I am using OS X v10.10 (Yosemite) and Cisco Anyconnect (which are apparently a bad combination for using boot2docker), and the following finally worked for me (thanks to the linked GitHub issue comment):

These steps will add a port forwarding rule and modify your environment to have Docker point to 127.0.0.1 (instead of 192.168.59.103 or other NATed IP address).

First - boot2docker needs to be installed, but not running.

If it is currently running - stop it now:

boot2docker down

Add a rule to forward traffic from 127.0.0.1:2376 to port 2376 on the boot2docker vm:

vboxmanage modifyvm "boot2docker-vm" --natpf1 "docker,tcp,127.0.0.1,2376,,2376"

Start boot2docker:

boot2docker up

Set default DOCKER environment variables:

$(boot2docker shellinit)

Override the DOCKER_HOST variable to point to 127.0.0.1:

export DOCKER_HOST=tcp://127.0.0.1:2376

Now you should be able to run docker commands:

docker version
