openvpn setup

Hi there.

I have been searching the forums and the net but can't find a solution to my issue. I want to start monitoring clients servers. Currently i have a openvpn server at work using untangle firewall. It works nice when I connect my house and work together. Now I'm trying to do so for the clients by just loading the config into the Proxmox server. if it's not possible then how can I have remote access to the clients without having a static ip or a dedicated line to client.

Thanks
