GlobalCheck reported that in some regions of Russia they began testing the blocking of popular VPN protocols. We are talking about L2TP, IKEv2 and IPsec.
IPsec is used to create a connection between a VPN client and a VPN server. According to the resource, in some operators (for example, Rostelecom) in the regions, IPsec does not even pass between the server and the client in Russia. The problems also concern IKEv2.
According to unconfirmed information, the Russian authorities have begun testing the blocking of popular VPN protocols in some regions. GlobalCheck notes that many administrators of corporate networks where this protocol is used are now looking for solutions to bypass the locks.
Earlier, Roskomnadzor began blocking popular VPN services. Currently, several dozen VPN services are not available in Russia. In most cases, free solutions were affected.
In many countries, VPN blocking is used at the state level. For example, “The Great Chinese firewall blocks VPN services “at the protocol level.” This means that the firewall does not need to identify each VPN provider and block its IP address. Instead, they detect passing VPN traffic and block it.”
China learned from the best when creating its firewall: American technology companies, such as Cisco, developed basic Internet traffic filtering tools that allowed corporations to control the work of their employees. After that, Beijing took these tools to a new level, and today the country has the most advanced censorship and surveillance system in the world – the GreatFireWall “Golden Shield”. To prevent people from connecting to websites or services that the Communist Party doesn’t like, the Great Firewall blocks website names, redirects traffic, and can even disable encrypted messages by figuring out what type of services the user is trying to connect to.
Currently, VPNs are banned in 10 countries – China, Belarus, North Korea, Turkmenistan, Uganda, Iraq, Egypt, Turkey, the UAE and Oman. In some countries, using a VPN is a criminal offense.
