How to connect from one PC to 2 VPNs behind one white IP?

Question

System administration

Tell me, there is a remote network, white IP 78.78.78.78 (all IP & PORTS are fictitious).
Behind the white IP are two windows servers with VPNs up (vpn is configured as a point to point).
Remote network - mikrotik is outside on it forwarding inside
1723=>192.168.1.10:1723 for the first server (working).
1722=>192.168.1.12:1723 for the second server.
How to set up a VPN connection on windows 10 on a second server.
for the first one, we simply configure the VPN as standard to the address 78.78.78.78 - Works
Version: for the second one, you need to use a non-standard port 1722.
in the form 78.78.78.78:1722 - it does not work (perhaps this format is not provided).

What are the options?

PS: Do not offer the network-network configuration option. The scheme is needed - if one server dies, so that there is an opportunity to go to the second server. And I would like to solve the built-in solutions.

PS2: I don't know if it's possible or not - on the PC in the firewall somehow drive one of the VPN connections to another port 78.78.78.78:1722

Thank you

A point-network is not suitable? Although perhaps you meant it by "network-network"?
On Mikrotik VPN with network forwarding, in your case 192.168.1.0.
Your windows 10 connects via mikrotik vpn and gets your network address. Then connect to any node on your network.

If you tried to connect at the same time - it's more likely a problem with routing. There cannot be two routes for one ip.
