Docker jenkins networking issue

I am using the window 7 os on which i have installed docker toolbox.
I started the docker from the docker quickstart terminal and pull the jenkins
image and started the container and open the jenkins server in the browser.
Now i have installed the docker plugin in the jenkins and try to connect to the docker
api server with the adress 192.168.99.100:2375 , but its giving error .
So do i fix this networking issue.
