(Hot) Potato routing Typically, a host connected to a network, such as the Internet, will have one default route and one Internet (WAN) interface.
A system uses its routing table to determine which network interface to use when sending packets to remote systems.
If a system has only a single interface, it is sufficient to configure the IP address of a gateway system on the local network that routes packets to other networks.
This works correctly for docker windows containers.
How to reproduce: Note: For windows, the call is correctly routed (1.243 ip address).
In other words: a packet is received on one interface and the reply is sent back via the other.
