Hello,

        I have a configuration question.  My current linux firewall has three
NICs, one for the connection to the ISP and two for internal subnets. 
We are changing from an ISP which provided a class C block of addresses
to an ISP which will provide only 4.  I am planning on masquerading the
addresses on the two subnets but I want traffic for the real IP
addresses to pass through the firewall as well.  Will I need a fourth
NIC in order to network the other ISP provided addresses?  The other
addresses will be for a mail server, DNS, and webserver.  Any pointers
appreciated.
