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 ?

Thanks.
