How to Install a VPN on a Router (Step-by-Step + Firmware Notes)

Step 1: Check If Router Supports VPN

Most routers can’t run VPN client software.

• Consumer ISP routers (the one your internet company gives you) usually don’t support VPN installs.
• Aftermarket routers (like ASUS, Netgear, Linksys) often do.
• Check the router’s specs page or admin panel for “VPN Client” or “OpenVPN” options.

👉 If your router doesn’t support VPNs, you have two options:

• Buy a pre-configured VPN router (ExpressVPN and FlashRouters sell them ready-to-go). If you need a travel router that supports VPN.
• Install custom firmware (DD-WRT, Tomato, or OpenWrt) — this gives you advanced VPN support but requires more technical steps.

Step 2: Choose the Right VPN Protocol

Most providers give you configuration files. Popular options:

• OpenVPN – The most common and reliable option, supported by many routers.
• WireGuard – Newer, faster, supported by NordVPN and Surfshark on certain routers.
• IKEv2/IPSec – Sometimes supported but less common on routers.

Step 3: Log Into Your Router’s Admin Panel

• Open a browser and type your router’s IP address (often 192.168.0.1 or 192.168.1.1).
• Enter your admin username/password (check the back of the router if unsure).

Step 4: Upload VPN Configuration

This step varies by firmware:

🔹 ASUSWRT (ASUS routers)

• Go to Advanced Settings > VPN.
• Select VPN Client tab.
• Upload the .ovpn config file from your VPN provider.
• Enter your VPN username/password.
• Apply settings → connect.

🔹 Netgear / Linksys stock firmware

• Some newer models have a VPN Client option under Advanced > VPN.
• If not, you’ll need custom firmware like DD-WRT or Tomato.

�� DD-WRT (custom firmware)

• Go to Services > VPN.
• Enable OpenVPN Client.
• Paste in the config file details (server address, port, protocol).
• Enter credentials → save → reboot.

🔹 OpenWrt

• Install the OpenVPN or WireGuard package via the software manager.
• Upload config files via the web UI (LuCI).
• Apply and restart.

Step 5: Connect Devices

Once your router VPN is running:

• Every device connected via Wi-Fi or Ethernet (including Samsung Smart TVs) automatically uses the VPN.
• You can test by visiting whatismyip.com on any device.

Pros & Cons of Router VPN

✅ Protects all devices at once

✅ Great for Smart TVs, game consoles, IoT devices

✅ One login covers your whole household

⚠️ Can slow down speeds if router CPU is weak

⚠️ More complex setup than just installing an app

⚠️ Harder to change server locations (you must log back into the router)
