How to configure PPPTP (VPN) on Mikrotik with binding to ethernet port?

Question

VPN

Good afternoon!
There is such a device MikroTik CRS109-8G-1S-2HnD-IN, which raises the PPPOE connection to the provider. Several clients are connected to it by wire and WiFi is up.
It is necessary to raise several different PPPTP VPN connections on Mikrotik and bind them to a specific ethernet port, in the event of a ppptp connection drop, traffic should not go through the main PPPOE connection (this particular client has no Internet).
Example: we create a ppptp client connection to a remote server and wrap all traffic from ether2 to this connection, if the connection drops, the traffic does not go. There should be about 5 such connections.
WiFi connections go to the Internet directly through pppoe.
It turned out only to raise the PPPTP connection, it didn’t even work to turn the traffic into it. Based on instructions from https://support.hidemyass.com/hc/en-us/articles/20...
Thanks in advance
