I assume that translates to "I added another NIC and switch for the internal networks".

More complicated, but also probably more expensive - depends what switch you buy (and other factors). IME, by the time you are up to the level of manageability that gives you VLANs on the switch, you are paying more for that level functionality than you'd save in the cost of the NIC.

I was actually thinking of saving in terms of the switch port. Less ports needed should equal to less switch required, thus cheaper :)

Then again, this is assuming Fritz already has a VLAN-capable switch (a 24-portÂTP-LINK TL-SL5428E should cost less than $200).

Adds a lot of options though - I've a VM with 6 virtual NICs plus tunnel, 6in4 tunnel, and PPPoE interfaces acting as a router at work with VLANs to get the networks to the right place :)

Cool :)
