<div class=Section1>
<p class=MsoNormal>I am trying to understand best practices for server
placement from a firewall perspective:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>There are two layers of firewalls, the Web tier which is
facing the public. The App tier is behind the firewall. The App
Tier cannot instantiate a connection to the web tier for security
reasons. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Is the best practice to have a federation of servers such
that the Web tier XMPP server is facing outward and automatically connects to
an XMPP server sitting on the App tier so messaging can occur with all clients
inside and outside the firewall?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I don’t think I have seen standard docs on how to
place Federation servers with respect to firewalls, etc. Any comments
would be greatly appreciated.<o:p></o:p></p>
