How to set up a VPN connection on your Asus VPN Router

  • 21st Nov, 2018

Why should I use a VPN router?

There are a number of reasons why your might want to connect to a VPN server using a hardware router: The router allows you to connect devices to the VPN which otherwise have no VPN functionality at all (Smart TVs, gaming consoles, Google Chromecast, Apple TV, Amazon Fire etc.). A VPN router even lets you connect all your home devices to the VPN at once. Even for advanced users, setting up a VPN router can be a challenge. That’s why we have developed the Shellfire Box. This tiny, pre-configured VPN router makes your connection to Shellfire VPN a plug & play experience. It comes with a easy-to-use user interface. With the Shellfire Box, switching to a VPN server in another location is a matter of a few clicks.

There also are a few downsides to using the Shellfire Box. For demanding users, it might simply be too slow. With its download speeds capped at 15 Mbit/sec (due to CPU power), it is good enough forvideo streaming in 1080p HD quality and most regular internet activities, but the pro user might feel slowed down or restricted. Also, the Shellfire Box can only be used with Shellfire VPN. By using a more expensive hardware router with stronger CPU power, users can enjoy higher download speeds and may feel less restricted than with the Shellfire Box. Many routers will also offer additional perks like 5 GHz Wi-fi and external antennas for better coverage.

While most home routers do not offer the possibility to act as a VPN client by default, many can be upgraded with this functionality. This is usually done by flashing the router with a 3rd party firmware. Firmware is available from open source projects like OpenWRT, dd-wrt or Tomato. However, we do not recommend flashing your router’s firmware unless you know 100% what you are doing: Flashing the firmware might void your warranty and could leave your router in a permanent “bricked” state if done wrong. We found out that among the many high performance VPN routers available, those from Asus come with great VPN support out of the box. They may need some additional tweaking to setup compared to the Shellfire Box, but if you’re into the game of high-speed encrypted internet access, they’re our recommended manufacturer to buy from. For this reason, this guide will focus on setting up a VPN connection using Asus routers which are able to act as an OpenVPN client using the pre-installed firmware (no flashing required!).

Which Asus router should I buy for VPN?

Asus has a wide range of routers with VPN capability available. The choice of a model depends on your budget and on your personal requirements. If you are on a tight budget, the Asus RT-AC58U might be the right choice for you: It comes equipped with a Quad Core CPU running at 710 MHz, 4 Wi-fi antennas and operates at both 2.4 and 5 GHz. If you need even more power and are ready to spend a bit more, check out the Asus RT-AC68U or even the Asus RT-AC88U. The CPUs of these routers are clocking at 800 MHz and a whopping 1.4 GHz respectively. Since VPN encryption is rather CPU intensive, a higher CPU clock speed will usually result in faster download rates over the VPN.

Adding more CPU cores does not really help in achieving better download speeds. Any router with a CPU clocking between 500 and 800 MHz should be fast enough for streaming 1080p HD video. If you are looking for a router with enough power to stream videos in 4k resolution over a VPN connection, you’ll need at least 1 GHz.

What else do I need for my VPN connection?

You need a Shellfire VPN Premium or Premium Plus account in order to download the required config file. If you bought a Shellfire Box, you already own a Premium Plus account. Visit and log in to your user account. Open the quick access bar at the top of your screen and select your VPN account.

Setting up your Asus router to connect to the VPN

  1. Now let’s suppose that you have just unboxed your brand new Asus VPN router. The first thing you need to do, is of course connect it to a power outlet and to your internet connection through its blue Ethernet port. Once the blue LEDs have stopped flashing, you should be ready to connect to your new router. You either connect through Wi-fi or using an Ethernet cable. Once connected, your browser should automatically redirect you to where you will be presented with a setup wizard. First things first, let’s set up a secure password to protect admin access to your router and hit “Next”.
