Subject Cloudbr1 not connecting to network(Public or private network), hence SSVM not connected to outside world
Date Fri, 28 Oct 2016 00:11:50 GMT
Hi, i am having a problem on network bridging. I had found that my cloudbr1
doesnt connected to any network, hence my SSVM and CPVM cant ping DNS or
Gateway excluded the management server althiugh the status is up and
running. So i can't downlod any ISO. I have flush my IPTABLES on host
machine trough $sudo iptables -F but its change nothing. Any suggestion on
networking setup including during zone creation since my SSVM or CPVM eth2
seems doesn't acquire public ip like 203.XX.XX.XX instead of 172.16.XX.XX.
Is it necessary that eth2 must to acquire public ip like 203.XX.XX.XX  in
order to make SSVM or CPVM connected to outside world since i also doesnt
know my public gateway instead of private gateway which is 172.16.xx.xx.
Any other fix suggestion are most welcome. Below is my current network
setup. Btw I have management server and host in same machine. Thank you
