Re: PREROUTING 169.254.169.254 rule shoud not on Compute node.......

 

Hi,

this is an issue in our Multi-Node arquitecture of the Stackops
Openstack Nova Distro. We have not verified 100% yet if it fix the
issue, but I think Hugo has found the reason and the solution, so my
sincere kudos, Hugo.

We will release a maintenance release once we verify that the rules
works fine in our lab.

Regards
