Are you sure it's wise to even consider LXC here?

And can one PC really keep up with 20Gb/sec of Ethernet traffic? i.e. How 
do you know the bottleneck here won't be the PC rather than the firewall 
appliance... I'd seriously consider using 2 PCs - firstly back to back, 
then with the firewall in-between...
