Dockamole
Example bridging connections across two distinct Docker networks using mole.
My real use case is something like a remote LDAP server that I don't want to expose to the public internet and some metrics servers only available behind a VPN. This setup will allow me to create a proxy container on a host that will act as a local LDAP or HTTP server.
Eg.
