1.  Can you send UDP packets across your LAN?
If not, check your client machine.

2.  Can you send UDP packets across the Internet to another host?  (This may 
require the co-operation of another party.)
If not, check your router.

If you can send UDP across your LAN and across the Internet but not to your 
own box in Rackspace, it must be a routing issue at the Rackspace end.
