In this article, we will discuss the issue of VPN on a router vs. VPN app installed on a device.
VPN on a device: With a VPN installed on a device, you can only access a VPN connection with that specific device and only when the app is turned on. If you need more devices connected to a VPN, you will have to install the VPN app on every device.
VPN on a router: With a VPN router, you only need a VPN installed on the router itself. Every device then connected to the VPN router will share the VPN connection. You will not have to install an app on any other device.
So, which one to use and when:
Use a VPN app: If you only need a VPN connection on one (or just a few) of your devices and only intend to use the VPN connection sporadically (such as unblocking streaming sites, for example).

Use a VPN router: If you have multiple devices that need a stable and frequently used VPN connection (work computer, office environment with multiple devices, etc.). This way, you won’t have to manually install and set up the VPN app on all devices.
You should also use a VPN router if you have a device that you want to connect to a VPN server alone and never to your regular connection.
A VPN router is also advantageous when you are using an OS with which most VPN apps are incompatible, such as Tails OS.
Below, we will elaborate on how VPN apps and routers work and show you how to set up a VPN router yourself.
Summary and 2023 Update:
This article examines the pros and cons of using a VPN on a router versus a VPN app on individual devices. A VPN on a router allows all connected devices to share the VPN connection, while a VPN app must be installed on each device.
VPN routers are recommended for those with multiple devices needing a stable and frequent VPN connection, while VPN apps are suitable for those needing a VPN on only a few devices and for occasional use.
VPN routers offer increased security, customization, and encryption for all internet traffic but can be expensive and require manual configuration.
Take a look at the diagrams below.
In the first – VPN on a device – we can see a laptop connecting to the internet through a VPN connection. This is the way most consumer VPNs are set up. This system works just fine.
Below we can see how things are set up with a VPN router. Many devices can connect through the same VPN service, which is now handled by the router itself.
Depending on the router operating system (firmware) used, it can be possible to simultaneously connect certain devices to the VPN while having others connect directly to the internet as normal without a VPN.
There are several advantages of running a VPN on your router rather than on each device. One of the main things I like is the level of control and customization over your entire home network when you’re using the higher-end firmware of a VPN router.
With a VPN router, you can connect all your WiFi and wired devices to the internet through the VPN, even devices that don’t support a VPN. This means that the VPN encrypts ALL your internet traffic, and the apparent location of your entire network will be that of the VPN server.
What’s more, your ISP will see encrypted packets and won’t be able to determine whether you’re torrenting on your laptop, unblocking Netflix on your phone, or gaming online through a console.
Using a VPN can help you keep your online activities private from your ISP. This includes unblocking and streaming content from services like Netflix.

This ” set it and forget it ” method is very good for protecting your home network. Still, I would suggest periodically testing the VPN connection using a tool such as DNSLeakTest, rather than forgetting, as VPN connections can go down.
It’s clear that encrypting all your internet activity by default will increase the overall security of your network.
While most websites and services encrypt data between the computer and their servers, not all do, and it’s still possible to discover which services you use, even if the attacker can’t see what you’re sending and receiving.
This is an often-overlooked vulnerability.
Most people will never consider that the services they use could be the first piece of information that an attacker looks for.
This could be the beginning of a spear phishing attack, Where a hacker uses social engineering to specifically target an individual.
In this case, they would start by learning which online services you use so they can create a fraudulent form of contact from that service to steal confidential information.
Of course, this particular method is impossible if you’re using a VPN.
Do remember, though, that simply using a VPN is not a failsafe way to become anonymous online, and anyone who tells you it is, is either lying or has believed a lie someone else has told them. Either way, it’s not true.
There are indeed some disadvantages of VPN routers. The one that will probably put off the most people is the hardware cost.
The basic router you get from your ISP is unlikely to be VPN compatible, nor will you be able to flash it with firmware.
The type of router compatible with a VPN is generally much more expensive, with the most basic models starting at around $50, but can run way higher than that if you want something with a bit more grunt.
If you have a lot of devices connecting to your WiFi at once, your router will need more processing power to keep up with the constant encryption and decryption for the VPN.
This shouldn’t be an issue for most home applications, and a consumer-grade VPN-compatible router should be fine.
Something else worth bearing in mind is that, when running a VPN on your phone or computer, you get the full feature set of the VPN app, which usually supports several VPN protocols and encryption suites, and allows you to alter the configuration quickly.
On the other hand, a VPN on a router requires manual configuration and often only supports OpenVPN (which is the best anyway, at least). Changing the server location on a VPN router is also more laborious.
So how exactly is a VPN router different from a regular router?
A VPN router is just like any other router, but with the capability of running a VPN connection. A special operating system, known as firmware, is required to do this.
All of the following router firmware options mentioned below offer advanced customization and give users many options in addition to running a VPN through the router.
QoS (Quality of service) is a popular feature, available on most custom firmware. QoS allows the network administrator to allocate bandwidth based on internet traffic.
You can, for example, make sure your PS4 connection always has preference over someone browsing the internet, that a specific machine gets more bandwidth than mobile connections, or that P2P downloads are restricted to avoid slowing down the network.
Some routers, such as Netgear, some D-Link and Linksys models, and most enterprise/ business routers come with VPN-compatible firmware straight out of the box.
Still, that firmware is not usually the most powerful in terms of its other features, so many people prefer to install custom firmware such as Tomato, Sabai OS, or DD-WRT.
DD-WRT is probably the most widely used custom router firmware and handles VPN connections very well.
It’s a free, open-source firmware that has a huge online community of helpful DD-WRT users so you can find instructions on how to set up pretty much anything it’s capable of. You do have to do quite a bit of configuration yourself, though.
DD-WRT can be installed at home on a wide variety of routers.
Flashing a router is pretty simple, but if you do it wrong, you’ll probably end up with an expensive paperweight, so if you’re unsure, then it’s best to buy a pre-configured one from Amazon.
Tomato is another free, open-source firmware that can be installed on various routers.
It can handle a lot of very complex processes and has massive customization options but requires a greater level of user knowledge as each feature has to be programmed in.
Tomato can’t be considered a consumer-grade option due to the potential difficulty of set up for non-programmers. It is, however, extremely powerful.
For more information, as well as download links, visit the official Tomato firmware website.
Sabai Technology is a small business with a big name. They care about their work and offer some of the best customer support in the industry. I worked for them for almost two years and can say they’re 100% legit.
Now onto their VPN router firmware – it’s by far the most user-friendly on this list and is easy to set up and use but is not free. Sabai OS (the name of their firmware) is based on Tomato but is preconfigured to get your router working quickly and easily, so you don’t need the expert knowledge to make a regular Tomato build work properly.
Sabai OS has a great Gateways feature that makes it easy to configure which connected devices run through the VPN and the regular internet.
They also sell pre-configured VPN routers that are ready to go straight out of the box. That means there’s no need to risk breaking a router while trying to flash it yourself.
pfsense is a different beast altogether. You can install this OS on an old pc and use that as a highly secure VPN router with loads of extra features such as built-in anti-virus (at the router level, so malware can’t even get onto your device).
Of course, using an old PC would cost a lot of electricity, so I’d suggest getting a purpose-built box or building one yourself.
There’s a large pfsense community scattered across many forums, with many people who build their own routers and give advice. Get started with pfsense here.
When using one of the router firmware builds described above, setting up a VPN is fairly straightforward.
You’ll need your VPN login credentials from your VPN provider. You do still need a subscription to a VPN service.
Many VPN services provide detailed instructions on how to set up their VPN on a router. This usually consists of a list of steps to set up the VPN connection and DNS, install the encryption certificates, and select a server.
Again, this is more time-consuming than simply using the VPN app on your laptop, but it does protect your entire network rather than a single device.
It’s also pretty fun to set up if your into that kind of thing.
