2014-02-26 10:52:41 -0500 asked a question what filters spoofed traffic?

When sending a packet with a spoofed source ip from an instance running on a compute node I noticed that the compute node is able to see the packet on vnet0 but not br10. I am running nova network and havana.

What is preventing br10 from receiving the packed containing the spoofed ip address?

Please note I am using: sysctl -w "net.ipv4.conf.default.rp_filter=0" sysctl -w "net.ipv4.conf.all.rp_filter=0"

2014-02-07 13:07:44 -0500 asked a question heat fetching remote template via proxy

I attempted to create a wordpress stack using a template I had already downloaded, however, during creation a fetch request occurred for another template (and I require a proxy server to download anything).

Does anyone know how to inform heat to use a proxy server to download templates (or where on disk it will look for other templates it might need)?
