Hello!
I want to ask a question about Docker. I installed VMware Workstation 10 in Windows7 as host, and the guest OS is fedora 22 with latest updates. I installed the latest docker, and running sudo docker run -i -t centos:latest ping 8.8.4.4 But I found all the containers can not access wider Internet, I have tried fedora's docker, and official docker-engine, they all do not work.
I am using default docker0 bridge, and my network configuration is: Host OS(192.168.200.1) <--> VMware NAT(192.168.200.2) <--> Fedora Guest(192.168.200.137) <--> docker0(172.17.42.1) <--> container(172.17.0.4)
I can run ping from container with 172.17.42.1 AND 192.168.200.137 OK, but I can not access 192.168.200.2 and later networks.
I also installed other OS(debian) with the same VMWare configuration, the network works fine. So I figure whether it is fedora's problem.
Does the Vmware+fedora22 can fully support docker network and functions ?

Fedora guest needs IPV4 forward to be true? On Oct 11, 2015 22:02, "Nicol TAO" nicol_tao@126.com wrote:

Found the problem You should not use systemd manage your network, just default May networkmanager
