You don't need to do any of that - if it's in a different VLAN, then
it's in a different network and the server will take care of things

subnets appropriate to the networks in use and it "will just work".
Think of VLANs as like having multiple non-connected switches and
NICs and you'll not be far wrong. In essense, VLANs simply allow the

WANTED: "Software CD ROM Kit" for Canon CLBP 360-PS printer (Canon
part no RH6-3612, or possibly RH6-3810, or RH6-3610 might do). I've a
