How Openvpn from public internet can utilize pfblockerNG?

[bthoven]

I installed pfblockng and it works fine with local devices. I also installed openvpn server and I can connect to it from public internet. However, I expect the openvpn connection to utilize pfblockerng filter; but it's not.

What additional setting I need to make?

Thank you.

Update: I finally solved the problem by just adding my pfsense IP (192.168.2.1) in the openvpn server advanced setting-->DNS server 1.
No need to regenerate client export ovpn file.
