Here are my filter tables...
I did a default installation of 1 controller and 1 compute following
openstack install docs.
I read through that the firewalld was not stopped during
installation. I'm not sure if that could have cause some invalid
insertions/deletions into iptables.
Probably, you may want to consider re-installing controller and
compute nodes with firewalld disabled in the beginning unless you
have enough time to troubleshoot the problem.

Subject: Re: [Openstack] DHCP Request Failed on Ocata
Any ideas on this?
Here are my firewall rules on Controller Node:
#ALLOW ALL Compute Node
-A INPUT -s $COMPUTE_NODE_IP/32 -p udp -j ACCEPT -A OUTPUT -d
$COMPUTE_NODE_IP/32 -p udp -j ACCEPT -A INPUT -s
$COMPUTE_NODE_IP/32
-p tcp -j ACCEPT -A OUTPUT -d $COMPUTE_NODE_IP/32 -p tcp -j ACCEPT
#ALLOW ALL from-to Public Subnet
-A INPUT -s $PUBLIC_SUBNET/29 -p udp -j ACCEPT -A OUTPUT -d
$PUBLIC_SUBNET/29 -p udp -j ACCEPT -A INPUT -s $PUBLIC_SUBNET/29 -p
tcp -j ACCEPT -A OUTPUT -d $PUBLIC_SUBNET/29 -p tcp -j ACCEPT
After these more rule are following for SSH (port 22) , HTTP (port
80) etc.
Repsectively on Compute Node I have
#ALLOW ALL Controller Node
-A INPUT -s $CONTROLLER_NODE_IP/32 -p udp -j ACCEPT
-A OUTPUT -d $CONTROLLER_NODE_IP/32 -p udp -j ACCEPT
-A INPUT -s $CONTROLLER_NODE_IP/32 -p tcp -j ACCEPT
-A OUTPUT -d $CONTROLLER_NODE_IP/32 -p tcp -j ACCEPT
#ALLOW ALL from-to Public Subnet
-A INPUT -s $PUBLIC_SUBNET/29 -p udp -j ACCEPT
-A OUTPUT -d $PUBLIC_SUBNET/29 -p udp -j ACCEPT
-A INPUT -s $PUBLIC_SUBNET/29 -p tcp -j ACCEPT
-A OUTPUT -d $PUBLIC_SUBNET/29 -p tcp -j ACCEPT
After these more rule are following for SSH (port 22) , HTTP (port
80)
etc.
where on all the above:
The $COMPUTE_NODE_IP is the static IP address of the compute node
The $CONTROLLER_NODE_IP is the static IP address of the controller
node
The $PUBLIC_SUBNET is the subnet for the public IP addresses as
defined
by my provider
The above rules are on the top of my IPTABLES files immediately
after:
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
while at the very end (after all the rules) I have:
-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT
Using the above rules I believe that I have an open communication
between the Controller, the Compute Node and the VMs.
Obviously I am missing something...but what???
Can someone help me or share with me its firewall rules between a
controller and a compute node??
Keeping the firewall disabled solves the problem and all VMs are
getting IP addresses without a problem, but this is not desired.
I really appreciate any help provided since I am puzzled for quiet
a
few days now with this....
Regards,
G.
I have also disabled completely the "firewalld" service and
reverted
back to "iptables" service but without success.
No matter what I do my instances cannot get a DHCP address unless
the
firewall is "stopped".
I 've tried to add the UDP ports 67-68 on the firewall but without
success as well.
What else should I do in order to be able to have "iptables"
enabled
for basic firewall functionality and at the same time my OpenStack
environment to work without a problem?
Any ideas???
Regards,
G.

Has anyone configured OpenStack on CentOS with Firewalld or do
you
suggest to disable it?

Hello!
I am trying to setup a new Ocata installation following the
official
guide but my instances fail to get a DHCP address.
I am using two physical nodes (1x controller and 1x compute)
each
one
with two network interfaces.
Compute node can reach the Controller node via the first
interface
and vice versa.
As recommended by the manual the second interface is unnumbered.
When I launch an instance I can see using "tcpdump" that the
DHCP
request reaches the second (the unnumbered) interface
of the compute node but never reaches any other interface either
on
compute or controller node.
Therefore I am wondering how should the instance get an IP
address?
What is the correct path that is followed?
I have tried that using both provider and self-service networks
and
the result is always the same.
Looking forward for any directions, recommendations etc.
All the best,
G.
