People,<div class="gmail_quote"><div><br></div><div>Please do excuse me if this is a FAQ.</div><div><br></div><div>I&#39;ve so far not worked out a way to implement IP authentication effectively. I have a number of gateways/end points/...etc. hitting the switch without registration and originating calls to a number of upstreams I have configured.</div>

<div><br></div><div>So far, everything is smooth and FREESwitch is legendary in every way. Over 10,000 simultaneous sessions at 120cps, on a dual-Xeon machine running CentOS and CPU usage is barely a blip.</div><div><br>
</div>
<div>My problem is authentication. I need a method to authenticate end points based only on their IP addresses. I am currently filtering access through the firewalls, but I would really like to delegate this task to FS in prep for an SBC setup I&#39;m working on. If I remove the firewall filters, then anyone is able to get in.</div>

<div><br></div><div>I could&#39;t workout precisely how ACLs work in FS from the WiKi and the documentation, and I haven&#39;t been able to make sense of how Digest functions either.</div><div><br></div><div>Can anyone shed some light on those two areas ? I would like to really get to the bottom of this and update the WiKi pages with the working setup once done.</div>
