Since about 2023-08-07 03:00 UTC, there has been a rash of reports on NTC about blocking of foreign OpenVPN and WireGuard VPN connections. Connections that worked yesterday do not work today. Many ISPs are affected.
It seems that attempted connections periodically disconnect and reconnect. Some posters have reported that the trigger is a threshold of data packets after the handshake.
There are also posts mentioning problems with IPsec and L2TP.
Правила для блокировки совпадают с правилами для блокировки Amazon. Таким же образом блокируют Hetzner:
15 пакетов с датой через OpenVPN
2 пакета с датой через WG
The rules for blocking are the same as the rules for blocking Amazon. Hetzner is blocked in the same way:
15 packages with data via OpenVPN
2 packages with data via WG
Владимирская область, не работает openvpn и wireguard на Теле2 и Тинькофф. Подключение проходит, интернета нет. Если подключаться с домашнего интернета от Ростелекома, то все нормально. Сервер расположен в США
Vladimir region, openvpn and wireguard do not work on Tele2 and Tinkoff. The connection passes, there is no Internet. If you connect from the home Internet from Rostelecom, then everything is fine. The server is located in the United States
москва, tele2, рвётся соединение в германию, на порту 50001
проходит несколько пакетов и затыкается
причём, два пользователя нормально сидят, а третий уже не может достучаться
Moscow, Tele2, the connection to Germany breaks, at port 50001
Several packets pass through and shut up
Moreover, two users sit normally, and the third can no longer reach
очень странное поведение на теле2 - два пользователя работают по опенвпн с хецнером, а третьего выкидывает
но третий раздаёт себе интернет того же теле2 с такой же корп-симки - и всё работает
как будто только 2 соединения установить можно каждому абоненту
Very strange behavior on Tele2 - two users work on OpenVPN with Hetzner, and the third throws out
But the third distributes the Internet of the same Tele2 with the same corp SIM card - and everything works
As if only 2 connections can be established by each subscriber
