Investigation and the reasons:

1. Firewall

   Firewall beginning has been that there is a problem, tried firewall container, simply can not operate because there is no authority, off the host firewall, the fault persists

2. routing

   Many say that the Internet routing problem, start thinking about the investigation, is not host to a container route blocked, then add a route

   route add 172.17.0.0 mask 255.255.0.0. 172.17.0.1 not

   route add 172.17.0.0 mask 255.255.0.0 192.168.0.149 host IP149 not

   Saw a docker settings

docker bridge, the gateway is 10.0.75.1 try to add this route

C: \ WINDOWS \ system32> route add 172.17.0.0/16 mask 255.255.255.0 10.0.75.2 -p
operation is completed!
