Hi Stephen, This is what I get... (note change of namespace etc as this machine is a VM that was recreated).
root@openstack:~# ip netns list qdhcp-3f0a3d53-f3a4-4da8-a5e0-1a97b6e51424 qrouter-f26858db-3ae8-431b-86a7-edab80834586 root@openstack:~# ip netns exec qrouter-f26858db-3ae8-431b-86a7-edab80834586 wget http://172.16.0.210:8775/ --2012-11-08 10:52:11-- http://172.16.0.210:8775/ Connecting to 172.16.0.210:8775... failed: No route to host. root@openstack:~# ip netns exec qrouter-f26858db-3ae8-431b-86a7-edab80834586 ip r default via 172.16.1.254 dev qg-c396e75e-38 10.5.5.0/24 dev qr-031aafac-19 proto kernel scope link src 10.5.5.1 172.16.1.0/24 dev qg-c396e75e-38 proto kernel scope link src 172.16.1.10 So it is a problem between my router and the physical network... That 172.16.1.0/24 is an "ext-net" network created with an external router. When I spin my instances up I use the 10.5.5.0/24 "int-net" network. I followed the instructions to add a route from http://docs.openstack.org/trunk/openstack-network/admin/content/adv_cfg_l3_agent_metadata.htmlbut I don't immediately see how the route add helped here - but it has raised an eyebrow. The output of the port-list gave me 172.16.1.10 to use as the $ROUTER_GW_IP - which is odd as that IP was set as my external floating range start IP. Doing a traceroute to the 172.16.0.201 address from the router namespace went via 172.16.1.10... so I've some things to play with for the time being... Thanks for your help so far. Is the Guardian looking at OpenStack for any projects (I'm from TMG)?
