No, that is not the case. My firewall address is a public address and
not a private one. My firewall gateway address is also a public address
and has nothing whatsoever to do with the CM DHCP server address. My
firewall's IP address, along with the default gateway are on the same
(vast public) network of my provider, BUT this network is not part of
the CM's IP address. Does that make sense?
Here by "firewall" I mean the machine which is directly connected to the
CM and uses it to obtain the DHCP lease (for that public IP address). On
that same machine I also have 6 other interfaces - all internal -
through which I route traffic.
