Is there a way to block an open VPN connection?
Any simple packet filter can block the standard OpenVPN client/server communications.

How does OpenVPN restrict client access to specific IP addresses?
Limiting client access to certain IPs must be done by firewall rules on the OpenVPN tab. If you assign a static IP/subnet (/30) to an OpenVPN client then you put this subnet as “Source” in the firewall rule and as destination the IP addresses this client should be able to connect to.
Why is my OpenVPN client reporting MAC address?
