under same net. Can you tell me one thing? When I call to 127.0.0.1 to my
local Asterisk server it works. When I call to the IP of my ethernet card,
it doesn't work. Should it ought to work?

2.  Can you send UDP packets across the Internet to another host?  (This may

> No, I can't. I tried to send UDP packet to my Rackspace server from my PC
using python code. And also using nc. So far I remember the default TCP
packets worked, but when I tried to send UDP using -u, it didn't work.

> 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.

> I hope it was true. But isn't it too unlikely?
