[Openstack] No ping or SSH to the instance


You can use

ip netns exec qroute-ID ifconfig
ip netns exec qroute-ID tcpdump -eni <some qr or qg interface>

to verify if packages are arriving. And, you can also use

ip netns exec qroute-ID iptables -L -n -v

to see where packages are being dropped (there will be counters on DROP
rules).
