Re: Share Internet Connection with 2 SBS Same Router

A simple NAT router attached to the DMZ port would be good. I'm not going to
look at the specs for the sonic but you might need to check how this DMZ
port works, does it provide a 2nd WAN IP or does it operate a 2nd NAT'd
subnet? If it provides a 2nd NAT'd subnet you will have problems accessing
the test network from 'outside' because the ports on the external IP are
bypassing the DMZ to get to SBS on what the router refers to as LAN.

Yes, you could attach it to the DMZ. The DMZ should be "fairly" safe (at
least as a test bed) since your SBS 2008 network would have the Windows
2008 firewall plus a NAT router in front of it. You might also be able to
attach the cheap router to a port on the CISCO switch and then manually
adjust the port forwarding inteh Sonicwall as necessary for testing.

The SonicWall is a Pro 280. It is an older product now discontinued. In
any
case it only has a WAN, LAN and DMZ port. The WAN is going to our ISP,
the
LAN goes to our Cisco switch. All the clients and the SBS 2003 server
attach
to that switch.

Can I attach the cheap router to the DMZ? Although that is not safe...

One approach...

Attach a cheap router to the network: connect an Ethernet cable from a
free
port on the Sonicwall to the WAN port on the cheap router. Set WAN side
of
cheap router to a static IP address in the same range as the Sonicwall.
Then attach the SBS 2008 NIC and the workstation NIC to free ports on
the
cheap router. Set forwarding for required ports in the cheap router's
web
interface.

Problem... port forwarding from Sonciwall can only go to a single NIC.
Some port numbers can be changed. Some cannot. So in general, ports
443,
1723 and 25 can only be forwarded to either the cheap router static IP
OR
forwarded to the current SBS 2003 NIC (I assume you have an SBS 2003
setup
with a single NIC). You'll need to manually adjust the port forwarding
on
the Sonicwall as necessary to test the SBS 2008 network.

We currently have a working SBS 2003 domain. In a few weeks we are
going
to
be moving to SBS 2008. I am doing a learning dry run install of SBS
2008
right now on a extra server we are not currently using to make myself
comfortable with the install and to test some of the features. My
problem
is
I have only one internet connection. We have a T1 coming in to a
sonicwall
router/firewall that acts as our gateway. I cannot connect the SBS
2008
server to this because it then sees the SBS 2003 server. In order to
complete
the installation and test SBS 2008 I want to setup a separate network
consisting of the SBS 2008 server and one client, but I need to
connect to
the net through the current gateway in order to do this. Is there a
way to
keep these two networks separate but share the same net connection and
gateway? If so, how can it be done?

I have extra switches and routers that I can use.

Thanks in advance.
