I have RDO ALL-In-One installed.    I set up a private network and a public (external) network.     I set up a virtual router to connect the private network to the external network.    I have RDO installed on Centos 7 as a guest.  Windows 10 is my host OS.

When I move into the virtual router's namespace, I can ping the guest os's IP address (192.168.1.12) and I can ping the host os's address (192.168.1.11), but when I try to ping the gateway (192.168.1.1) it tells me it is unreachable.  It also fails when I try to pinggoogle.com

  I can ping the gateway and google.com from the root namespace of the guest os, centos 7.

 I'd appreciate any help on this problem!

  Thanks,

  ...John
