This guide will walk you through the steps involved in setting up an OpenVPN server on a pfSense instance that allows you to securely access your home/office network from a remote location and optionally send all of your network traffic through it so you can access the internet securely as well. Setting up your OpenVPN server to access your home or office network gives you full access to all your files on your network.

Install the OpenVPN Client Export Utility: This rule will allow your client to connect to your OpenVPN server from the internet.ĭestination Port Range : Other (1194) 6. To connect to your OpenVPN server from the outside world (i.e., the internet), you’re going to need to open the port your server runs on (1194, in this example) on your WAN interface. Source: Network (OpenVPN subnet you specified earlier. Set below information into their respective field: Create Firewall Rules: 5.1 Firewall > Rules > OpenVPN Verifying the OpenVPN server configuration If you’re only using IPv4, select IPv4 only in the Gateway creation field. I’m using 10.100.100.0/24/24.Įnable Redirect IPv4 Gateway to route all IPv4 traffic over the VPN tunnel. In the IPv4 Tunnel Network field, enter a subnet that is not present on your network to be used as the OpenVPN network’s internal subnet. Server certificate: the server certificate we created earlier. Peer Certificate Authority: Test (we have created earlier) Use a TLS Key and Automatically generate a TLS Key are enabled. Server mode: Remote Access (SSL/TLS + User Auth) Set the below information into their respective field as shown in the screenshot: Creating OpenVPN Server: 4.1 VPN > OpenVPN You’ll be taken to the Certificate Manager, and prompted to input the parameters for your user certificate.Ĥ. You’ll be taken back to the Edit User window.Ĭlick the Add button under User Certificates.
