Hey folks! I'm working on a setup with two separate bridge networks, each housing a Linux container. I'm trying to figure out the best way to facilitate communication between these containers. Is it necessary to spin up another Linux container to act as a router that connects both networks? Any advice would be really helpful!

One straightforward approach is to create a new network that includes both containers. This would allow direct communication without needing a separate router container.
For a more structured solution, consider using four containers across three Docker networks. You’d configure NAT, forwarding, and gateways to allow for communication between your two test containers on different LANs.
Another option is to use shared memory communication. You could mount a common directory that both containers can access.
If you're after a quick and dirty workaround, you could expose the containers' ports and communicate via `host.docker.internal` or the host's IP address. Just keep in mind this isn’t always a clean solution for every project.
While not typically recommended, you could set up a 'router' container that connects both networks. This could facilitate communication, but it might add unnecessary complexity.
