Using OpenVPN for a remote access VPN is easy and secure. Clients areavailable for many different operating systems, including Windows, Mac,Linux, Android, iOS, and even ChromeOS. This document will walk throughthe basics of a remote access OpenVPN configuration.
Unknown. This How-To article is designed to quickly show how to setup an OpenVPNremote access VPN on the pfSense® router, and is not meant to be complete.It should only be used to give a general idea of the functionality andwhat is possible. OpenVPN is much more advanced than the setup beingdemonstrated.
OpenVPN access server is a tool that allows for the rapid installation & configuration of a VPN server. It is commercial software however the ‘free’ license allows for 2 concurrent connections. A master Certificate Authority (CA) certificate and key, used to sign the server and client certificates. OpenVPN supports bidirectional authentication based on certificates, meaning that the client must authenticate the server certificate and the server must authenticate the client certificate before mutual trust is established.

This guide is brief, and omits important considerations.Consult the OpenVPN chapter in the pfSense Book rather than relying onthis entirely.

OpenVPN Wizard¶
An OpenVPN remote access VPN can easily be configured using the wizard,as follows:
Navigate to VPN > OpenVPN and Click the Wizards Tab to start thewizard.
Authentication¶
Choose the desired Authentication Settings. Most commonly this is set toLocal User Access.
- With Local User Access, users defined under System > UserManager
- RADIUS and LDAP are possible, with appropriately defined settings,as covered here: Authenticating OpenVPN Users with RADIUS via Active Directory.
Click Next
Certificate Authority¶
Fill in the fields to Create a new Certificate Authority
- Descriptive Name - Used as the Common Name (CN) for the CA. Donot spaces, punctuation or special characters (ex: ExampleCoVPNCA)
- Key Length - Default is OK, the higher the better but will usemore CPU.
- Lifetime - Default is OK, but can be lowered if it must bechanged out more often.
- Country Code, State/Province, City, Organization -Enter values for this location/company.
- E-mail - Used as a reference on the certificate, does not receiveany mail from the system.
Click Add New CA
Server Certificate¶
Fill in the fields to create a new Server Certificate. SimilarFields as CA entry, most of the fields carry over and do not needchanged.
Click Create new Certificate
OpenVPN Server Configuration¶
Now for the biggest part: Enter the configuration for the VPN server.
There are many options here, most explained on the page, but the keyitems to enter are:
- TLS Authentication – Leave this checked, along with the boxunderneath to generate a new key. Using a TLS key is technicallyoptional, but highly recommended. Some OpenSSL attacks such asHeartbleed have been mitigated by the use of a TLS key.
- Tunnel Network – Should be a new, unique network that does notexist anywhere in the current network or routing table.
- Local Network – The network here on the server that the clientswill need to reach, for example 192.168.1.0/24
Note
On pfSense software version 2.3, the Topology choice is alsopresent in the Wizard and it defaults to Subnet. Read theassociated text on the page in the unlikely case this option is notdesirable for a given deployment.
Other values can be set as desired and are a matter of preference.Settings such as compression, DNS, NetBIOS, and so on.
Click Next.
Firewall Rules¶

The next screen offers the choice to add firewall rules automatically.For convenience, check both unless the rules will be managed manually.
Click Next
End of the Wizard¶
Click Finish to exit the wizard and the new settings will be savedand applied automatically.
Verifying the Setup¶
Look at firewall rules (WAN and OpenVPN tabs)
- WAN tab rule should pass from any to the OpenVPN port on theWAN address Modbo 4 0 installation manual.
- OpenVPN tab rule should allow anything from any/to any
Adjustments¶
Some settings are not presented in the wizard but might be a better fitfor some situations than the defaults chosen by the wizard.
Server Mode¶
The OpenVPN Server Mode allows selecting a choice between requiringCertificates, User Authentication, or both. The wizard defaults toRemote Access (SSL/TLS + User Auth). The possible values for thischoice and their advantages are:
- Remote Access (SSL/TLS + User Auth)
- Requires both certificates AND username/password
- Each user has a unique client configuration that includes theirpersonal certificate and key.
- Most secure as there are multiple factors of authentication (TLSKey and Certificate that the user has, and the username/passwordthey know)
- Remote Access (SSL/TLS)
- Certificates only, no auth
- Each user has a unique client configuration that includes theirpersonal certificate and key.
- Useful if clients should not be prompted to enter a username andpassword
- Less secure as it relies only on something the user has (TLS keyand certificate)
- Remote Access (User Auth)
- Authentication only, no certificates
- Useful if the clients should not have individual certificates
- Commonly used for external authentication (RADIUS, LDAP)
- All clients can use the same exported client configuration and/orsoftware package
- Less secure as it relies on a shared TLS key plus only somethingthe user knows (Username/password)
Certificate Revocation¶
Compromised certificates can be revoked by creating a CertificateRevocation List (CRL) in System > Cert Manager on the CertificateRevocation tab, adding the certificate to it, and then selecting thatCRL on the OpenVPN server settings.
Adding a User with a Certificate¶
If the mode has been left at the wizard’s default or on a mode thatincludes local user authentication, a user must be created in the usermanager.
- Navigate to System > User Manager
- Click To add a user
- Fill in Username
- Fill in Password / Confirm password
- Check Click to create a user certificate.
- Fill in the Descriptive Name as the username
- Choose the appropriate Certificate Authority
- Click Save
OpenVPN Client Export Package¶
The OpenVPN Client Export Package allows exporting configurationsformatted for a wide variety of platforms. It also allows exporting apre-packaged Windows installer executable which includes theconfiguration bundled inside for a painless client installation.
Installing the OpenVPN Client Export Package¶
To Install the OpenVPN Client Export Package
- Navigate to System > Packages, Available Packages tab

- Set any desired options in the upper section – The defaults aregenerally OK
- Find the user in the list at the bottom of the page and select theappropriate configuration type to export.
The Windows Installer choices are the most common. The “Inline”configuration choices are best when using a current client that isn’tlisted. Some older clients may not fully understand these, but olderclients should be upgraded as soon as possible.
There are links to many commonly used clients at the bottom of theClient Export package page
Wrap Up¶
The VPN setup on the firewall is complete. Install the client and/orimport the new configuration into an existing client, connect and try itout.
