Open Stack

 If I do an :

 arping -U -I etho x.x.x.x

 where x.x.x.x is the IP address.

 I can almost immediately access them outside of the subnet!

 Do you mean that OpenStack is sending a gratuitous ARP for all
 and the router is ignoring them unless it is for a specific IP address?

 If this is the case is there anything I can do?

 Regards,

 George
