How many OpenVPN concurrent sessions allowed?

[nqtuanqtuan]

Hi folks,

I have a customer asking how many concurrent OpenVPN sessions the community version of OPNsense would support? If the OPNsense firewalls (HA) are dedicated VPN server.

Is there a reference or calculation based on the specs? For example how many users for 1vCPU virtual OPNsense? 2vCPU? etc.
