Ipsec vpn with starlink

It looks like you’re trying to figure out how to get IPsec VPN working with Starlink, and it’s a common question that comes with a few twists and turns! While setting up a VPN with Starlink is definitely possible, especially for securing your own devices, getting IPsec site-to-site VPNs or hosting your own VPN server can be a bit more of a puzzle.

At its core, Starlink’s default service uses something called Carrier-Grade Network Address Translation CGNAT. Think of CGNAT as a big apartment building where many residents Starlink users share a single public mailbox IP address to send and receive mail from the outside world. This is great for conserving IPv4 addresses, but it means you don’t get your own unique, publicly accessible IP address by default. This lack of a dedicated public IP address makes it challenging for external devices to initiate connections to your Starlink network, which is often crucial for traditional IPsec VPN setups.

The good news is, if you’re just looking to secure your internet traffic by connecting out to a VPN service like for privacy or accessing geo-restricted content, Starlink works pretty seamlessly with most major VPN providers. Many Starlink users successfully use services like NordVPN for this very purpose. They even have a “VPN passthrough” feature built into their routers to help this traffic flow smoothly. If you’re looking for a reliable VPN that works great with Starlink for personal use, I’ve had excellent experiences with NordVPN, and you can check them out right here: .

However, if your goal is more complex, like setting up a site-to-site IPsec VPN to connect two offices, or hosting a VPN server at your Starlink location that others can connect to, then you’re going to need some workarounds. Starlink’s Business plans offer a public IP address option, which definitely helps, but even then, it’s usually dynamic, not truly static.

So, while Starlink is a must for internet access in remote areas, understanding its networking specifics is key to making IPsec VPNs work the way you want. Let’s dig into the details.

Understanding Starlink’s Network: The CGNAT Conundrum

When you get Starlink for your home, you’re usually on their “Standard” or “Residential” plan. With these plans, Starlink uses what’s called Carrier-Grade Network Address Translation CGNAT. I know, that’s a mouthful, but let me break it down.

Imagine your home network has a private IP address, like 192.168.1.100. Your router then translates that private IP into a single public IP address that the rest of the internet sees. That’s regular NAT. Now, with CGNAT, Starlink takes it a step further. Multiple Starlink customers share one public IP address. So, your Starlink router gets a private IP address often in the 100.64.0.0/10 range, which then goes through another layer of NAT before hitting the public internet with a shared IP.

Why CGNAT is a Big Deal for IPsec VPNs

This CGNAT setup has some significant implications, especially for hosting services or setting up specific types of VPNs:

• No Inbound Connections by Default: The biggest challenge is that CGNAT effectively blocks all inbound ports and prevents external devices from initiating connections to your Starlink network. This is a fundamental hurdle for traditional IPsec VPNs where a remote site or client needs to connect to a VPN server at your Starlink location.
• Port Forwarding is Out: Because of the shared IP address and the extra layer of NAT, you generally can’t set up traditional port forwarding with Starlink’s standard service. This means you can’t tell the internet to send specific types of traffic like VPN connection requests directly to a device on your home network.
• Dynamic IP Addresses: Even if you manage to get a routable IP like with Starlink Business plans, it’s often dynamic, meaning it can change. For IPsec, a changing public IP address can break your VPN tunnel unless you use a Dynamic DNS DDNS service, which can add another layer of complexity.

Starlink does provide a public IPv6 /56 prefix to all customers, and IPv6 is “native” to their network. If your devices and the other end of your VPN support IPv6, this could offer a path around some IPv4 CGNAT limitations. However, many traditional IPsec VPN setups still heavily rely on IPv4.

Can You Use a VPN Client with Starlink? Yes, Easily!

Let’s clarify something right away: if you just want to use a VPN to encrypt your internet traffic, hide your IP address, or bypass geo-restrictions, then yes, you absolutely can use a VPN client with Starlink, and it’s generally pretty straightforward. This is about connecting out from your Starlink network to a commercial VPN provider’s server.

Starlink’s routers are designed to work well with VPN services and feature a “VPN passthrough” function. This means your VPN client software on your devices like your laptop, phone, or tablet can “tunnel” its encrypted traffic through the Starlink router to the VPN server without issues.

How to Set Up a VPN Client with Starlink The Easy Way

Setting up a VPN client with Starlink is almost identical to setting it up with any other internet service:

1. Choose a Reputable VPN Service: This is the most important step. Look for a VPN known for speed, strong encryption, a no-logs policy, and a wide network of servers. Some popular choices that work well with Starlink include NordVPN, ExpressVPN, Surfshark, and CyberGhost.
2. Download and Install the VPN App: Once you’ve chosen a provider, download their app for your specific device Windows, macOS, iOS, Android, etc..
3. Log In and Connect: Open the app, log in with your credentials, and select a server location. Many apps offer a “Quick Connect” option to automatically pick the fastest server for you. Hit connect, and you’re good to go!

This approach secures individual devices. If you want all devices on your network to be protected by a VPN, you’d typically set up the VPN on a compatible router. However, the standard Starlink router doesn’t support direct VPN installation. You’d need a third-party, VPN-compatible router like a custom router running pfSense, OpenWRT, or specific models from UniFi, Asus, etc. connected to your Starlink system. For this, you’ll want to enable “Bypass Mode” on your Starlink router to let your third-party router handle everything.

Site-to-Site IPsec VPN with Starlink: The Real Challenge and How to Tackle It

Now, this is where things get a bit more involved. Setting up a site-to-site IPsec VPN means you want to create a secure tunnel between two distinct networks e.g., your remote Starlink office and your main headquarters so they can communicate as if they were on the same local network. Because of Starlink’s default CGNAT, this isn’t as simple as punching in an IP address and a pre-shared key.

Traditional IPsec VPNs often expect both ends of the tunnel to have publicly routable IP addresses, where one side can initiate the connection to the other. With CGNAT on the Starlink end, your remote office can’t directly receive incoming connection requests.

However, it’s not impossible! Here are the main strategies and workarounds: VPN at SDSU: Staying Secure and Connected on Campus and Beyond

1. Starlink Business Priority Plan with Public IP Option

If you’re using Starlink for a business, upgrading to a Starlink Business Priority plan can significantly simplify things. These plans offer an option for a public IPv4 address.

• Public, but Dynamic: While these IPs are publicly routable meaning inbound connections are possible, they are still dynamically assigned and can change, especially if you move your Starlink dish or after software updates. This means you’ll definitely need a Dynamic DNS DDNS service at your Starlink site. The DDNS client on your router will update a hostname like “myremoteoffice.ddns.net” with your current public IP, so the other end of your VPN always knows where to connect.
• Cost Consideration: Starlink Business plans come with a higher monthly cost typically $250+/month.
• Configuration: Even with a public IP, you’ll still need a third-party router like a Fortigate, UniFi Security Gateway/UDM, Mikrotik, or a custom build with pfSense that can initiate and maintain an IPsec tunnel. You’ll put your Starlink router in “Bypass Mode” and connect your VPN-capable router directly.

Many users on forums have successfully implemented IPsec site-to-site VPNs with Starlink Business plans, usually with one side the main office with a static public IP acting as the “hub” and the Starlink site with its dynamic public IP and DDNS acting as the “spoke” that initiates the connection.

Important Protocols for Site-to-Site VPNs with CGNAT:
Starlink’s official help pages mention that for site-to-site VPNs with CGNAT, protocols like IKEv2/IPsec and OpenVPN generally work well, especially with NAT traversal NAT-T support. Older protocols like GRE and IPsec without NAT-T are often dropped.

2. Cloud-Based VPN Server / VPS Relay

This is a popular and often more reliable solution for residential Starlink users who don’t have the public IP option. The idea is to use a third-party cloud server a Virtual Private Server, or VPS as a relay point.

Here’s how it generally works: Prostavive ke fayde in hindi

• The Cloud Acts as the Hub: You set up a VPN server e.g., OpenVPN, WireGuard, or even an IPsec server if configured carefully on a VPS in a data center that does have a static public IP address.
• Starlink Connects Out: Your router at the Starlink location acts as a VPN client, initiating an outbound connection to your cloud VPN server. Because it’s an outbound connection, CGNAT isn’t an issue.
• Main Office Connects In: Your main office or other remote clients also connects to the cloud VPN server.
• Traffic Relayed: All traffic between your Starlink site and your main office is then routed through this central cloud VPN server.

This creates a “hub-and-spoke” topology where the cloud VPS is the hub, and both your Starlink site and main office are spokes. Tools like Tailscale, which create overlay networks, also leverage similar concepts to establish connections even behind CGNAT.

3. Client-Initiated Tunnels e.g., Reverse Tunnels

This is a variation where the Starlink side of the connection always initiates the tunnel. Instead of the remote side trying to connect to Starlink, the Starlink side connects out to a VPN endpoint that has a public IP which could be your main office if it has a static IP, or a cloud VPS. This is crucial because Starlink’s CGNAT blocks incoming connections, but outbound connections are fine.

If your VPN appliance at the Starlink site e.g., a Fortigate or UniFi device can act as a VPN client and initiate an IPsec tunnel to a public IP at your main office, this can work. The challenge here is if the public IP at your Starlink site changes, the tunnel will need to re-establish, and if the remote side needs to initiate, it still won’t work without a public IP on the Starlink end. Using IKEv2/IPsec, which is known for its resiliency and ability to quickly re-establish connections, can be helpful here.

4. IPv6 for Direct Connections Future Potential

Starlink is an IPv6-native network and allocates a /56 IPv6 prefix to customers. This means that devices on your Starlink network can get publicly routable IPv6 addresses. If both ends of your site-to-site VPN are IPv6-capable, and your main office also has a public IPv6 address, you could potentially set up an IPsec VPN directly using IPv6, bypassing IPv4 CGNAT altogether.

However, implementing this requires that all your networking equipment and the services you need to access are fully IPv6 compatible, which isn’t always the case yet. Also, Starlink’s current router doesn’t offer IPv6 firewall configuration, so you’d need a third-party router to implement proper security for your IPv6 direct connections.

Specific Hardware Considerations

If you’re delving into site-to-site VPNs with Starlink, you’ll almost certainly need a third-party router. The stock Starlink router is pretty basic and doesn’t offer the granular control needed for complex VPN configurations.

• UniFi Ubiquiti: Many users successfully configure UniFi Security Gateways USG or UniFi Dream Machines UDM for site-to-site VPNs with Starlink. They often use a “hub-and-spoke” IPsec setup where the Starlink end initiates the connection to a fixed public IP on the other side. You’ll need to enable “Bypass Mode” on the Starlink router and connect the UniFi device directly.
• Fortigate: Fortigate firewalls are also commonly used. Users report that with a Starlink Business public IP, IPsec tunnels can be established. However, performance issues significant speed drops have been observed, possibly due to encryption overhead or how Starlink handles packet loss with VPN traffic. Switching Fortigate policies from Proxy to Flow-based has reportedly helped some users achieve better speeds.
• Mikrotik: Like Fortigate, Mikrotik routers can be configured for IPsec VPNs with Starlink, especially when a public IP is available on the Starlink Business plan.
• pfSense/OpenWRT: These open-source router operating systems offer incredible flexibility and are excellent choices for building a custom VPN solution, allowing you to configure almost any VPN protocol and setting imaginable.

Performance Considerations

When you throw a VPN into the mix with Starlink, you might notice some changes in your internet performance.

• Increased Latency: VPNs add an extra step to your internet traffic encryption, sending to a VPN server, decryption. This inevitably adds a bit of latency. While Starlink itself has much lower latency than traditional satellite internet typically 20-50ms, a VPN can bump that up further.
• Reduced Speed: The encryption and decryption process, plus the extra routing, can also lead to a decrease in raw internet speed. The extent of this depends heavily on your VPN provider, the protocol you choose WireGuard is often faster than IPsec for general client use, and the load on the VPN server you connect to. Some users have reported significant speed drops with IPsec over Starlink, especially for site-to-site connections. Adjusting MTU Maximum Transmission Unit settings and encryption protocols can sometimes help mitigate these issues.
• Satellite Hand-offs: Starlink’s low Earth orbit satellites are constantly moving, meaning your dish regularly switches between them. This can sometimes cause momentary disconnects, which might lead to VPN connection drops. Using a VPN protocol like IKEv2/IPsec for client-to-site is resilient and can quickly re-establish connections in these situations.

Best Practices for VPNs with Starlink

• Use a Reputable VPN Provider for client-to-site: For general internet privacy and access, stick to well-known VPNs like NordVPN. They optimize their networks for speed and stability, which is crucial with satellite internet.
• Enable Bypass Mode for third-party routers: If you’re using your own VPN-capable router, make sure to enable “Bypass Mode” on your Starlink router via the Starlink app. This lets your custom router handle all networking functions.
• Consider Protocols: For client-to-site VPNs, WireGuard and OpenVPN TCP or UDP are generally recommended for their balance of speed and security with Starlink. For site-to-site, IKEv2/IPsec with NAT-T or OpenVPN are often the most compatible, especially when dealing with CGNAT.
• Dynamic DNS DDNS for Public IPs: If you have a Starlink Business plan with a public IP, always use a DDNS service so your remote VPN endpoint can find your Starlink location even if the IP changes.
• Monitor and Test: Keep an eye on your speeds and latency, especially after setting up a VPN. Run speed tests with and without the VPN to understand the impact.
• Troubleshoot Systematically: If you face issues, check your internet connection first. Try different VPN server locations or protocols. Sometimes, a simple restart of devices can help.

Setting up IPsec VPN with Starlink, particularly for site-to-site connections, requires a bit more technical know-how than a simple client-to-server connection. But with the right understanding of Starlink’s network, the right equipment, and a good strategy, you can absolutely make it work!

Frequently Asked Questions

What is CGNAT and how does it affect VPNs on Starlink?

CGNAT Carrier-Grade Network Address Translation is when multiple Starlink users share a single public IP address. This primarily affects VPNs by preventing inbound connections to your Starlink network, meaning you can’t easily host a VPN server or set up traditional site-to-site tunnels where the remote side initiates the connection.

Can I install a VPN directly on my Starlink router?

No, the standard Starlink router does not support direct VPN installation or configuration. To use a VPN at the router level for your entire network, you’ll need to use a third-party, VPN-compatible router and enable “Bypass Mode” on your Starlink router.

Will using a VPN with Starlink slow down my internet speed?

Yes, using a VPN can potentially increase latency and decrease your internet speed with Starlink. This is because your data is encrypted and routed through an extra server. The impact varies depending on the VPN provider, the protocol used WireGuard is often faster, and the distance to the VPN server. The Rise of AI Voices in Documentaries

How can I get a static IP address with Starlink for my VPN?

Starlink does not offer truly static IP addresses for any plan. However, Starlink Business Priority plans offer a public IPv4 address option, which is dynamically assigned but generally stable for a location. For residential users, alternatives include using a VPN provider with a dedicated IP option or tunneling through a cloud-based Virtual Private Server VPS.

What is “VPN passthrough” on Starlink?

VPN passthrough is a feature on Starlink routers that allows encrypted VPN client traffic to “tunnel” through the router to a VPN server outside your network. It essentially ensures that your device-level VPN connections aren’t blocked by the router’s defenses, making it easy to use commercial VPN services.

Can I use IPsec to create a site-to-site VPN with a regular Starlink residential plan?

It’s very challenging to set up a traditional IPsec site-to-site VPN with a standard Starlink residential plan due to CGNAT blocking inbound connections. Workarounds typically involve using a Starlink Business plan with its public IP option, a cloud-based VPN relay VPS, or a client-initiated tunnel where the Starlink side always connects out to a public IP endpoint.

Which VPN protocols work best with Starlink?

For client-to-site connections, OpenVPN especially over UDP and WireGuard are generally recommended for their performance and compatibility with Starlink’s CGNAT environment. For site-to-site VPNs, IKEv2/IPsec with NAT-T and OpenVPN are often the best choices when dealing with CGNAT, as they are designed to traverse NAT layers.
