DMZ Building Practice

[Brad_MacQuarrie () maritimelife ca]

I have a question which may be more philosophy that engineering but here
goes:  What have folks most often embraced as the best practice in building
a DMZ'd infrastructure:  multiple, two-interface firewalls between DMZs or
a single firewall with mulitple interfaces forming the DMZs.  I realize
that cost likely owns the lion's share of this decision but other
considerations would be helpful as well.


Thanks
