What is a VPN client on a UniFi Dream Machine

A VPN client on your UDM lets the router itself connect to a VPN server. All devices on your network then route through that VPN tunnel, unless you set up split tunneling.
This is ideal for families with multiple devices or for devices that don’t support native VPN apps.

What you need before you start

A UniFi Dream Machine or UniFi Dream Machine Pro
The UniFi Network Controller up to date
VPN service that supports OpenVPN or WireGuard
VPN server details: server address, port, protocol, and credentials
A backup plan: know how to revert if something goes wrong

Choosing the right VPN protocol

WireGuard: Fast, simple, modern, and typically easier to configure on many devices. If your VPN provider supports WireGuard, you’ll usually get the best speed.
OpenVPN: Very common and well-supported, but may be a bit heavier on CPU usage. Great compatibility across many VPN services.

Important note on firmware and model differences

The steps below are designed for the UniFi Dream Machine UDM and classic UniFi OS environments. If you’re on a newer model or a different OS version, UI labels may vary slightly, but the overall flow stays the same.

Step-by-step guide: Set up a VPN client on the UDM

Prepare your VPN credentials and files

If you’re using OpenVPN: download the .ovpn profile or the necessary certificate/key bundle from your VPN provider.
If you’re using WireGuard: you’ll typically need a public and private key pair and a peers list, or a preconfigured config from your VPN provider.

Access the UniFi Network Controller

Open a web browser and go to your UniFi Network controller URL usually https://. Log in with your admin credentials.

Navigate to Settings

In newer UniFi OS, click on Settings in the left-hand menu.
Then go to VPN, or Networks > VPN the naming can vary slightly by version.

Add a VPN client/network

Choose to create a new VPN Client or VPN Network the exact label may be “Remote Access VPN” or “VPN Client” depending on UI version.
For OpenVPN:
- Choose OpenVPN client mode if available.
- Upload the .ovpn profile or paste the necessary server address, port, protocol, and certificate details as prompted.
For WireGuard:
- Select WireGuard as the VPN type.
- Enter the server endpoint IP:port, and paste your private key. Add the peer’s public key and allowed IPs as instructed by your provider.

Configure routing and overrides

Decide whether you want all traffic to go through the VPN full-tunnel or only specific subnets split-tunnel is often more complex on UDM and might require additional routes.
If you want to route the entire network, enable the option to “Force all traffic through VPN” or equivalent.
If your provider requires DNS changes, set the VPN to use the provider’s DNS or a known safe DNS like 1.1.1.1 or 9.9.9.9 to prevent leaks.

DNS and leaks considerations

To prevent DNS leaks, ensure DNS requests are also sent through the VPN. If your VPN provider offers DNS servers, input them here. Otherwise, adjust the firewall rules to push your VPN DNS and block non-VPN DNS leakage.

Firewall and NAT rules

The UDM usually handles NAT automatically for VPN traffic, but if you’re customizing routes, ensure there’s a firewall rule allowing VPN traffic and enabling NAT for outbound VPN traffic.

Apply and test

Click Save or Apply.
Reboot the UDM if necessary, or just wait for it to apply the new VPN config.
Test the VPN by visiting an IP-check site e.g., whatismyipaddress.com to confirm the IP address corresponds to the VPN exit node.
Check for leaks by testing WebRTC and DNS leaks if available.

Optional: Client-specific VPN routing

If you want to VPN for only specific devices, use VLANs or separate networks, and assign those devices to the VPN-enabled network. This can be a cleaner approach than global VPN on a single UDM if you have a mixed need.

Restore and rollback plan

Create a backup of your current UniFi config before enabling the VPN.
If you run into issues, revert to the previous configuration or disable the VPN from the same VPN settings screen.

Tips to optimize VPN performance on UDM

Choose a VPN server geographically close to your location for lower latency.
If your VPN provider supports WireGuard, prefer it for speed.
Enable “kill switch” or equivalent to prevent traffic leaks if the VPN drops.
Use a wired connection to your main router when testing to avoid wireless interference skewing results.
Check CPU usage on the UDM; VPN processing can be CPU-intensive. If you have many devices or high traffic, consider upgrading to a model with better CPU performance or offloading VPN tasks to a specialized device.
If you experience DNS leaks, switch to VPN-provided DNS or configure DNS over TLS if your provider supports it.

Troubleshooting common issues

VPN won’t connect: Double-check server address, port, and protocol. Verify credentials. Check firewall rules allowing VPN traffic.
Slow speeds: Test different VPN servers. Use WireGuard if available. Check ISP throttling issues. Ensure your VPN provider supports split tunneling if you need local access without VPN.
DNS leaks: Ensure VPN DNS is used. Disable IPv6 if your VPN doesn’t support it properly, and set DNS to a provider’s servers or your VPN’s DNS.
Disconnects: Some VPNs drop due to idle timeouts or server overloading. Try a different server or adjust session settings if your provider offers them.
IoT devices flaky: Some IoT devices don’t handle VPNs well. Consider a separate VPN network for only-critical devices and keep others on a non-VPN network.

Security considerations

Always use a reputable VPN provider with strong encryption AES-256 and modern protocols WireGuard or OpenVPN with strong ciphers.
Enable a kill switch to avoid leaks if the VPN disconnects.
Regularly update UDM firmware to ensure you have the latest security patches.
Consider enablement of dual authentication or strong admin credentials for the UniFi Controller to prevent compromise.

Performance and reliability tips

WireGuard is typically faster and lighter on CPU than OpenVPN, but your provider must support it and your device must handle it efficiently.
If you have a lot of streaming devices, ensure your VPN server supports high-bandwidth connections and avoid congested servers.
Use a wired connection for the primary router to ensure stable VPN throughput.
For households with many connected devices, consider segmenting traffic so non-critical devices don’t all hit the same VPN server.

Advanced topics

Split tunneling on UniFi hardware is sometimes limited; for precise control, you may need to define specific routes and firewall rules. If your use case requires it, setting up a secondary router to handle VPN traffic while your UDM handles local traffic might be a viable approach.
Multi-hop VPN: If your VPN provider offers multi-hop routes, you can configure it as part of your VPN profile if supported. This adds an extra layer of privacy but can reduce speed.
DNS over TLS/HTTPS: Some providers offer DNS over TLS/HTTPS. If supported, enable it to reduce DNS leaks and improve privacy.

Comparing popular VPN providers for UniFi setups
