Restrict users access using MAC address Authentication

[imaddaou]

Dear OpenVPN community,

My goal is to build an OpenVPN solution using MAC address restriction of manual ACL; plus Muti-factor authentication.

I am interested in post_auth script, I was readying about it https://openvpn.net/vpn-server-resource ... -checking/ However, is it available for the community edition of OpenVPN or is it ONLY for Access Server? If it does, please guide me in the right direction, If it's not available for community edition, what are my choices?

Lastly, do you recommend ready solution like OPNsense https://docs.opnsense.org/manual/vpnet.html

I look forward for your response at your earliest conveience; your time and guidance will be highly appreciated.

Thank you everyone!

Imad
