I am following this nice guide to configure Quantum. https://github.com/mseknibilel/OpenStack-Folsom-Install-guide/blob/GRE/2NICs/OpenStack_Folsom_Install_Guide_WebVersion.rst my ttylinux VM is successfully reaching internet, ping 8.8.8.8 successfully. Although iptables got a DNAT rule by Quantum. Chain quantum-l3-agent-PREROUTING (1 references) target prot opt source destination DNAT tcp -- 0.0.0.0/0 169.254.169.254 tcp dpt:80 to: 1.2.3.4:8775 I got timeout on HTTP request to 169.254.169.254 connecting from VM. $ wget http://169.254.169.254/2009-04-04/meta-data/instance-id Connecting to 169.254.169.254 (169.254.169.254:80) wget: can't connect to remote host (169.254.169.254): Connection timed out But I got 404 Not Found if I connect to public IP port 8775 connecting from VM. $ wget http://1.2.3.4:8775/2009-04-04/meta-data/instance-id Connecting to 1.2.3.4:8775 (1.2.3.4:8775) wget: server returned error: HTTP/1.1 404 Not Found Anything I can try for debug/solving it ?
