I am aware of that. But as I said it depends on your particular needs in 
*concurrent* traffic. Although it cannot sustain simultaneous Gigabit 
debits on all interfaces, i can sustain Gigabit bursts that are not 
simultaneous, as is often the case.

I have found that such a solution is perfectly capable when isolating a 
LAN, or several LANs,  from a WAN, for example.
