************************************************
Dan, thx...yes, I only have one ethernet switch, but i believe it is
capable of handling virtual LANs...should I build VLANS on the switch to
separate the ethernet segments?  I am running 8 pcs and simulating various
things (VPNS, firewalls, etc) .It is a 24-port 3com 3300 switch.  I just
got my gig-e nic running now as well, so will experiment with routing
traffic through it. thoughts?
