🇨🇳 Great Firewall · Tested · Updated June 2026
China's Great Firewall (GFW) is the most sophisticated internet censorship system in the world. It uses deep packet inspection (DPI), IP blocking, DNS poisoning, and active probing to detect and kill VPN connections. Most VPNs that work fine in Europe and the US fail completely inside China. This page covers only what actually works in 2026 — tested by users on the ground in Beijing and Shanghai.
Install your VPN BEFORE you land in China. VPN apps are removed from Chinese app stores. ExpressVPN.com and NordVPN.com are blocked inside China. If you arrive without a VPN installed, you cannot easily get one.
Technical background
Understanding the GFW's detection mechanisms explains why only obfuscated protocols survive it — and why standard OpenVPN or WireGuard connections fail within seconds of connecting from inside China.
Technique 1
Deep Packet Inspection (DPI)
The GFW reads packet headers and payload patterns to identify VPN protocols. OpenVPN, WireGuard, and IKEv2 all have distinctive byte sequences in their handshakes that DPI can match against signatures in milliseconds. Standard VPN traffic cannot hide from DPI without an obfuscation layer.
Technique 2
IP Blocking
Known VPN server IP addresses are blacklisted at the router level. VPN providers counter this by rotating IP addresses constantly. The GFW maintains an up-to-date list of known data centre IP ranges and blocks them wholesale — which is why smaller VPNs with limited server infrastructure fail almost immediately.
Technique 3
DNS Poisoning
DNS queries for VPN-related domains are intercepted and return incorrect IP addresses. Querying expressvpn.com or nordvpn.com from inside China returns a blocked or wrong IP. This is why you can't visit VPN websites to download software once you're in-country.
Technique 4
Active Probing
When the GFW suspects a connection might be a VPN, it sends its own probing packets to the suspected server and analyses the response. This is how it catches some obfuscated connections that fool passive DPI — the server's behaviour under probing reveals it as a VPN endpoint.
Technique 5
SNI Inspection
During the TLS handshake, the Server Name Indication (SNI) field reveals the destination hostname in plaintext. The GFW can read this to identify connections to VPN provider infrastructure, even when the payload is encrypted. Encrypted Client Hello (ECH) partially mitigates this, but GFW countermeasures continue to evolve.
The only solution: obfuscated protocols. Obfuscated VPN traffic is engineered to look like ordinary HTTPS traffic — the same protocol used for every website you visit. The GFW cannot block HTTPS without breaking the entire web, so well-implemented obfuscation can survive DPI. Not all obfuscation is equal: ExpressVPN's Lightway with obfuscation and Astrill's StealthVPN are the two implementations that consistently survive the GFW's active probing in 2026.

High
ExpressVPN has the longest track record of any VPN in China. Its proprietary Lightway protocol is built on WireGuard's cryptographic architecture but with an obfuscation layer added on top. When the app detects a high-censorship environment, it automatically routes you through obfuscated servers — you don't need to manually toggle anything.
Most reliable over the past five years from user reports. The GFW does occasionally disrupt ExpressVPN connections — typically during politically sensitive periods like major Communist Party events or national anniversaries — but connectivity usually returns within hours. The 30-day money-back guarantee means that if it doesn't work for your trip, you can get a full refund.

Astrill VPN

China reliability
Very high
Astrill is the most popular VPN among foreigners living long-term in China. Unlike consumer-facing VPNs that treat China as one use case among many, Astrill's StealthVPN and OpenWeb protocols were specifically engineered for the GFW. StealthVPN wraps traffic in an obfuscated SSL layer; OpenWeb mimics standard HTTP and HTTPS browser traffic at the protocol level.
It's more expensive than ExpressVPN at $12.50/month, but expats who depend on VPN access for work — video calls, cloud services, accessing Google — consistently report Astrill as more stable over extended periods than any other provider. The higher price reflects genuine infrastructure investment in China-specific routing.

NordVPN
Obfuscated servers work inconsistently. Good as a backup. Not your primary China VPN.

Inconsistent
NordVPN's obfuscated servers run OpenVPN with an obfuscation layer and can work in China — but results are inconsistent. User reports from 2025–2026 show NordVPN working well during quiet periods and failing more frequently during politically sensitive moments when the GFW's enforcement intensifies. At $3.39/month, it's worth installing as a backup alongside ExpressVPN. Do not rely on it as your only China VPN.
