 Once that's done, you need to set up a SSH tunnel between your host machine and the vagrant machine that's running Docker. This can be done by running the following command in a host terminal:
 
 ```
-ssh -L 4243:localhost:4243 -p 2222 vagrant@localhost
+ssh -L 2375:localhost:2375 -p 2222 vagrant@localhost

-(The first 4243 is what your host can connect to, the second 4243 is what port Docker is running on in the vagrant machine, and the 2222 is the port Vagrant is providing for SSH. If VirtualBox is the VM you're using, you can see what value "2222" should be by going to: Network > Adapter 1 > Advanced > Port Forwarding in the VirtualBox GUI.)
