(they would want to make the problem SOUND difficult afterall) -Jim H ---- Jim Howard Sr Network Engineer Lyceum Internet jhoward@lyceum.com <A HREF="http://www.lyceum.com/">http://www.lyceum.com/</A> 404.248.1733 My PGP Public Key: <A HREF="http://www.lyceum.com/~jhoward/pgp-key.txt">http://www.lyceum.com/~jhoward/pgp-key.txt</A> Fingerprint: 7E8B E2BA 1314 2535 CB08 CFF9 119B 7CD3 2488 954D ++ Ascend Users Mailing List ++ To unsubscribe: send unsubscribe to ascend-users-request@bungi.com To get FAQ'd: <<A HREF="http://www.nealis.net/ascend/faq">http://www.nealis.net/ascend/faq</A>> </PRE> <!--X-MsgBody-End--> <!--X-Follow-Ups--> <!--X-Follow-Ups-End--> <!--X-References--> <!--X-References-End--> <!--X-BotPNI--> <HR> <UL> <LI>Prev by Date: <STRONG><A HREF="msg08363.html">Re: (ASCEND) Getting Customer Downstream Speeds</A></STRONG> </LI> <LI>Next by Date: <STRONG><A HREF="msg08361.html">Re: (ASCEND) Max4000 & WINS</A></STRONG> </LI> <LI>Prev by thread: <STRONG><A HREF="msg08348.html">Re: (ASCEND) MAX ARP cache and reconnect problem</A></STRONG> </LI> <LI>Next by thread: <STRONG><A HREF="msg08350.html">(ASCEND) NAT routing to a Network</A></STRONG> </LI> <LI>Index(es): <UL> <LI><A HREF="mail21.html#08362"><STRONG>Main</STRONG></A></LI> <LI><A HREF="thrd151.html#08362"><STRONG>Thread</STRONG></A></LI> </UL> </LI> </UL> <!--X-BotPNI-End--> <!--X-User-Footer--> <!--X-User-Footer-End--> </BODY> </HTML>
