Re: Optimizing CentOS for gigabit firewall

I'd argue handling it at the layer 3 level to be preferable than splitting every customer into their own vlan.

If you split into vlans like that, if you have single-box customers, you'll have to have subnet boundaries for every /30...

OTOH, vlan isolation for customers is pretty much the norm, as long as you've got the IP's to waste, why not..

Or perhaps use a VLAN trunk to the switch with the devices you want to isolate
on different VLANs.  This gives you a different interface/subnet per VLAN for
more natural control.
