Hi Rafael,


Thanks for reaching out. I am not sure about traffic labeling and rest of t=
he stuff. I have just setup the basic installation using this tutorial http=
://docs.cloudstack.apache.org/projects/cloudstack-installation/en/4.9/qig.h=
tml and haven't explicitly set anything that is not in the tutorial. About =
the IP addresses of VM's. Yes, they seem to have a single IP (ifconfig). Pl=
ease note that I am creating VM's from cenots 6.8 minimal ISO image that I =
intend to use later as template. Does that create the problem?


Adeel

I asked a clarification because anything is a VM/instance (system and
users), I wanted to know if the VMs without access were either a system VM
(VR, SSVM, CVM or others) or a user VM.
Well, what is your setup? Are you using basic network where the public IP
is assigned directly to users VMs?

I asked you about the traffic label you are using for the public network.
System VMs get IPs on management and public networks. The SSVM has also an
IP on storage network. So, it seems that everything is fine with your
public networks, not so sure about the rest.VMs get an IP on Guest network.
The basic zone setup you will set the Guest IP as the public network (with
external access). Do these VMs have only a single IP?
