Yes, Starlink is compatible with VPNs, providing users with additional privacy and the ability to mask their locations. While traditional satellite internet services struggle with VPN connectivity, Starlink’s advanced network design allows VPNs to function effectively. However, Starlink’s network uses Carrier-Grade NAT (CGNAT), which requires VPNs with NAT traversal capabilities to connect reliably.

1. Supported VPN Types: Starlink generally supports VPNs that use TCP or UDP protocols, such as those based on OpenVPN and IKEv2/IPsec. SSL-based VPNs (which rely on SSL/TLS encryption for security) often work best with Starlink because SSL/TLS protocols are well-suited for traversing Starlink’s Carrier-Grade NAT (CGNAT). Common SSL-based protocols include:
   • OpenVPN: Operates over both TCP and UDP and uses SSL/TLS encryption.
   • SSTP (Secure Socket Tunneling Protocol): Uses SSL/TLS and is primarily supported on Windows.
   • Proprietary Protocols: Some VPNs offer custom SSL-based protocols, such as NordLynx (based on WireGuard), ExpressVPN’s Lightway, and Hotspot Shield’s Catapult Hydra, which are optimized for modern networks.
2. NAT Traversal: Starlink’s network uses CGNAT, meaning that multiple users share the same public IP address. VPNs that support NAT traversal (like OpenVPN over TCP or proprietary SSL-based protocols) are typically more reliable on Starlink.
3. Performance Impact: While VPNs work on Starlink, they may add latency or reduce speeds due to the nature of satellite internet and the additional encryption overhead. SSL-based protocols tend to perform well because they are designed to handle complex network environments with better resilience.
4. App Compatibility: Note that the Starlink app itself may not work properly when a VPN is active. Starlink does not offer direct support for troubleshooting VPN issues, so users are encouraged to contact their VPN provider for assistance.

How Does VPN Passthrough Work with Starlink?

Starlink routers come equipped with VPN passthrough functionality, which allows VPN traffic to “pass through” Starlink’s network without interference. This is essential because VPNs often use SSL/TLS protocols for security, which must navigate Starlink’s CGNAT setup. CGNAT assigns multiple users to a shared public IP address, making traditional VPN gateway setups challenging. Passthrough is vital for compatibility, especially with older protocols like PPTP, L2TP, and IPsec.

Limitations of Standard vs. Business/Mobile Starlink Plans for VPNs

Starlink offers various plans, but only the Business and Mobile plans allow users to install a VPN directly on the router, thanks to their public IP configuration. With Standard plans, users are assigned private IPs, so a VPN must be set up directly on the device, as router-level VPN setup isn’t feasible.

Benefits of Using a VPN with Starlink

• Enhanced Security: VPNs add an extra encryption layer to protect your data from potential hackers and other threats, supplementing Starlink’s basic security features.
• Improved Privacy: VPNs help prevent tracking by hiding your online activity and encrypting your traffic. While CGNAT complicates individual tracking, your internet service provider can still log certain activities. A VPN encrypts your traffic, ensuring it remains private.
• IP Flexibility and Location Spoofing: Using a VPN allows access geo-blocked content and bypass IP restrictions. Some websites block CGNAT-assigned IPs, but a VPN can provide a new IP address that isn’t flagged, providing seamless access.

Downsides of Using a VPN with Starlink

• Speed and Latency Impact: VPNs can increase latency and slightly reduce speeds due to encryption and routing. This is especially true with satellite internet, where data already travels long distances.
• Compatibility Limitations: Starlink’s app may not work correctly while a VPN is active. For troubleshooting, temporarily disable the VPN.

Common VPN Connectivity Issues with Starlink and Solutions

• Connection Failures:
  • Solutions: Ensure a stable network connection, try a different server location, restart your device, adjust VPN settings, or use the “bypass mode” on an external router if available.
• Frequent VPN Disconnections:
  • Cause: Satellite handoff between Starlink satellites may cause brief interruptions that disconnect VPNs.
  • Solution: Use mobile-friendly protocols like IKEv2/IPsec, which are designed to quickly re-establish connections during network switches.
• Reduced VPN Speed:
  • Solutions: Connect to a VPN server close to your physical location, and use high-speed protocols like WireGuard or proprietary options like NordLynx.
• High Latency:
  • Solutions: Choose servers close to your location and avoid congested servers to reduce latency.

Best VPN Protocols for Optimizing Starlink VPN Usage

• OpenVPN (TCP/UDP): Known for reliability and security, OpenVPN is ideal for general use, with TCP for stability and UDP for faster performance.
• WireGuard: This protocol is efficient and fast, making it well-suited for streaming and gaming.
• IKEv2/IPsec: Common in mobile networking, IKEv2/IPsec is resilient against disconnections, a common issue with satellite connections.
• Proprietary Protocols: Some VPNs, like NordLynx (NordVPN) and Lightway (ExpressVPN), offer high-speed, reliable protocols optimized for modern network setups, including satellite connections.
