How to connect to multiple VPN servers?

Question

VPN

There are services, they have VPN servers. They give access, for example, in the form of configs to openvpn, keys, etc. Openvpn is launched with a certain config and then all connections go through the corresponding server. To change ip we change a config. Let this principle be "consistent".
What you need:
You need to be able to "parallel", simultaneous access to all VPN servers.
My view of the end result:
The abstract software package should get some local address 127.x.x.x:5656 as socks5 and connect to the site through one of the above VPN servers (depending on the local address). I think you first need to have a socks server that will listen to addresses and somehow proxy it all ...
Tell me the recipe how to cook all this correctly and is it possible.
If possible, then clearer, tk. in question is not strong as you can see.

Answer 2

Not quite clear.
But if I understand correctly, it’s enough to make several TAP adapters, and accordingly launch several openvpn instances, and set up routing so that the packets are not all in one link, but to different addresses through different links.
