### configuring public network

Hiya, I installed fuel on virtual box running on my home computer. Out of the box the public network is set to

172.16.0.0/24
IP range: 172.16.0.2 - 172.16.0.126
gateway: 172.16.0.1

Neutron L3 floating ip range: 172.16.0.130 - 172.16.0.254


In this case the connectivity check is successful but I want the public and floating ip addresses to be on my home LAN so I can get to the VMs from other computers. The home LAN is 192.168.1.0/24. When I change the above to the following, the check fails.

192.168.1.0/24
IP range: 192.168.1.200 - 192.168.1.235
gateway: 192.168.1.1

Neutron L3 floating ip range: 192.168.1.236 - 192.168.1.254


The error is:

Verification failed.
Repo availability verification using public network failed on following nodes Untitled (49:e5).
Following repos are not available - http://archive.ubuntu.com/ubuntu/, http://mirror.fuel-infra.org/mos-repos/ubuntu/8.0/
. Check your public network settings and availability of the repositories from public network. Please examine nailgun and astute logs for additional details.


I don't understand why the check is failing. Shouldn't it be able to get to the internet when the public network is set use IP addresses that are in the home LAN? I don't see anything obvious on the controller (49:e5) node logs.
