Hi all. were you able to fix this issue. I am running into the same issue using RHEL 7.1 and their packstack all-in-one installation using NOVA networking I can ping between the instances and ssh from host to the instances. But I cannot route out of the bridge interface so my questions 1. do you need NAT configured? 2. do you need IP tables setup, mine is currently disabled Any assistance would be appreciated rgds, jedd
