Rancher vagrant hosts disconnect are network agent start

hi all,

been playing with rancher (latest release) to build a local building system.
start rancher hosts works perfectly, but by the time i’m trying to deploy a container, a lost the host.
i’ve found that it should be related to the network agent as before the network agent deploys, i can ping from any rancher hosts the rancher-server.

i don’t know how and why , but it seems the network agent breaks network connectivity between the rancher hosts and the rancher servers (ping 172.19.8.100 give host unreachable).

anyone ever had the issue ?
any clues on fixing maybe ?

Thanks a lot for the awesome piece of work, everytime i play with a newer version of rancher, it really gets better and better ! keep going guys !!!
