I've always wondered how the Chinese government censors their internet. A few weeks ago I went to google.cn and then typed "communism sucks" in the search. it returned plenty of anti-communism links.
Well, probably because it's easier to have some computers dedicated to scanning packets, while having others dedicated to do actual routing. If the computers handling routing also have to deal with scanning the packets themselves, that adds a layer of complexity that would likely have a fairly significant effect on the speed of connections.It's pretty trivial to break a connection if you can watch its packets, so that's probably why they went this route. Although I suppose you could start ignoring those packets like Bruce suggests, this would have to happen on both sides of the connection. That would be fairly tricky to get going on a large scale, breaking a lot of things in the process, and even if it were done, the Chinese government would just change tactics on how they disconnect users. There are a lot of other wise you can effectively kill connection.

I should think harder first - it's probably because the router would get flooded with attempts to resend the packet.

I'm using Freedur now. It is super fast and stable. And it is cheap. The best I've ever used
