How to set up and configure an OpenVPN Server on Ubuntu

I followed the tutorial https://www.digitalocean.com/community/tutorials/how-to-set-up-and-configure-an-openvpn-server-on-ubuntu-20-04 My server is ubuntu-20-04 as well as my CA server. All are up to date.

Step 11 — Creating the Client Configuration Infrastructure The make_config.sh introduces tls-crypt into the client1.ovpn configuration file. RE: sudo openvpn --config ~/client-configs/files/x530.ovpn

I believe my error: Options error: --tls-auth and --tls-crypt are mutually exclusive I could change the make_config.sh script, to remove all occurances of tls-crypt, is that correct?

Thanks for any help, Don

Hi @dwbauer,

This is a commonly faced issue. --tls-crypt also includes authentication, and thereby makes --tls-auth redundant. Having said that, it’s up to you which one to use.

Additionally, once you decide which to use, you need to pick just one. The catch is that unlike encryption, the server and client profiles must match in their usage of tls-auth or tls-crypt.
