Can't access docker container on virtualbox from Internet

I have ToolBox installed on Windows 10.
Have created machine, and Nginx container, opened outside on port 8000.

Docker machine's IP is 192.168.99.100, container's IP is 172.17.0.2.
I can access Nginx from Windows as 192.168.99.100:8000. Even more, I can access from Windows host directly to 172.17.0.2:80. Also I can access Internet from inside the container.

At all the configuration is as following:

Container (Nginx)           Docker Host (VirtualBox)            Host (Windows 10)                                                     Router
172.17.0.2:80 <-----------> 172.17.0.1 (docker0)
                            10.0.2.15 (eth0)
                            192.168.99.100:8000 (eth1) <------> 192.168.99.1 (Ethernet 2, VirtualBox Host-Only Ethernet Adapter)
                                                                192.168.1.3 (Ethernet, Intel Hardware Adapter) <--------------------> 192.168.1.1
                                                                                                                                      <Internet static IP address> <-----------> Provider

The problem is that I can't connect Nginx ouside of Windows host. Tried telnet 192.168.1.3 8000 from router - connection refused. I have no any antivirus on Windows machine, and firewal is switched off.

Solution 1:

After a time have fount solution myself :)

VirtualBox -> Machine settings -> Network -> Adapter 1 (NAT) -> Advanced, Port Forwarding

Add rule like http on the screenshot:

Rule ssh has been automatically added by docker-machine create. The last quesion is how to add http rule automatically when docker creates container with ports exposed.
