The setup I have been running for a while is a 1 nic card setup with 
squid. I have a sonic wall at this point and still use an external DHCP 
for addressing. I use the sonic wall to forward to the DMZ to port 3128. 
All web traffic is re-routed to the squid and back again (transparent). 
I have forwarded for headers turned on in squid so that when people 
override the bess filter, it is only for the machine they are on, not 
the whole network. I had to work with MSLN on the forwarded for headers 
(provider), they just needed to allow them. I'm currently incorporating 
dansguardian into the setup. I would like to get dhcrelay working and 
can the sonic wall altogether, or swap the whole network (1024 subnet) 
over to it's own DHCP
