RE: Port Forwarding not working

Hi DAS,

Thank you for posting in SBS newsgroup.

From your description, do you mean you want to configure port forward to an
internal Windows XP from your SBS server with 2 NICs?

To narrow down the problem, would you please help me confirm if you have
ISA installed on SBS? If you do not have ISA, you can configure RRAS to do
port forwarding. With ISA, you can use ''server publishing''.

For RRAS, you can refer to the following steps:

1. Open RRAS console. Navigate to 'IP Routing'\'NAT/Basic Firewall'. Open
the properties of the ''Network Connection'' in the right panel.
2. Click 'Services and Ports'. Click 'Add' button and then add the desired
service.

For ISA, please refer to the following KB article:

I appreciate your time and look forward to hearing from you.

| I'm trying to set up SBS to port forward a couple of ports and it just
isn't
| working and I need help.
|
| Here's what I have and what I've already tried...
|
| We have web cams in our building that web broadcast on our website. The
| webcams are connected to a Windows XP machine and the broadcast software
uses
| IIS that's built into Windows XP. (So basically the web cam server is
also a
| web server too.)
|
| I recently installed Windows SBS 2003 on our file server and I'm using it
as
| our NAT / Firewall (using two NICs). We have business class DSL with a
static
| IP (and no ports blocked by our ISP).
|
| 1. I've assigned a static (private) IP to the web cam server using
| "Reservations" in SBS DHCP (192.168.0.111). I also read (and tried) that
you
| can set the IP manually on the client computer and then exclude that IP
in
| "Address Assignment" but that didn't help with my original port
forwarding
| problem.
|
| 2. On the external NIC, under "Services and Ports" I've added port 8080
and
| forwarded it to 192.168.0.111. I want to use a different port because I
want
| to reserve port 80 for SBS' own IIS so the (built in) company website is
| still assessable on the internet.
|
| 3. On the webcam server I set IIS to listen on port 8080.
|
| Here the problem... none of that works...
|
| a. If I type in our external IP address I get the Windows SBS 2003
Welcome
| page (which is good).
|
| b. But if I type in our external IP address with port 8080
| (xx.xxx.xx.xx:8080) I get a "can't connect" error (which is bad).
|
| c. If I'm on the network and I type in the private IP of the webcam
server
| with port 8080 (192.168.0.111:8080) I get the webcam's home page (which
is
| good also).
|
| I just can't seem to get SBS to allow port 8080 to tunnel through to our
web
| cam server. I also know it should work because before I started using SBS
| 2003 as our NAT/Firewall we were using a NetGear router that I had port
| forwarding setup and it all work perfectly. But now I can't seem to get
SBS
| 2003 to do what I could do in the NetGear router.
|
| Does anyone have an idea of what I'm doing wrong?
