Reversing GFW (Great FireWALL) is not a new topic, but it evolved over the years. Especially these past 3 years, things have changed and the WALL has become greater and stronger. As a person staying in China since 28th Jan 2020, this talk is to share the knowledge behind and over the WALL. Final goal is to reach the full capacity from the ISP and to gain access to the world.
The talk will cover:
-
Brief history of the WALL
-
Different types of WALL. Not only for outgoing traffic to real internet, but internally too
WALL for internal content WALL for data centers, VPS and etc 3. Method to bypass and intro to different protocols
VPN Not so VPN (Vmess, Vless, Trojan and etc.) 4. Deployment method, which clinent/server to choose from (v2ray, xray, clash and etc)
- Certain tricks that sometimes do not work
Why and how is this happening …

Why and how is this happening We do know when its not gonna work DNS pollution Additional lock period 6. Journey to start building a home router
Specs and software Which protocol to choose OS/Software maintenance How to make a non-zh_cn firmware non-zh_cn tooks Is Github able to help? Nodes to escape, how to choose Final goal – FULL speed to the world 7. DEMO and Quick video tour of the system
At the end of this talk, tools and firmware (non zh_cn mod) will be uploaded to Github. It will be free and open source. Hopefully these tools, firmware and experience are able to help those still suck behind the wall (eg, Iran).
