Router VPNs protect all devices on your network but are limited by router CPU. Use WireGuard for 3-5x faster speeds than OpenVPN. Budget routers max out at ~50 Mbps with OpenVPN; invest in a powerful router or dedicated VPN router for faster connections.

Why Use a Router VPN?
Protect All Devices
Every device on your network is protected, including smart TVs, game consoles, and IoT devices that can't run VPN apps.
Unlimited Connections
One VPN connection on the router covers unlimited devices, bypassing per-device limits.
Set and Forget
Configure once, always protected. No need to remember to connect on each device.
Network-Level Control
Route specific devices through VPN while others connect directly using policy-based routing.
Throughput Benchmarks
Router VPN speed depends heavily on your router's CPU and the VPN protocol:
| Router Class | OpenVPN | WireGuard | Examples |
|---|---|---|---|
| Budget | 15-30 Mbps | 50-100 Mbps | GL.iNet Beryl, basic Asus |
| Mid-Range | 30-50 Mbps | 100-200 Mbps | Asus RT-AX58U, Netgear R7000 |
| High-End | 50-100 Mbps | 200-400 Mbps | Asus RT-AX86U, GT-AX11000 |
| Dedicated VPN Router | 100-200 Mbps | 400-1000+ Mbps | Vilfo, Firewalla Gold |
WireGuard vs OpenVPN on Routers
Protocol choice dramatically affects router VPN performance:
OpenVPN
- Runs in userspace: Higher CPU overhead
- Single-threaded: Can't use multiple CPU cores effectively
- Widely supported: Works on almost any router firmware
- Typical speed: 20-50 Mbps on consumer routers
WireGuard
- Runs in kernel: Much lower CPU overhead
- Efficient crypto: Uses modern, fast algorithms
- 3-5x faster: Than OpenVPN on same hardware
- Requires newer firmware: OpenWrt 21+, AsusWRT-Merlin
Recommendation
Always use WireGuard on routers if available. The speed difference is dramatic-a router that maxes out at 40 Mbps with OpenVPN might achieve 150+ Mbps with WireGuard.

- Set up policy-based routing (optional)
Frequently Asked Questions
Yes, significantly. On a typical consumer router, OpenVPN maxes out at 30-50 Mbps due to CPU limitations, while WireGuard can achieve 100-300+ Mbps on the same hardware. WireGuard's kernel-level implementation and efficient cryptography make it 3-5x faster.
Yes, router VPNs are limited by the router's CPU. Budget routers may only achieve 20-50 Mbps with OpenVPN. For faster speeds, use WireGuard protocol or invest in a router with a powerful CPU. If you have gigabit internet, consider a dedicated VPN router.
Yes, most router VPN setups support policy-based routing. You can configure specific devices or IP ranges to bypass the VPN while others use it. This is useful for devices that don't work well with VPNs like smart TVs, gaming consoles, or banking apps.
Most ISP-provided routers don't support VPN client functionality. Options include: replacing it with a compatible router, adding a secondary VPN router behind it, or using VPN on individual devices instead. Check if your ISP router supports bridge mode.
