Yes. Starlink supports VPNs that use TCP or UDP. SSL based VPNs typically work best to traverse CGNAT. NAT traversal support is required by the VPN.

Using a VPN can sometimes affect your internet performance. When you use a VPN, your data is often encrypted and then sent through different servers before reaching the internet. These extra steps can increase the time it takes for your data to travel back and forth, which might affect your internet performance.

We can help ensure your Starlink connection is working as expected, but please note that we cannot troubleshoot VPN connection issues, as they fall outside the scope of our network support. Additionally, the Starlink app might not function properly when a VPN is in use. Below is an overview of expected compatibility status for various VPN protocols in CGNAT and Public IP environments:

Client to Site VPN Protocols that generally work well with CGNAT:

• SSTP (SSL/TLS/DTSL)
• OpenVPN
• WireGuard

Client to Site VPN Protocols that generally do not work well with CGNAT:

• PPTP
• L2TP

Site to Site VPN Protocols that generally work well with CGNAT:

• MPLS
• IKEv2/IPsec
• OpenVPN

Site to Site VPN Protocols that generally do not work well with CGNAT:

• GRE
• IPsec (without NAT-T)
• L2TP

If your VPN is incompatible with CGNAT, switching to a Public IP may help. However, Public IPs are only available with select service plans. This list of plans is not exhaustive and does not guarantee VPN compatibility. Because VPN configurations vary, Starlink cannot guarantee compatibility even with a Public IP.

If you're experiencing issues with a VPN while using Starlink, please contact your VPN provider for assistance.
