Hi, all,
I managed to make VMs(with IP address in the same sub-net) in a
RYU-controlled network ping each other successfully, now I want to make the
VMs could connect the Internet, here is my test: I assigned ip address 10.0.1.x
to the VMs while assigned the gateway ip address 10.0.1.1 to the Open vSwitch
bridge, and set iptables rules(SNAT) in the physical machine that run the Open
vSwitch bridge. However, the result is confusing, when the packets from VMs get
to the bridge successfully, it seems that the bridge only take actions like
Output, SetField, etc, but cannot pass the packet to the physical machine's OS
kernel to handle the packets and do NAT, is that true? In my test, I ping the
10.0.1.1 from one VM(ip: 10.0.1.2), the ICMP request packets get to the Open
vSwitch bridge, but the physical machine does no reply them.
Is there any one can help me, please ? Thanks a lot.
Best regards,
Kun Liu
