there is no routing between the networks being done - i have a private
lan for management traffic, and a public lan for dns/www traffic.  each
vlan has it's own interface on the router (yes, the topology was really
as simple as my diagram - sad isn't it?)

thanks

"Walk with me through the Universe,
 And along the way see how all of us are Connected.
 Feast the eyes of your Soul,
 On the Love that abounds.
 In all places at once, seemingly endless,
 Like your own existence."
