Open Stack

Hi Nidhi,

Try this :

*Set up the network environment on the host so that devstack VMs can access
the external world.*

*sudo bash*
*echo 1 > /proc/sys/net/ipv4/ip_forward*
*echo 1 > /proc/sys/net/ipv4/conf/INTERFACE/proxy_arp*
*iptables -t nat -A POSTROUTING -o INTERFACE -j MASQUERADE*

*These command will make sure that network traffic will be correctly routed
in and out of the devstack VMs.*
*The ip_forward and proxy_arp changes will be reset when the machice
reboots. You can make these changes permanent by editing /etc/sysctl.conf
and adding the following lines:*

*net.ipv4.conf.INTERFACE.proxy_arp = 1*
*net.ipv4.ip_forward = 1*

*Replace INTERFACE with ethernet interface of your virtual box.*

Hope it will work as it works always for me.

Regards,
Ganpat
