<h1><a name="DealingwithNAT-Overview"></a>Overview</h1>
<p>NATs are an unavoidable complication for many systems. Asterisk SCF provides support for <a href="/wiki/pages/createpage.action?spaceKey=TOP&title=Enabling+ICE&linkCreation=true&fromPageId=19009568" class="createlink">Interactive Connectivity Establishment</a> (ICE) for RTP and <a href="/wiki/display/TOP/Glacier2" title="Glacier2">Glacier2</a> for managing access to Ice based services across a firewall.</p>

ICE is an acronym for Interactive Connectivity Establishment and Ice is the name of ZeroC's object oriented middleware product. We apologize for the inconvenience.</td></tr></table></div>
