ASUS Guest WiFi With or Without VPN: Setup Guide

· ·

On supported ASUS routers, you can create a separate WiFi network (SSID) that routes connected devices through a VPN profile, while another network uses the regular ISP connection. This is useful for streaming TVs, guests, work devices, and family members who need different VPN behavior.

The available controls depend on your ASUS model and firmware. Newer routers may call the feature Guest Network Pro or simply Network; older routers may only have Guest Network, which does not offer the same VPN-by-SSID options.

What You Need Before Starting

  1. Connect to your ASUS router and open http://www.asusrouter.com or its LAN IP. For login details, see AsusWRT Router Access Guide.
  2. For a VPN WiFi network, first set up and verify at least one connected VPN profile under VPN > VPN Fusion. Choose a supported VPN provider from the AsusWRT VPN Setup Guides, then review How to Use ASUS VPN Fusion: Assign Devices and Multiple VPNs for routing options.
  3. Look for Guest Network Pro, Network, or VPN Network in your ASUS firmware. If you only see the traditional Guest Network screen, read the legacy note below before proceeding.

Create a Dedicated WiFi Network That Uses the VPN

Preferred route for supported ASUS models: create a VPN Network SSID so all devices joining that SSID use the chosen VPN without individual device assignments.

  1. Open Guest Network Pro > VPN Network, or the equivalent Network > Add Network > VPN Network menu in newer firmware.
  2. Choose a recognizable WiFi name such as Home-VPN and a strong WiFi password.
  3. Select the configured, connected VPN Fusion client/profile and enable VPN routing for that network.
  4. Review any options for local-network access, guest isolation, and bands, then click Apply.
  5. Connect a test device to the new Home-VPN WiFi SSID and check its public IP.

ASUS official walkthrough: Guest Network Pro / VPN Network Setup.

Alternative: Assign a VPN to an Existing Guest Network Pro SSID

  1. In Guest Network Pro / Network, open the existing Guest Network profile.
  2. Select the VPN tab, enable VPN routing, and choose your existing VPN Fusion client.
  3. Click Apply, reconnect a device to the guest SSID, and verify the VPN IP.

ASUS also documents this path: Assign a VPN to Guest Network Pro.

Create a Separate WiFi Network Without a VPN

Use a guest/secondary network routed through the regular ISP internet connection for devices that should not use the VPN.

  1. Under Guest Network Pro / Network, add a normal Guest Network or other suitable network profile (not the VPN Network preset).
  2. Set a clear name such as Home-ISP and secure it with a strong password.
  3. In that network profile’s VPN tab, leave the VPN assignment disabled or choose the Internet/ISP path if your firmware offers it.
  4. Check your VPN Fusion default connection and device policies. If a VPN is set to Apply to all devices, simply turning off the Guest Network’s VPN toggle may not guarantee an ISP bypass on every firmware. Configure an explicit ISP/bypass route where supported.
  5. Save, join the Home-ISP network with a test device, and confirm the public IP matches the ISP connection.

Confirm Each WiFi Network Uses the Intended Internet Route

  1. Connect a phone or laptop to the VPN WiFi SSID. Disable any VPN app or iCloud Private Relay on the device for this test.
  2. Visit WhatIsMyIPAddress.com and note the public IP and location. This should reflect your selected VPN endpoint.
  3. Disconnect and join the ISP WiFi SSID. Repeat the IP check; it should now show the ISP’s public internet route.
  4. If both SSIDs show the same IP, review the VPN Fusion default profile, guest-network VPN assignment, and any device-specific rules.

Common Issues and What to Check

I only see “Guest Network,” not “Guest Network Pro” or “VPN Network”

Your router may use older firmware or lack this feature. Traditional Guest Network creates a separate WiFi SSID, but the VPN routing option may not exist. Use VPN Fusion device assignments as an alternative rather than assuming the guest network automatically bypasses or uses the VPN.

Every network still uses the VPN

Check whether Apply to all devices is enabled in VPN Fusion. If it is, verify that the guest profile actually overrides the default route on your firmware. You may need an explicit per-network or per-device ISP rule.

A phone reports the wrong IP although the guest VPN profile is correct

Temporarily disable device-level VPN apps, iCloud Private Relay / Limit IP Address Tracking, browser proxy, or Private DNS settings, then reconnect. See Device Settings That Interfere With Router VPN.

Guest devices cannot reach local printers or other LAN devices

Check the guest network’s intranet access / network isolation settings. Changing isolation affects LAN access, not necessarily VPN selection. Keep guests isolated unless LAN access is actually needed.

How to Use ASUS VPN Fusion: Assign Devices and Multiple VPNs

· ·

ASUS VPN Fusion lets supported AsusWRT routers run VPN client profiles and decide which connected devices use each VPN connection. You can send the entire network through one VPN, use separate VPN profiles for selected devices, or leave certain devices on the regular ISP connection.

This guide covers how to use ASUS VPN Fusion to assign devices to specific VPN connections, manage multiple VPN profiles simultaneously, and choose which devices use a VPN or connect directly through your ISP. These features work with supported VPN providers and protocols, including WireGuard and OpenVPN.

Open VPN Fusion

  1. Connect your computer or phone to your ASUS FlashRouter’s WiFi or LAN.
  2. Open http://www.asusrouter.com or the router’s LAN IP (often 192.168.50.1) and log in. See How to Access Your AsusWRT FlashRouter Settings.
  3. Go to VPN > VPN Fusion. Add and configure at least one working VPN client profile before assigning devices.
ASUS VPN Fusion page with Add Profile and Internet Connection
VPN Fusion displays your saved VPN profiles and the Add Profile option.

Method 1: Apply One VPN to All Devices

Use this option when you want the selected VPN profile to be your router’s default connection.

  1. In VPN Fusion, open the VPN profile that should provide the default internet route.
  2. Enable Apply to all devices (or Default Connection in firmware that uses that label).
  3. Click Apply all settings, then enable the VPN profile.
  4. Connect a test device to the router and check its IP. If you use per-device overrides, verify those rules separately.
ASUS VPN Fusion Apply to all devices setting and device count
Enable Apply to all devices to use the selected VPN as the default connection.

Method 2: Send Only Selected Devices Through a VPN

  1. In VPN Fusion, turn off Apply to all devices for a profile when you do not want that VPN used network-wide.
  2. Open the profile’s Device area using the pencil/edit icon or the firmware’s device-assignment control.
  3. Select the intended devices (for example, a TV and streaming box), confirm with OK, then click Apply all settings.
  4. Enable the VPN profile and verify the selected devices’ public IPs.
  5. For devices that should use the normal ISP internet, leave them on the Internet Connection route or explicitly set the Internet/bypass rule available in your firmware. Remove any conflicting VPN assignments.

Important: A device being connected to ASUS WiFi does not guarantee that it is assigned to the desired VPN. Check the assigned profile and the actual public IP.

How Multiple VPN Connections Work

On supported models, VPN Fusion can keep several VPN connections active and route different devices through different providers at the same time. For example:

TVNordVPN — WireGuard
LaptopProton VPN — OpenVPN
Streaming deviceSurfshark — OpenVPN
Work computerRegular ISP connection

You may be able to run one WireGuard profile and multiple OpenVPN profiles concurrently, but connection limits and supported combinations vary by ASUS router model and firmware. Adding many saved OpenVPN profiles is not the same as having all of them connected at once.

  1. Create separate profiles with clear names, such as Nord-US-WG, Proton-US-OVPN, and Surfshark-UK-OVPN.
  2. Enable only the profiles you need and confirm each shows connected.
  3. Assign each client device to the appropriate active profile; avoid applying conflicting default routes.
  4. Verify each device’s observed IP and server country. If one tunnel fails, test it individually with the other profiles temporarily disabled.

ASUS reference: How VPN Fusion handles multiple tunnels and devices.

Confirm a Device Is Actually Using the VPN

  1. In VPN Fusion, confirm the target profile’s connection status is active.
  2. Check the device’s assignment in the ASUS VPN Fusion interface.
  3. On that same device, visit IPLeak.net or another public-IP checker.
  4. Compare the reported public IP and location with the VPN server assigned to that device.
  5. If the device still shows your ISP IP, test with its own VPN app and iCloud Private Relay / Private DNS / browser proxy disabled. Use Device Settings That Can Interfere With Your Router VPN.

Quick isolation test

  1. Turn off VPN Fusion routing for a test device and confirm ISP internet works.
  2. Turn on just one known-working VPN profile for that device.
  3. Recheck public IP. If it now works, reintroduce other profiles/assignments individually.

Want a Separate WiFi Network With or Without VPN?

Rather than selecting devices one at a time, supported ASUS routers offer Guest Network Pro or Network > VPN Network features that can associate a WiFi SSID with VPN routing. See ASUS Guest WiFi With or Without VPN: Setup Guide.

On routers with only the traditional Guest Network feature, available VPN-by-SSID behavior may differ; do not assume the standard guest SSID bypasses a network-wide VPN default.

NordVPN Setup for AsusWRT: Token, WireGuard & OpenVPN

· ·

Set up NordVPN on an ASUS router using AsusWRT VPN Fusion. Supported ASUS firmware offers three different VPN types: NordVPN (access-token integration), WireGuard (downloadable .conf file), and OpenVPN (manual service credentials plus an .ovpn file). Choose the method that matches your needs and your router’s available options.

All configuration is completed directly through your ASUS router’s administration interface using VPN Fusion. Before starting, make sure your router is connected to the internet, your firmware supports VPN Fusion, and you have an active NordVPN subscription.

Which NordVPN Option Should You Choose?

1. NordVPN

NordVPN access token and a country/region dropdown. The built-in ASUS/NordVPN integration is the simplest approach if you only need a country, not an exact server file.

Follow token setup →

2. WireGuard

Import a NordVPN .conf configuration file for a server selected in Nord Account. Useful when you want a downloaded profile for a particular server.

Follow WireGuard setup →

3. OpenVPN

Import a NordVPN .ovpn server file and enter your separate manual service username and password. Also used for NordVPN Dedicated IP.

Follow OpenVPN setup →

Option 1: NordVPN Dropdown — Token-Based NordLynx

Select the NordVPN type inside VPN Fusion. This is the integrated token-based setup and offers a country/region selection, rather than a manually imported server file.

  1. In Nord Account, open NordVPN Access Tokens and complete email/account verification if requested.
  2. Generate an access token, choose an expiry period if NordVPN offers that setting, and copy the token immediately (it may only be displayed once).
  3. On your ASUS router, open VPN > VPN Fusion > Add profile.
  4. Set VPN Type to NordVPN. Name the profile, select your preferred Region, and paste the token.
  5. Choose Apply to all devices if you want it as the default route, or assign only selected devices (see the VPN Fusion guide below).
  6. Click Apply and Enable / Apply all settings, as shown in your firmware, and verify the profile connects.
ASUS VPN Fusion NordVPN VPN type with Region and Token fields
Keep: existing ASUS NordVPN region/token form (remove any private token before publishing).

Need a specific server? Use the separate WireGuard file method below or the OpenVPN configuration-file method. Do not expect the token-based country dropdown to accept a .conf or .ovpn file.

Option 2: WireGuard Dropdown — Import a NordVPN .conf File

NordVPN now provides downloadable WireGuard configuration files through its manual server recommendation page. This is different from the built-in NordVPN token option in VPN Fusion.

  1. Sign in to Nord Account and open NordVPN Server Recommendation.
  2. Choose your preferred country and server; use the available filters if you need to narrow the list. Select a currently available server.
  3. Choose Get setup configuration, select WireGuard from the protocol menu, and click Download config. Save the downloaded .conf file.
  4. In your ASUS router settings open VPN > VPN Fusion > Add profile, then set VPN Type to WireGuard (not NordVPN).
  5. Use the ASUS Import configuration / file-import control to select the NordVPN .conf file. Confirm the imported parameters and save the profile.
  6. Choose the target devices or enable the default/all-devices route. Click Apply and Enable, then check the VPN status and your public IP.


NordVPN’s official instructions: How to download WireGuard and OpenVPN configuration files.

Option 3: OpenVPN Dropdown — Credentials + .ovpn File

OpenVPN requires two separate items: the configuration file for your desired server and NordVPN’s manual service credentials. Your normal Nord Account email/password is not the correct credential pair for this method.

  1. Open NordVPN Manual Service Credentials and copy the service username and service password after any required verification.
  2. Open NordVPN OpenVPN Configuration Files and choose a server/location. Download its UDP .ovpn file, or TCP .ovpn if UDP does not work on your network.
  3. On ASUS, go to VPN > VPN Fusion > Add profile and set VPN Type to OpenVPN.
  4. Enter a connection name, Import .ovpn file, and paste the NordVPN manual service username and password in the corresponding fields.
  5. Choose devices or Apply to all devices, then click Apply and Enable. Confirm VPN Fusion shows a successful connection.

Keep: existing ASUS OpenVPN profile form. New screenshots should use a larger clean capture if available.

Server selection: The location is controlled by the server named in the imported .ovpn file. To switch locations, import another server file or use a separate OpenVPN profile.

NordVPN Dedicated IP — OpenVPN Only

If you have purchased and activated the NordVPN Dedicated IP add-on, use your specific Dedicated IP OpenVPN configuration file. Do not select the ordinary NordVPN token integration or a regular shared server.

  1. In your Nord Account, open the Dedicated IP details and download the assigned server’s OpenVPN UDP or TCP configuration file, following NordVPN Dedicated IP manual configuration instructions.
  2. Open NordVPN Manual Service Credentials and copy the manual username and password.
  3. In ASUS VPN Fusion > Add profile, choose OpenVPN.
  4. Import the Dedicated IP .ovpn file, enter manual service credentials, save, enable, and verify the public IP matches your assigned Dedicated IP.

Assign Devices, Verify the VPN, and Troubleshoot

One VPN for everyone, or different VPNs for different devices?

VPN Fusion lets you use a VPN profile as the default connection for all devices or assign specific client devices to different profiles. Some supported ASUS models can maintain one WireGuard tunnel alongside multiple OpenVPN profiles, but the number of simultaneous tunnels is model/firmware dependent; creating multiple profiles does not mean all can be active simultaneously.

For step-by-step device assignments, default routing, profile conflicts, and bypassing the VPN, see How to Use ASUS VPN Fusion and Assign Devices to VPN Profiles. For a dedicated WiFi network with VPN or ISP routing, see ASUS Guest Network VPN / No-VPN Setup.

Verify the IP of the actual device

  1. Confirm your chosen profile shows Connected in VPN Fusion.
  2. Join the ASUS WiFi or LAN using a device that is actually assigned to that VPN profile.
  3. Open NordVPN IP Address Check and compare the public IP/location with the intended server or Dedicated IP.
  4. If the device shows an ISP IP, first check Apply to all devices and the per-device assignments in VPN Fusion.
  5. Disconnect a NordVPN app, Apple iCloud Private Relay, browser VPN/proxy, or other device-level network service during testing. Follow Router VPN Shows Wrong IP? Check Device Settings.

If VPN Fusion will not connect

  1. Temporarily disable the failing profile and confirm the ASUS router works using its normal ISP internet connection.
  2. For NordVPN type, check that the access token is valid and hasn’t expired; regenerate if needed.
  3. For WireGuard, import a fresh .conf from the Nord server recommendation page and make sure the profile is enabled.
  4. For OpenVPN, double-check manual service credentials (not website credentials) and try a different server file or TCP instead of UDP.
  5. Check that device-assignment rules point to the intended active profile, then retest with one clean device.
