How to route traffic through each VPN using a raised proxy server using a mikrotik router?

Question

VPN

Task: there are many VPN servers, you need to raise a proxy server and forward traffic to each VPN.
I see a connection scheme like this, there is a machine, through programs it connects to one proxy north, but on different ports, as a result we have 4 ip on one machine.
PC > Proxy:port1 > VPN1
PC > Proxy:port2 > VPN2
PC > Proxy:port3 > VPN3
PC > Proxy:port4 > VPN4
Is it possible to implement this scheme using mikrotik? and if this is not possible, then how else can traffic separation be carried out if there is a VPN. So far I have found only an option through 3proxy, but it will turn out to be extremely unstable. I don’t consider the option with several virtual machines, because now I use just this method and I want to get away from it in order to save server resources.

Answer 1

solve forwarding from one proxy to VPN and copy it four times))
for example, start with the more familiar IpTables - make a rule and colleagues will help convert it to microtic rules
Ps if cho, this is impossible, since different levels of the OSI model, but since now Proxies and by VPN shkolota understands HHR, maybe some kind of trick and go
