OpenVPN Instances, Peer Certificate Authority

[bobbyb84]

Hi,

I'm about to migrate my legacy server settings to the new instances setup.
My old setup is like. I have sever certificate signed by my own CA.
My clients are using a 3rd party certificate by companies PKI. In the legacy setting I can specify which CA to use to verify the client certificate with "Peer Certificate Authority".

I the new instances setup this configuration option is missing. I can not select which CA to use to verify the client certificates? How can I transfer the legacy setup to the new setup in those regards?

Thanks and Regards
