Step 1– Create Certificate for VPN server
1. Login to the web admin(Firewall)
2. System>>certificate manager>>CAs
3 Press Plus button
4 Give it descriptive name
5 Next you can either Import an existing CA you might have or create a new one. If you have an existing cert paste it into the box. Otherwise choose Create an Internal Certificate Authority and fill in the information below.
Once thats done we need to create our certificates for the OpenVPN server as well as any users we want to connect.
1. While still in System –> Cert Manager, click the Certificates tab
The process for creating a Cert for the server and users are almost identical.
2. In the Method — “Create an Internal Cert”
3. Descriptive name— specify server/username
4. In the Certificate Authority drop down choose the CA you just created.
5. In Certificate Type drop down specify whether this Cert is for the server or a user.
6. Fill out the rest of the info for location
7. Repeat process again for other users keeping in mind the OpenVPN server (pfsense) must have its own cert as well as any users. Create as many certs as you need based off the original CA created earlier
