</HEAD>
<BODY>
<P><FONT SIZE=2>The issues being raised by Mr. MacLauchlan revolve around the NAT functionality of the Contivity Firewall. Nortel Networks does not see this as a Firewall issue and has received no feedback from customers on stability issues surrounding the Firewall functionality. The recommendation NOT USE the Firewall based on the NAT issues is misplaced.</FONT></P>
<P><FONT SIZE=2>Nortel Networks has addressed the NAT stability issue with Sprint directly and a patch was provided to SPRINT and accepted by SPRINT on 4/5/01. The patch for this problem was included in our 3.6 code released on 4/10/01.</FONT></P>
<P><FONT SIZE=2>If you are currently running v03_50.44 and are not using the NAT functionality you WILL NOT encounter any stability issues.</FONT></P>
<P><FONT SIZE=2>If you have any questions about this issue please contact Nortel Networks technical support or your local account team and upgrade to software version 3.6</FONT></P>
<P><FONT SIZE=2>Currently SPRINT is re-selling this solution and has accepted all fixes that have been put in place to address the NAT issue. We have seen very good response to the firewall by the number of sales being placed through SPRINT and have no outstanding issues with any customers surrounding the Contivity Firewall functionality.</FONT></P>

<P><FONT SIZE=2>Upgrade to version 2.6 then upgrade again to 3.5.</FONT>
</P>
<P><FONT SIZE=2>Personal recommendation DO NOT USE THE NORTEL FIREWALL. There will be</FONT>
<BR><FONT SIZE=2>a patched version of the firewall code, hopefully very soon. It is</FONT>
<BR><FONT SIZE=2>my understanding the box can become unstable with the 3.5 firewall</FONT>
<BR><FONT SIZE=2>running.</FONT>
</P>
<P><FONT SIZE=2>Overall the 3.5 software appears to be just as stable as the 2.5x</FONT>
<BR><FONT SIZE=2>software and that is good news.</FONT>
