instance cant access internet
Hi every one. I just installed Openstack Kilo RDO AllInOne on Centos 7 with packstack(my Centos is virtual machine run from HyperV). I have problem with network. My network:
Centos: 10.x.x.242/26 (physical network with internet)
Private network: 192.168.1.1/24
Public network: 10.x.x.192/26 gateway: 10.x.x.194 (same physical network)
I have been floating IP 10.x.x.252/26
for instance but it couldn't ping to 8.8.8.8.
Please help me, thank you.

Did you add proper Security groups for the Instance ?
Yes, I opened icmp and ssh for instance
Hi, if it is possible try keeping the subnet as 16 for all your network.
Thank you. I have edited all network subnet as 26, it no change. From instance can ping to router external IP, I try traceroute and it stuck at floating IP. Can't ssh instance from
10.x.x.192/26
, too.
