How to connect to a VPN server through a proxy?

Question

Computer networks

Hello!
There is a need to connect to a VPN to bypass blocking. Just the other day, the provider set the DPI apparently. All ports and protocols no longer work. It is impossible to connect to the vpn server, or it is possible, but only once, after disconnection, the port or protocol is tightly blocked. In any case, that's how I see it. Not an expert, I could be wrong.

Just in case

PPTP, l2TP, ipsec, SSTP, OVPN do not work on any ports

I heard from the corner of my ear that you can connect to a proxy, then to vpn and then dpi will not block anything.
The main condition : - do everything on RouterOS (CHR). Clients too RouterOS
There is already a Server on RouterOS(CHR) with configured VPN servers. The next question is about the proxy.
Maybe someone knows articles on the Internet with guides, or right here can help me. I will be very grateful!

Answer 1

sudo apt install tor privoxy obfs4proxy You
install according to my manuals, obfs4proxy obfuscation will work even because of the great Chinese firewall, because the bridges are encrypted, sir ... and already your provider does not know where you are breaking into. It is also possible to change the country of the output node for greater stability.

Then the privoxy port 8118 (well, or whatever you like) thrown into the LAN (0.0.0.0/24) is driven via http into proxifier (this is a program for proxying traffic on Windows) and the whole traffic, including traffic from the VPN client, will go through your own completely free and unlogged proxy server even to the moon, if they implement the OSI model. Don't thank.
