Re: How do I configure SBS 2003 as a DHCP server?

The SpeedStream 6520 is indeed capable of handling PPPoE. However, if I need
to disable it's DHCP functionality, I have to disable all it's extra
intelligence (at least that's why my ISP told me) including it's PPPoE
capability. Therefore, I configured SBS as my PPPoE conduit. When you run
CEICW, there's an option to do this. So, the PPPoE adapter I have is on SBS
as a software component. At this time, SBS authenticates against my ISP's
servers for PPPoE.

Merv, please see Cris' post below and let me know if there's anything else I
need to do.

Thanks.

Where did the need for a "PPPoE adapter" come from (and where is it
installed)? Your SpeedStream 6520 should be able to handle PPPOE.

Hi Merv:

I can now see that my external NIC does indeed have a private IP address.
It's my PPPoE adapter -which has been newly added to my configuration,
since
I had to enter my username/password for the PPPoE connection somewhere
other
than the modem - that has the public and static IP address. I had to run
CEICW again after disabling the DHCP server on the modem which is a
Siemens
SpeedStream 6520.

Here's the new output of ipconfig /all, which was executed on SBS,
encapsulated in a C-style comment:

I thought you had a router on your network. Your IP config (from a
previous
post) for the server indicated that you have 2 NICS and that the external
one was assigned a static private IP address (192.168.2.11). Generally,
this indicates that the modem is really a "modem-router". What
make/model
"modem" do you have?

Merv:

Are you sure that you want me to assign a static and private IP address
to
the external NIC? How will hosts on the Internet find my server?
Remember,
I
connect to the Internet using the external NIC.

As of now, I have disabled the DHCP server on my modem. And the
external
NIC
is set to "Obtain an IP Address Automatically". Isn't this the right
way
to
do this?

Please clarify.

Thanks.

Hi JJ,

Here's a diagram of how your network should be physcially set up:

Two Nics, a dynamic IP address, ISA and a router
http://www.smallbizserver.net/Default.aspx?tabid=266&articleType=ArticleView&articleId=74

Your ipconfig from an earlier posts shows that the external SBS NIC
has
been a assigned a dynamic IP from your router's DHCP service. After
you
have the physical network set up correctly, from the SBS server access
the
web interface of the router (192.168.2.1) and turn off DHCP on the
router.
Then from the SBS server:

My Network Places | Properties | External NIC | Properties | Internet
Protocol (TCP/IP) | Properties | assign a (static) IP of 192.168.2.11
and
enter 192.168.16.2 as the (static) Preferred DNS server.

Now, check the SBS server NIC bindings:
-----------------------------------------------------------------
Right click My Network Places...Properties. Highlight the Internal
NIC.
Then
select Advanced...Advanced Settings from the top menu for that window.

The Internal NIC should be displayed first followed by the External
NIC.
If
not, move the Internal NIC to the top of the list.
The Internal NIC should have File and Printer Sharing bound (check
marked)
to the TCP/IP Protocol.
The Internal NIC should have Client for Microsoft Networks bound
(check
marked) to the TCP/IP Protocol.
The External NIC should be bound to TCP/IP only (no other protocols or
services).
-----------------------------------------------------------------

After everything is set up properly, re-run CEICW

CEICW Walkthrough
http://www.sbs-rocks.com/sbs2k3/sbs2k3-n2.htm

On the Firewall screen, make sure you enable the firewall, select the
services you want, create the Web Server Certificate and finish the
rest
of
CEICW.

At that point, the SBS server should be handling DHCP for your LAN.

Also, make sure that the firewall client of ISA has been installed on
each
workstation (but not on the server itself).

The kind of networking people I get here would introduce
spyware/trojans/rootkits into my PCs to control them so that they
can
get
more business from me. So, that's not an option.

The DSL router that I'm using does have a static and public IP
address
on
it's WAN interface. The 192.168.2.1 address is where it hosts an
embedded
HTTP server for administering the router. The DHCP server on the
router
assigns the static IP address 192.168.16.2 to my SBS PC. I would
like
to
turn
off the DHCP server on the router as per your suggestion. However,
my
ISA
Server is blocking access to 192.168.2.1 - the router's HTTP server.
What
kind of rules should I create on my ISA Server to allow this?

Thanks.

Sorry but this is getting more confusing all the time. The SBS

DHCP.
Is
your DSL router receiving a public IP on its WAN interface? I'm not
sure
how
it can be using both a 192.168.16.x and 192.168.2.x range?

I think it may be time to bring in outside help by someone
knowledgeable
about SBS and general networking to help you sort this out.

The DSL modem has to have DHCP running. SBS has to have an IP
