Problem with oc cluster up

After installing the latest (1.5.1) to /usr/bin folder, I am getting the following error, when running oc cluster up:

-- Checking container networking ... FAIL
   Error: containers cannot communicate with the OpenShift master
   Details:
     The cluster was started. However, the container networking test failed.
   Solution:
     Ensure that access to ports tcp/8443 and udp/53 is allowed on 192.168.178.90.
     You may need to open these ports on your machine's firewall.
   Caused By:
     Error: Docker run error rc=1
     Details:
       Image: openshift/origin:v1.5.1
