So they wouldn't be accessible.

Then the USA and Europe join in on it as well?

Re: Using VPNs to avoid censorship blocks


[re: RobertoS] [link to this post] 		 
Protocols often use standard ports. Suppose an ISP wanted to block all web traffic. The web uses ports 80 and 443. If you blocked those ports, the web would not work. But before long, someone will provide a proxy to get around it. So the ISP would need to block that port too. But now it's becomes a game of whack a mole.

So the ISP needs to read the traffic, and decide what it is. For unencrypted web traffic, that is easy. As soon as they see that the data is web data, they can block it, regardless of what port it is. BUT, if you encrypt the traffic first, the ISP cant know what the data is.

Now suppose the government imposed a license on VPN. What is to stop you from using an encrypted VPN from say the USA, The government cant tax that.

So all ISPs have to block all VPNs other than the ones the Government says are ok?

That's very draconian. There are lots of VPNs worldwide. A businessman from Sweden would travel to UK and find he can't connect to his work's VPN in Sweden because the British Government has gone nuts.

So are you saying it is impossible, or just fairly complex?

Technically possible, but in practice completely unworkable.

If the government were to require all ISPs to block all internet traffic other than that which they "licence" then sure, it's technically possible.
