How to Set Up and Use NordVPN on pfSense (Updated 2022)
pfSense is an open-source software distribution that can turn a computer into a dedicated router/firewall. It usually operates on a virtual machine or a dedicated physical computer. It is FreeBSD-based, which means it belongs to the family Unix-like BSD distribution. Using a VPN on pfSense enhances its abilities to protect your devices. This article takes a deep dive into configuring NordVPN on pfSense.
Setting Up NordVPN on pfSense
pfSense has different versions, but the latest one is the 2.5.0 version. This new version has an in-built WireGuard VPN client.

Frequently Asked Questions on Setting up and Using NordVPN on Pfsense
Will using NordVPN on Pfsense make me completely anonymous online?
No, there is nothing that can make you completely anonymous online, except you isolate your computer and not connect to the internet. While you cannot achieve a hundred percent anonymity, NordVPN has privacy features that can give you a high level of anonymity, such as Double VPN, Tor over VPN, and a watertight zero-log policy.

In addition, you will discover there are not many VPNs that can work on Pfsense because of its complex configuration process. Furthermore, almost all free VPN services have limitations on speed, bandwidth, server network, etc. Using NordVPN on Pfsense is way better than using the best free VPN service.
Will using NordVPN on Pfsense protect me against malware?
It depends on the sophistication of malware. NordVPN can never be an alternative to an anti-malware application. The best NordVPN can do is protect you from basic network threats that look to infiltrate your network or ads that contain malware. Its CyberSec feature blocks unwanted ads and known malicious sites. It cannot prevent advanced malware with sophisticated techniques. It is better to get a standalone anti-malware software than depend on NordVPN for protection.
