[rdo-list] Can't ping Gateway, etc.

Hello, 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
