Do you have any idea why the GFW blocks UDP by default? I can imagine that for corporate networks, but as far as I know, uninspectable UDP streams only recently came into existence with Google's QUIC (which assumes pre-negotiated encryption keys are still valid)
Why block all streams if you can inspect them (or at least their handshake)?
- duskwuff 12y agoProbably because they determined that most of it was VPN or other encrypted traffic, and that blocking it was easier than trying to inspect it.
- beefsack 12y agoWhile practically no official information exists publicly, this appears to be the reason. My gut tells me that the lack of structure in UDP makes it a little harder to inspect too.
