VPN and docker. How to redirect local traffic?

Question

linux

When connecting to a VPN, access to forwarded ports from docker is lost.
I’ll make a reservation right away that a vpn client of one provider is used and it does not have the ability to configure tunneling to ip.

I raise sites locally on domains like example.localhost (in fact 127.0.0.1: * )
As I understand it, through iptables it should be possible to redirect all traffic when localhost is tapped to a regular subnet.
Actually, how to do it?

Answer 1

1. Create a network.
2. Address containers using the container's internal IP.
