Binh: I would like to correct the notion that the HUB gets IP addresses.
The NICs do. I don't know from LEAF point of view, but it would be
perfectly acceptable (I believe) that the 2 NICs in the one machine,
connected to the HUB, will each be assigned an IP address.
Our cable ISP will automatically assign 3 IP addresses without a call.
Extra IPs get billed.
Can I ask why you would want two external IP addresses for your router? If
you just want to share internet you only need one. If you want each
workstation inside to have an external IP, you could have two router boxes
but I.M.H.O that would just be a waste of hardware. You could just run a
software firewall on the two workstations.

Hi,
The ISP technician showed up but just upgraded the TV portion. He told us
to
call tech-support to get 2 IPs, so I think there is no need to have a new
cable modem. I did not contact them yet as I am not sure if we can hook up
both 2 IPs to 2 NICs on the router.
A friend with ADSL told me that you need a hub, the modem goes to the
uplink-port, then 2 of the other ports of the hub will be the 2 different
IPs. You could connect 2 computers into those to work.
Suppose that's the same for the cable modem, if I connect them to 2 NICs in
the router, would they work and how can I modify the DHCP client.
Charles, you mentioned something about the public DMZ network. Could you
explain me a little bit more so I can see if it is worth to have 2 IPs or
not.
----- from the network.txt help ----
Route packets to a DMZ network. This is a fairly advanced configuration.
Use
this setup if you have registered a block of public IP addresses, and your
ISP
is willing to route packets for this public space to your LRP box...

The questions you ask are unanswerable as posed. You need to tell us:
1. What physical devices is the ISP providing to you to handle the two
addresses? For example, are you getting 2 cable modems, or are you still
using a single cable modem provided by the ISP?
2. How are the two dynamic IP addresses actually assigned? Since you say
"cable ISP", I'm guessing DHCP, but we need to know what your ISP has
actually told you about this. (I don't actually know how it is possible to
assign 2 DHCP addresses to the same cable modem line, but perhaps someone
else has seen this implemented.) It probably told you how to connect 2
Windows computers, for example; in summary form, what procedure did it
describe?
3. Which LEAF variant are you using? With what physical and logical
interfaces?
5. What do you mean by "control both of them"? How do you want to use the 2
addresses?
