Hi Stéphane, Can you tell us if your VM are one the same host? Do you have two different (virtual) routers to access the 134.214.213.0 and 134.214.32.0 networks? Did you check the path of a ICMP packet with tcpdump? Cheers, Jerome Le 09/11/2017 à 16:29, Stéphane Delmotte a écrit :
I have a problem with network on my cloud.
Some VM (depends of project) use floating ip from public01 and other from public02
My vm on the network public01 work perfectly and can reach the controleur (134.214.34.20) (it is on the same network in my case 134.214.32.0/22) (it use floating ip)
my vm on the network public02 work perfectly and can reach all host on the netwok 134.214.213.0/24 and 134.214.32.0/22 exept the controleur (134.214.34.20) why ?
there is my configuration 2 providers networks public01 and public02

I need my VM (ip form public02) can reach the controler because I use a cloud broker sleepstream and my vm (on the network 134.214.213.0/24 need connect the API 134.214.32.0/22 because some of them can be orchestrator).
I need somme help thanks Stéphane
