Sorry, I see the confusion.
In LibraryServer.config, specify "ereader" for the "protocol" setting (this is how it is set by default).
Open ereader, add books, and go to another site as you did. The address will be
http://192.168.0.1:9033 in your case. This will launch Safari and the site should come up.
Where the "ereader://" protocol specified in LibraryServer.config comes into play is for the links to your books. The ereader:// protocol tells the iPod/iPhone to (re)launch eReader to download the book. You won't have to do anything special here, just navigate the site to the book you want to download and click.
For those using Stanza, you would specify "http" in the protocol setting in LibraryServer.config. In either case, this tells the server as it builds the HTML page that is browsed how to code the links to your books.
Let me know if this isn't clear.
