RE : [midcom] More on new work item

["Joel Tran" <joel.tran at USherbrooke.ca>]

Jonathan Rosenberg, you raised a good point.

There are however some ISPs that are deploying NAT/Firewall (i.e. China,
Europe, Africa). In such case, DHCP might be useful. The ISP might do some
load balancing. Thus, DHCP method will provide a mean for the ISP to
configure dynamically third-end party devices. As for the security
information, this might be entered by the user to the third-end party device
(ex: same id/password as for the ADSL authentication).
