No. Ipsec creates rules to join networks. Generally you
can’t route traffic between tunnels. <o:p></o:p></span></font></p>

Most managed switchs us a technique called spanning tree. A lot of
embedded devices will miss DHCP when because their boot up time is so fast that
the port is not alive before the switch determines that you do not have a loop
back condition. What is the correct way to solve this.<o:p></o:p></span></font></p>
<p class=MsoNormal style='margin-left:.25in'><font size=2 color=navy
face=Arial><span style='font-size:10.0pt;font-family:Arial;color:navy'>A.
In some switches they have a feature called port fast, turn this on ports that
have embedded devices. In some middle ground switches you have to
disable spanning tree on that port or even the complete switch.<o:p></o:p></span></font></p>

type of networking questions would you suggest to weed out interview candidates
during a 15 minute phone conversation? The emphasis would not be on any

firewalls, vpns, ipsec, ssl, dns, hubs, switches, routers, etc.</span></font><o:p></o:p></p>
