Why doesn't China's firewall block traffic like this?
- yorwba 7y agoBecause the Great Firewall operates as a blacklist and is only intended to prevent commoners from learning censored information. If Zoom meetings where anyone can join became a popular source of unfiltered news, they'd either ban Zoom or require that a two-class system is set up to prevent ordinary Chinese users from using Zoom to communicate internationally, similarly to how Douyin (within China) and Tiktok (everywhere else) are two separate silos. But people from other countries connecting to servers in China is not something the Great Firewall tries to interfere with.
- devttyeu 7y agoFrom my experience it's not just a blacklist, any non-blessed traffic is slowed down to a crawl (on the order of double digit kbps). This also applies to getting content from China. (that said, it's pretty reasonable to assume Zoom is not throttled given how important it is in the buisness world)
- captn3m0 7y agoSo who’s making a tunnel on Zoom calls then? A network interface with WireGuard behind a fake camera interface on a relay node?
- debian3 7y agoRent a vps on alibaba cloud in China, try to scp a file. Last time I tried it went from slow, to really slow to a complete stop. The file was not even big...
- rayvd 7y agoDid you try on a non-standard port too?
- kerng 7y agoWhy would they want to block this traffic? It's perfect for intelligence gathering. Lots of IP that can be grabbed for free.
