these are 2 local subnets. There is no path between them. You have to create a route, and I can guess from you post, that it is a task above your skills.

You either create a route in the router, or manually add it to both your hosts.

Or, in a much simpler way, assign a public ip to the given container.

You may be able to solve the problem a lot more simply (without any “advanced” networking) by using docker run -p or docker run -P. Those can give you ports on the host that let you reach your container from other machines on your network.
