I followed https://docs.openstack.org/kolla-ansible/latest/user/quickstart.html (quickstart guide) for all-in-one node installation, i got all the containers up and running and noticed most things working except "network connectivity in external network"

ran init-runonce with below changes EXT_NET_CIDR='' EXT_NET_RANGE='start=,end=' EXT_NET_GATEWAY=''

globals.yml -> http://paste.openstack.org/raw/769977 ovs-vsctl show -> http://paste.openstack.org/raw/769978

i could see instances are able to ping each other , within router namespace i can ping floating IPs assigned to instances but not any LAN IPs.

I have no clue on what to check next, looking for some help.

It's not clear what your problem is.

i can ping floating IPs assigned to instances but not any LAN IPs

What do you mean by LAN IPs?

Can you access instances via floating IP when you are not in the router namespace?

Can instances reach outside addresses?

LAN IPs, any IP in subnet Say my desktop which is Yes, I can access instances via floating ip when i do ip nets exec <ns name=""> ssh cirros@<floatingip> No, Instances not able to connect outside address. when i do traceroute last hop is instance floatingip itself

You mean that the Kolla host can't access other devices on This looks like the wiring to the external network went wrong. Show me the output of ip a.

Can you access floating IPs when you are not in the router namespace?

To what networks are eno1 and eno2 connected?

My bad. No, not able to connect to floating IPs from kolla host when not in router namespace. eno1 and eno2 connected to same switch. Even i was thinking a wiring problem and verified by assigning IP to eno2 and noticed it works.

"ip a" output http://paste.openstack.org/raw/770640
