Just wanted to thank everyone for their help. I&#39;ve gotten the issue resolved.<br><br>Apparently Freeradius was working 100%, what wasn&#39;t working, however, was my Cisco routing. We had our network worked on several weeks back, and all seemed to be working ok, but it never dawned on me to check if my Cisco AS5400 could ping out to the freeradius server or not (it couldn&#39;t).<br>
<br>So after talking with our Cisco guy and straightening the issue out, all works well.<br><br>Thanks so much for your help!<br><br>-Randall<br><br><div class="gmail_quote">On Mon, Mar 29, 2010 at 7:54 PM, Tim Sylvester <span dir="ltr">&lt;<a href="mailto:tim.sylvester@networkradius.com">tim.sylvester@networkradius.com</a>&gt;</span> wrote:<br>

<p class="MsoNormal"><span style="font-size: 11pt; color: rgb(31, 73, 125);">My guess is that there is a firewall in front of your Linux
server running FreeRADIUS. Rackspace typically puts a Cisco ASA firewall in
front of a customer’s Linux server. When you ran the nc test, was the system
that you ran nc from on the same network with the Linux server running
FreeRADIUS? They both might have been behind the same firewall. Check with Rackspace
to see if there is a Cisco Firewall in front of your Linux server.</span></p>
