How to Set Up a VPN for Router in 2025 (The Useful Guide)

Tired of setting up a VPN on every single device? Learn how to protect your entire home network by installing a VPN for router.

Quick Answer: Can You Put a VPN on Any Router (VPN for Router)?
Yes, but your router must support VPN client functionality, either natively (like many ASUS or Netgear models) or by installing custom firmware like DD-WRT. The process involves logging into your router’s admin panel, uploading configuration files from your VPN provider, and activating the connection.


The Universal Router VPN Problem (VPN for Router)

Imagine a world where every device in your home—your gaming console, smart TV, weather station, and even your smart lights—is automatically protected by a VPN without you ever having to install an app. This isn’t a futuristic dream; it’s entirely possible by configuring your VPN at the router level.

The challenge? Most standard ISP-issued routers don’t support this feature out of the box. This leads to widespread confusion, as seen by this common question from Reddit user General1993:

“Yes it’s definitely possible, many modern routers can be configured to run a VPN directly which means all connected devices are automatically protected. You just need a compatible router and your VPN’s configuration files.”

This simple answer unlocks a world of whole-home privacy. Let’s dive into the real-world advice from users who have successfully turned their routers into VPN powerhouses.

Reddit’s Real-World Router Setup Advice

1. The Custom Firmware Power-User Method (VPN for Router)

For those with older or more basic routers, the path to VPN functionality often involves custom firmware. As one seasoned user explained six years ago, a solution that remains perfectly relevant today:

“Yes, if you can install something like DD-WRT or OpenWRT on your router you can set up VPN configuration. Also look at setting up a pfsense router which could run VPN directly. There are a few other ways to do this as well so you have many options.”

Why This Works: DD-WRT and OpenWRT are open-source firmware that replace your router’s stock software, unlocking advanced features like a built-in VPN client. A pfsense router is a dedicated firewall device that offers enterprise-grade control, including powerful VPN capabilities.

2. The Speed & Hardware Question (VPN for Router)

A major concern for users is whether a router can handle the encryption overhead of a VPN without destroying their internet speeds. One user pointed out a common limitation with smaller travel routers:

“Beware though, that VPN speeds are slow. With that router in particular… does pull roughly 15-20mbps.. I believe that’s the typical throughput for VPN routers…”

But another user, Youknowintheman, provided a crucial counterpoint that highlights the importance of modern hardware:

“Some routers have hardware acceleration for cryptography these days, which leads to much better speeds. I’ve done 220Mbit on an Asus RT86-U… with Merlin.”

The Takeaway: Your router’s CPU is critical. For high-speed VPN connections, you need a router with strong hardware and, ideally, cryptographic acceleration.

3. The “Why It’s Awesome” – Granular Control (VPN for Router)

Once set up, a router-level VPN offers control that desktop apps can’t match. User completion97 highlighted a killer feature: the ability to route specific devices or websites outside the VPN tunnel.

“Although you can also route traffic… through the vpn (or one vpn out of many) or just straight out the WAN. For example some sites block me when I try to access them through a VPN so I have those sites routed not through the VPN and only those sites.”

This means you can have your Smart TV stream international content through a VPN while your work computer connects directly to the internet for maximum speed and access, all simultaneously on the same network.

4. A Modern Success Story (VPN for Router)

Finally, a recent post from user Fit-Interview-3886 confirms that the process is more accessible than ever, thanks to manufacturers building in support:

“Yeah, I do this at home. It’s totally possible, but your router has to support VPN client mode…not just VPN passthrough. I use an Asus router with built-in OpenVPN support, so I just uploaded my VPN provider’s config file, entered my login, and the whole network goes through the VPN automatically.”

This is the ideal scenario: a consumer-friendly router with native VPN client support, making setup a matter of a few clicks.

Frequently Asked Questions (VPN for Router)

Q: Will a VPN for router slow down my entire internet?
A: Yes, typically by 20-50%, due to encryption overhead. The impact is less noticeable on powerful routers with hardware acceleration.

Q: Can I use my normal internet and VPN at the same time?
A: Yes! Through a feature called split-tunneling (on supported routers), you can designate specific devices or websites to bypass the VPN.

Q: What’s the difference between a VPN client and VPN passthrough?
A: VPN client mode allows your router to create a VPN connection. VPN passthrough allows devices behind the router to create their own VPN connections—it does not mean the router itself is using a VPN.

Q: My router doesn’t support VPNs. What are my options?
A: You can flash custom firmware (if available), purchase a pre-configured VPN router from brands like FlashRouter, or use a plug-in travel router (like GL.iNet) that has a built-in VPN client.
