Starlink VPN Configuration Guide¶
Configure a VPN on Starlink in the UK for privacy, remote access, and bypassing geo-restrictions. This guide covers VPN protocols, router-level and device-level setup, performance impact, and CGNAT considerations for VPN usage.
Understanding VPN Options for Starlink¶
Starlink works with VPN connections but requires consideration of CGNAT, MTU settings, and connection stability. VPN types: Router-level VPN (all traffic routed through VPN - set up on the router for whole-network coverage) and device-level VPN (VPN client on individual devices - simpler but covers only that device). Recommended VPN protocols for Starlink in order of preference: WireGuard (fastest, lowest overhead, recommended for Starlink - 5-10% speed reduction), OpenVPN (widely compatible, 20-30% speed reduction), IKEv2/IPSec (good for mobile devices, 10-15% reduction), and L2TP/IPSec (older protocol, 30-40% speed reduction - avoid). MTU (Maximum Transmission Unit) adjustment is often needed for Starlink VPN connections. Starlink uses PPPoE with MTU 1500. VPN overhead reduces effective MTU. Set your VPN MTU to 1400-1450 for optimal performance. Recommended VPN providers for Starlink UK: Mullvad (WireGuard, £5/month), ProtonVPN (free tier available, £10/month paid), NordVPN (Meshnet for Starlink, £4/month), and ExpressVPN (reliable Starlink performance, £10/month). All support UK exit servers for UK geo-restricted content.
Setting Up VPN on Starlink Step by Step¶
Step 1: Choose VPN provider and protocol. WireGuard is recommended for minimum speed loss on Starlink. Step 2: For router-level VPN: enable Bypass Mode on Starlink and connect a third-party router. The Asus RT-AX86U (£200) supports WireGuard natively. Configure the router VPN client with your provider WireGuard config file. Step 3: For device-level VPN: install the VPN provider app on Windows/Mac/iOS/Android. This is simpler and covers the specific device without affecting other home network traffic. Step 4: Test the connection by checking your public IP address shows the VPN server location. Step 5: Optimise MTU: if experiencing slow VPN speeds, reduce MTU to 1400 on the VPN interface. Step 6: For split tunnelling (some traffic through VPN, some direct), configure the VPN client or router settings. Starlink running VPN typically achieves 80-150 Mbps download depending on protocol and server distance. WireGuard achieves highest speeds. Expect 10-20% additional latency through VPN (total 35-60ms). For bandwidth-intensive activities (streaming, gaming) consider device-level VPN to avoid saturating the Starlink connection with encrypted overhead.
Specifications and Comparison¶
