Icecast - Nov 2009 - Running the Omnia A/XE encoder and Icecast on the same machine

Can someone tell me what IP address I should use to make this work?  I have
tried the normal 127.0.0.1 loopback and also the IP address of the machine
with no luck.  The A/XE software allows me to output to three types of
servers.  Shoutcast, Http, and Windows Media server.  I have tried sending
to all three even though I know using the shoutcast setting should work.
You can see the software at

would be greatly appreciated.
Thanks in advance
