re-use previously used IP addresses in the private address space) ?

Thanks,

John
