Absolutely. I don't use ISA, and hence I have no need of a second NIC; I
think it merely complicates matters without providing any real security
addition.

Just make sure you have a decent firewall appliance. I personally like
SonicWALLs. I realize you're a nonprofit, but that doesn't mean your data
isn't worth protecting properly.

The firewall will do NAT (but not *just* NAT) so you use a private subnet
for your LAN, and port forwarding in the firewall to get the appropriate
public traffic to your LAN.


Here's some useful articles that will help:
Configuration of the UPnP router by the SBS 2003 CEICW wizard:
http://www.smallbizserver.net/tabid/266/articleType/ArticleView/articleId/79/Default.aspx

I don't recommend UPnP on a corporate network.....configure your devices
manually.

Network configuration - Two NICs, a static IP address, ISA, router:

As I said, I am out of my league concerning a single NIC. Maybe
others will weigh in on this.

Mike,

This is great information. I currently only have one NIC in my SBS
server with an IP of 192.168.1.6, and it sits behind my firewall
with all my other
machines. I have a static IP with my ISP, do I need another NIC on
my SBS server, or can I just use the one.

Thanks,
Mike

It should work fine. The CEICW wizard is a big help. There is
also some great resources at smallbizserver.net on how to do this.
Here's what I did:

Internal NIC: 192.168.16.2
External NIC: 192.168.1.10
Router: 192.168.1.1
On the router I forwarded port 25 to my server (192.168.1.10).
[There are also other ports you'll want; do a search on this NG for
threads that discuss it.]

On the external NIC > Properties, set the SUbnet Mask and Default
Gateway (should be your router IP), and your Preferred DNS server
(I have mine set
to the Internal NIC IP). Click on the Advanced tab and then WINS and
disable
NetBIOS.
On the internal NIC, leave the default gateway BLANK!!

On my router, I have a dynamic IP with the ISP. It's a very simple
router,
but the setup screens made it easy for this
"not-quite-a-bona-fide-techie".
I seem to remember setting the ISP's DNS server's in the setup, and
the IP
of the router, and it reached out and made the connection for me. Then
CEICW in SBS did the rest.
As a lesson learned, you might want to use a DNS server that is NOT
at the
ISP. I ahd some DNS problems and it turned out it was the DNS
servers at the ISP. Now I set 1 IP to the ISP and the other to
4.2.2.1 (a commonly used DNS server 'out there').

As always, keep asking questions. The people on this NG are really
good about helping those of us who are still learning or are
stumped. Lastly, I'm certainly no expert, so it would be nice to
get the opinion's of others
on this issue. Good luck!

Mike,
Thanks so much, still encouraged. I'm not exactly sure where to
go next.
I need to figure out how to get this setup and working. I believe
I have
exchange mailboxes for all my users, but I don't know exactly how
to make
the
connection with the ISP. Do I just open port 25 on my firewall and
point
it
to my SBS server?

I found docs on MS Exchange Server web site about migrating from
other flavors of Exchange or other mail programs, but not how to
make the proper
connection via our ISP.

My network is behind a Linksys Firewall, and my SBS Server has
192.168 IP
address, will this cause problems?

Thanks for your help!

100 GB is more than enough. We've been on Exchange about a year
and are
only up to 4.7 GB - and our staff saves EVERYTHING. Granted, we
only have 6
people, but that'd still only be about 30 GB for your 35 people. For
long
term storage/growth, 100 GB is probably good.

As for POP, I kept it for a bit as a backup. Once we felt
confortable, I
cut
it off. One thing I did, on the recommendation from others on
this NG,
was
get a mail backup. I use dyndns.org. Great company. The only
thing I've
got at the ISP is our website.

Let me know if you ahve other questions.

This is encouraging so far. I am running SBS 2003 Premium, and I
set
aside a
100G partition for Exchange, do you think that will be good
enough? Also,
do
you use the POP3 Connector to you ISP?

Thanks,

Mike

Hi,

I work for a small non-profit and we run SBS 2003 which has
Exchange
2003
installed. We currently are not using Exchange, our e-mail is
hosted
by
our
ISP. My boss wants to have outlook 2003 shared calendaring
functionality,
and I told him that was only available if we run Exchange. He's
concerned
about us hosting our own e-mail. I'm the only IT guy (35
employees
in
the
organization) and he is worried about how much time it would
take to
administer Exchange.

What would you suggest? I guess there are some 3rd party tools
for
sharing
Outlook calendars, but I see additional benefits with Exchange
(OWA,
etc).
I
also posted this on the Exchange Server newsgroup too, but
figured
this
might
be the better place.

Thanks,

Mike
