Q: Jetty - unable to connect to WFS/WMS from outside.

To connect to Jetty from other than the 'localhost' URL, you must edit your jetty.xml file located under documents/ in the source distribution of GeoServer (the SVN or .src versions). In jetty.xml add:
<Set name="Host">###.###.###.###</Set>
where the hashes (#) are the IP address you want.
