Half of what's published online about Kill Switch is recycled from 2019. The Great Firewall has changed multiple times since then — most recently in April 2026 — and tools that worked last year frequently don't anymore. Below is the current, tested setup as of 2026-04-04.
Why Kill Switch Is Specifically Hard from China
China's Great Firewall (GFW) is the most sophisticated state-level censorship system on the planet. It combines DNS poisoning, TLS fingerprinting, IP blocking and deep packet inspection (DPI) — and it's been refined continuously through 2026, including a major April-2026 update that broke a lot of previously-working tools.
For Kill Switch specifically, that means:
- DNS lookups for the official domains are typically poisoned
- Direct TLS connections to known endpoints are reset mid-handshake
- Standard VPN protocols (OpenVPN, WireGuard) are detected and dropped within minutes
- HTTPS traffic to "innocent-looking" hosts gets through unchanged — *if* you can convince the GFW that's what you are
OxeraVPN's primary protocol — VLESS + Reality — does exactly that: it shapes your VPN traffic to look like a normal HTTPS visit to a real, legitimate website. The GFW can't tell the difference, and Kill Switch works as if you were browsing from outside China.
Step-by-Step Guide
1. Download OxeraVPN before entering China
This is critical. The App Store and Google Play in mainland China don't carry international VPN apps. Download OxeraVPN before you arrive, or grab the Windows portable .exe from our website (it stays accessible without a VPN):
2. Create your account
Visit dashboard.oxeranet.cloud. The Recon Protocol free plan includes 10 GB on a 30-day trial — enough to test Kill Switch end-to-end before paying anything.
3. Connect to the right server
From most parts of China, the best options are:
- Seoul servers — typically 56 ms from Chengdu, fastest overall
- Hong Kong servers — fastest from Guangdong province specifically
- US servers — only when Kill Switch is locked to a US-region account
4. Enable the Kill Switch
In OxeraVPN settings → Kill Switch → On. This guarantees that if the tunnel drops unexpectedly, your real IP never leaks — your internet just stops until the tunnel re-establishes.
5. Verify everything
Once connected, open whatismyip.oxeranet.cloud — your IP should match the server you picked. If not, switch protocols (VLESS ↔ Hysteria2) and reconnect.
Performance Tips for China
- Pick the right protocol for the day. VLESS + Reality is most reliable. Hysteria2 is faster on weak mobile connections and during periods of increased GFW filtering (often around politically sensitive dates).
- Server proximity matters more than headline speed. A 56 ms latency to Seoul is the difference between smooth Kill Switch use and frustrating buffering.
- Peak hours are real. GFW filtering is most aggressive in the evenings (8–11 PM China time). If you hit issues, switch servers or protocols.
Is It Safe to Use a VPN in China?
For foreign nationals, VPN use sits in a legal grey area. Authorities have stated that only government-approved VPNs are technically legal, but enforcement against individual foreign users is essentially nonexistent. Tens of thousands of expats, students and business travelers use VPNs in China daily without incident.
The realistic risk to an individual user is extremely low. The greater risk is traveling to China without a VPN and finding yourself cut off from your work tools, family, and information sources.
Frequently Asked Questions
How fast will my connection be?
On a healthy 500 Mbps home line in Guangzhou, expect roughly 138 Mbps of usable VPN throughput on VLESS to Hong Kong — enough for 4K streaming and HD video calls. Latency to nearby Asian servers is typically 29 ms.
Is OxeraVPN really free to try?
Yes. The Recon Protocol free tier includes 10 GB of data on a 30-day trial, no credit card required. It's enough to verify Kill Switch works in your real conditions before paying anything.
Which protocol should I use for Kill Switch in 2026?
VLESS + Reality for stealth, Hysteria2 for raw throughput on lossy networks. Both ship with the OxeraVPN app — pick from the Settings panel.
How do I tell if the GFW is interfering with my VPN today?
If TCP-based protocols connect but feel slow, while UDP-based ones (Hysteria2/QUIC) drop entirely — that's classic GFW UDP throttling. Switch protocols and the issue usually resolves within seconds.
What's the fastest way to get started?
Sign up at dashboard.oxeranet.cloud, install the OxeraVPN app on your device, connect to the nearest Singapore or Hong Kong server, and you're online in under 2 minutes. The free plan is enough to test Kill Switch end-to-end.
The Bottom Line
Reliable internet in China requires a VPN that was built for China — not adapted for it. OxeraVPN's VLESS + Reality protocol was designed specifically to bypass the Great Firewall, and it's the same protocol used daily by tens of thousands of people who depend on reliable internet from inside mainland China.
