Ghost running on docker container does not respond to http requests from other container

Question

I am setting up a ghost blog instance inside a docker container. I bound the ghost server to host 0.0.0.0 and exposed the port on which it's listening (port 2368). If I run wget to the ghost container's ip and ghost's port from the outside, the index is fetched, but if I run wget from within another container using the exact same ip and port, wget reports

--2014-03-20 02:58:27-- http://172.17.0.5:2368/ Connecting to 172.17.0.5:2368... connected. HTTP request sent, awaiting response... 

and hangs indefinitely. I want to be able to connect to the ghost instance from within another container because I'll be using the second container as a reverse proxy with nginx (I'm using wget because I want to test connectivity since my attempts with nginx resulted in Gateway Timeouts). Is this expected or does ghost require additional configuration to serve content to another docker container?

Update

I forgot to mention that the 'reverse proxy to be' container is linked to the ghost instance container.

If the nginx setup is going to be for the life of your ghost blog then you might want to use the docker feature of linking containers.
