Why Run a VPN on Your Router Instead of Each Device

Installing a VPN on individual devices protects only those devices. A VPN on your router encrypts traffic from every device on your network — laptops, phones, smart TVs, game consoles, IoT devices — without installing apps on each one. Devices that do not support VPN apps natively (like smart TVs, streaming sticks, and game consoles) benefit from router-level VPN protection automatically.

The convenience factor is significant. With a router-level VPN, every new device that connects to your WiFi is automatically protected. Guests, family members, and new devices do not need configuration. You manage one VPN connection at the router level instead of juggling VPN apps across every device in the household.

The trade-off is that router-level VPN affects everything. If you need VPN for some activities but not others (like local streaming that requires a domestic IP), you will need split tunneling capability. Not all routers support granular split tunneling, so consider your usage patterns before committing to a router-level approach.

Which Routers Support VPN Client Mode

Not every router can run a VPN client. You need a router with VPN client support and enough processing power to handle the encryption overhead without crippling your speeds.

ASUS routers offer the best consumer VPN client support. Models running the AiMesh or Merlin firmware include built-in OpenVPN and WireGuard client configuration through the admin panel. The setup is graphical and relatively straightforward. ASUS also supports split tunneling natively, allowing you to choose which devices route through the VPN and which connect directly.

Netgear Nighthawk models support VPN client configuration, though the process is less user-friendly than ASUS. OpenVPN is typically the supported protocol, with manual configuration file import required.

OpenWrt and DD-WRT are open-source firmware alternatives that add VPN client support to many consumer routers. If your current router does not support VPN client mode, flashing OpenWrt (where supported) adds WireGuard and OpenVPN client capability. This approach requires comfort with command-line configuration.

ISP-provided routers almost never support VPN client mode. If your provider gave you a router/modem combo, you have two options: put it in bridge mode and use a separate VPN-capable router behind it, or use device-level VPN apps instead.

Step-by-Step VPN Router Setup (ASUS Example)

Step 1: Sign up for a VPN service that supports router installation. Major providers like NordVPN, Surfshark, ExpressVPN, and ProtonVPN offer router configuration files and guides. Download the configuration file for your preferred server location.

Step 2: Log into your ASUS router admin panel (typically at 192.168.1.1). Navigate to VPN > VPN Client. Click "Add profile."

Step 3: Select the VPN protocol. WireGuard is recommended for performance — it handles encryption more efficiently than OpenVPN on most router hardware, resulting in faster speeds. If WireGuard is not available, use OpenVPN.

Step 4: Import the configuration file provided by your VPN service. This file contains the server address, encryption keys, and connection parameters. Upload it through the router's interface.

Step 5: Enable the VPN connection. The router establishes the encrypted tunnel to the VPN server. All traffic from devices on your network now routes through the VPN. Verify by visiting a site that shows your IP address — it should display the VPN server's location, not your actual location.

Step 6: Configure split tunneling if needed. In the VPN client settings, specify which devices should use the VPN and which should connect directly. This is useful for streaming devices (which may need a domestic IP) and gaming (which benefits from lower latency without VPN overhead).

Choosing the Right VPN Protocol

WireGuard is the recommended protocol for router VPN in 2026. It uses modern cryptography, operates with minimal overhead, and achieves significantly faster speeds than OpenVPN on most router hardware. WireGuard's lightweight codebase is also easier for router processors to handle, resulting in less speed degradation.

OpenVPN is the traditional choice with broader router compatibility. It is well-tested and highly configurable but places heavier demands on router processors. On a mid-range consumer router, OpenVPN typically caps at one hundred to two hundred megabits per second, while WireGuard on the same hardware can achieve three hundred or more.

IKEv2/IPsec is supported by some routers and offers good performance with automatic reconnection after network interruptions. It is less commonly supported than OpenVPN or WireGuard in consumer router firmware.

Performance Impact of Router VPN

Running a VPN on your router reduces your available internet speed because the router's processor must encrypt and decrypt every packet. The degree of speed reduction depends on your router's CPU power and the VPN protocol used.

As a general guideline, a mid-range consumer router (dual-core processor around 1.5 GHz) running WireGuard achieves approximately two hundred to four hundred megabits per second of VPN throughput. The same router running OpenVPN may achieve one hundred to two hundred megabits per second. High-end routers with faster processors (like the ASUS RT-BE96U with its 2.6 GHz quad-core) handle VPN encryption with less speed penalty.

If your internet plan exceeds your router's VPN throughput capability, your VPN speed becomes the bottleneck. For a household with a 500 Mbps plan running VPN on a mid-range router, effective speeds might be two hundred to three hundred megabits per second — still fast enough for most activities but noticeably slower than the plan's maximum.

Split Tunneling: Routing Only What Needs Protection

Split tunneling lets you choose which traffic goes through the VPN and which connects directly. This is essential for maintaining performance on latency-sensitive activities while protecting privacy-sensitive traffic.

Route through the VPN: web browsing, email, messaging, file downloads, torrent traffic, and any device you want to protect from ISP monitoring. Route directly (bypass VPN): gaming consoles (latency-sensitive), streaming devices that require a local IP for content licensing, smart home devices that need local network access, and speed tests.

On ASUS routers with Merlin firmware, split tunneling is configured per-device using the VPN Director feature. You assign each device's MAC address or IP to either the VPN tunnel or the direct connection. This granularity is one of the strongest arguments for ASUS routers in a VPN setup.
