Can the server successfully resolve names? Does its default route work outbound? Can you grab websites using curl or wget on that server? A network unreachable error really seems unrelated to kolab or any server system at all. Try narrowing down the issue. Perhaps dig <a href="http://apple.com" class="">apple.com</a> to see if you get an IP etc..</div><div><br class=""></div><div>— </div><div>Nathanael</div></body></html>
