I looked at your Information as well, and used it as a guideline.

I managed to solve the issue of Internet connectivity by enabling routing on my bridge with iptables

I followed the Instructions you provided to the T, but I dont seem to be able to reach the Internet from my Instances,

I can ping my eth0 addr from inside the instances but do not reach the Gateway of my public net

Ok I have had some progress,

after searching more and finding some old, but still usefull guides I managed to rerun the packstack install to a (mostly) working configuration.

I know have and the following situation, the bridge br-ex has 2 Ip adrresses, 1 is my "normal" (former eth0) IP Addr for Internet access and the second is the "external" Openstack IP Add( in my case 10.0.1.1/24), openstack has the internal network 10.0.0.0/24 for the Demo User as well, so now if I start an Instance it correctly gets an IP adrr from the 10.0.0.0 internal Net, and if I add a Floating IP from the 10.0.1.0 Net I can also reach the Instance from my HostVM, which is running the openstack cloud.

1 Probem persists so far though, I still cant access the Internet from inside the Instance, and if I enter the router Namespace with "ip netns exec ..." and ping from the router to 8.8.8.8 I get a redirected Host notification (Nexthop beeing my eth0 Gateway)

I would love to solve this.

2019-10-09 08:36:39 -0500 问了问题 Packstack Stein - Networking Configuration

Hello,

I want to install a POC Openstack installation by using packstack, after running the packstack installation (allinone) and tweaking the answer file a bit to my setup and what services I want to deploy I managed to have an Openstack cloud running, upload images and start some instances (although I am having trouble getting to run Windows Instaces)

My Main problem though is the Networking aspect of Packstack and Openstack, my VM on which i wanted to install the system has 1 physical Interface(eth0) with a static IP that has Internet Access.

Now Packstack creates the br-ex by default and gives it the IP-range 172.18.24.0/24, I figured that this Network is used to deploy Instances, but when I start an Instance it doesn't get an IP from the DHCP and even if I configure a static one from the pool of 172.18.24.0/24 addresses I can't connect to the internet nor can my Host VM connect to the Instance

I looked over some guides online and the packstack answer file configuration options in the Network section, but haven't figured out what to do, to make it work.

My thought was that openstack uses its own Network (some private IP range) and the connection to the internet is managed by routing traffic through my HostVM, but haven't found anything online yet that lets me accomplish that If by chance anyone can give me a quick guideline what settings to use for the packstack deployment to make it work, that would be great.
