Raised own OpenVPN server on Ubuntu 16.04. So the problem is that there are two computer in LAN: one for the Wi-Fi signal, the other twisted pair. Which Wi-Fi everything is OK, OpenVPN works on blocked sites comes. Which wire connects OpenVPN, the IP address changes, DNS too. But blocked sites comes with Russian IP, all locks work. Moreover, the components are reversed, ie put the first wire, the second Wi-Fi. The problem is on connecting through the wire.
Tried to push open the ports on rouette (ZyXEL), firewalls and antivirus programs are not.
The same problem was with the connection l2tp+ipsec vpn, but the problem was resolved by disabling ipv6 in the settings. Here so decided not to.
