Setting up RSS to stream data

Setting up RadioSky Spectrograph (RSS) Software to Stream Data
There are several configurations of Modems and Routers – they may be separate boxes, or both
located in a single box. They reside between the Wide Area Network (WAN), often called the
Internet, and the Local area Network (LAN) – your home computers and other devices. This
writeup will focus on separate units for the Router and Modem (Fig 1) but the principles apply to
whatever configuration you may have. In any case you will need to access both the router and
modem thru the web browser interface in your computer.

The process of getting your FSX up and running and serving is almost as easy as A, B, C
A. Establish a static IP address on the RSS computer
B. Set router with the RSS computer static IP address and RSS program port number.
C. Set the modem to enable the DMZ feature for the router (this step may not be needed)
How many IP addresses do my modem and router have?
More than you probably think. Each device has two that we are concerned with. The router has
a LAN side IP Address and a modem side IP address while the modem has a router side and a
WAN side IP.
Static or Dynamic IP address for RSS?
IP addresses can be either static or dynamic. Dynamic IP addresses can change frequently.
To stream data from the RSS computer you need to establish a static IP address for that computer
and then set up your router so that it has the correct LAN side IP address for your RSS computer
and also the correct port number.
The procedures for doing this are similar but not identical for different Windows operating
systems. Two examples are given – one for Windows XP, the other for Windows 10.
Can I have some computers with Static and some with Dynamic IP addresses together on
the same LAN?
If you have several computers on your LAN it will not cause a problem to configure one (or
more) with a static IP address while the other computers have a dynamic IP address. The other
computers will still be serviced properly by the DHCP server in your router. The DHCP
(Dynamic Host Configuration Protocol) server hands out dynamic IP addresses of its choosing to
the various devices on the LAN. The router will accept a static IP address for one or more
devices. For RSS to operate properly we need to assign a static IP to the RSS computer and in
addition set up the Router with the port number associated with RSS (also called port
forwarding).
How can I talk to my router?
From your computer, you need to access your router settings. Many routers use a LAN side IP
address of 192.168.001.001, so this is the number you would type into your browser (Fig 2).
Fig 2
Most likely your router will ask you to log in with a username and password. Consult your
owner’s manual if necessary to complete this step. Once you are logged in your router should
respond with, depending on make and model, a window that will permit you to make changes to
the router itself.

The range of dynamic IP addresses
As a general guideline you want static IP addresses to lie outside the range of dynamic IP
addresses being used by the DHCP server. This means you should determine (or set) the range
of dynamic IP addresses in use by the DHCP server in the router and then make sure that the
static IP address you choose for the RSS computer is not inside that range.
Write down the range of dynamic IP addresses and the static IP address you choose. You will
need the static IP address later in this set-up.
Caveat: Avoid using a static IP address ending in .0 or .255 (most often not valid) and avoid
using a static IP ending in .1 or .254 (commonly already in use by your router or gateway).
Note: IP addresses do not need leading zeroes in the “dotted quads.” That is, 192.168.001.001 is
equivalent to 192.168.1.1.

End ______ . ______.______ . ______
Static IP ______ . ______.______ . ______
OK – now you have selected it you are ready to set up the static IP address on the RSS computer.
The procedures for doing this are similar but not identical for different Windows operating
systems. Two examples are given – one for Windows XP, the other for Windows 10.
For Windows XP go to pages 4 & 5.
For Windows 10 go to pages 6-8.

A. (Windows XP), Establish a Fixed IP Address for the RSS Computer
Go to: Control Panel>Network Connections>Properties>Internet Properties (TCP/IP)
In the Local Area Connections Properties dialog box (Fig 3) select Internet Protocol (TCP/IP)
and then Properties.
In the Internet Protocol Version 4 (TCP/IP) Properites window Select “Use the following IP
address” and enter your chosen static IP address (Fig 3).
Fig 3
4
The Subnet mask should fill automatically.
Enter your router LAN side router IP address (probably 192.168.001.001) for the Default
gateway.
Select “Use the following DNS server addresses” and again enter your router LAN side IP address as the Preferred DNS server Skip to Section B, page 9.
5
A. (Windows 10), Establish a Fixed IP Address for the RSS Computer
In the Control Panel find the Network feature (Fig 4). Navigate your way to the “Adapter
Settings” (the exact path may vary depending on the version of Win OS you are running)..
Fig 4
6
Locate the Ethernet Properties (Fig 5) dialogue box, and right click Internet Protocol
(TCP/IP). Again, depending on what WinOS you’re running, the wording might be slightly
different, but select the one that says TCP/IP. In Win 10 and possibly Win 8, do NOT select the
one that has Internet Protocol Version 6 (TCP/IP). Select Internet Protocol Version 4
(TCP/IP) and press the Properties button.
Fig 5
Fig 6
In the Internet Protocol Version 4 (TCP/IP) Properties dialog box (Fig 6) , you will need to check
the Use the following IP address. When you do, the grayed out boxes below it will become
active and you will be able to insert numbers.
7
Fig 7
Enter the Static IP address you selected previously. (in this example 192.168.001.100 as seen in
Fig 7.
Select “Use the following IP address” and enter your chosen IP address.
The Subnet mask should fill automatically.
Enter your router IP address (probably 192.168.001.001) for the Default gateway.
Select “Use the following DNS server addresses” and again enter your router LAN side IP
address as the Preferred DNS server
Click OK and the window will close and you’ll be back to the Ethernet Properties window.
Close that window. You’re done with this part. Your RSS computer static IP address is set.
8
B. Set Router With RSS Computer IP Address and RSS Program Port Number. By default, RSS is set to stream data on port 3627. That’s the port number you will enter in
the router along with the associated static IP address.
Log into your router using your computer browser and navigate to the window called Port
Range Forwarding. An example Linksys Port window is shown below (Fig 9). Various
models will look different. Sometimes it will just be called Port Forwarding.

Fig 9
In this example, for the FSX-8S Spectrograph, the name has been typed in so settings are
recognized as being associated with that spectrograph. For this make and model Linksys router,
it’s necessary to select Edit, then enter the information. Start – End Port will be the port RSS
is set up for. In this case, 3627, entered as 3627-3267.. Protocol will be Both. This might vary
with the router. If there are two selections there rather than the word Both, select them both.
Enter the IP Address of your RSS computer. Whatever IP Address you entered in the
Internet Protocol box earlier, you enter here. If you entered 192.168.001.100 in that box you
will enter 192.168.001.100 here. (In this example, the user entered 192.168.001.105.) You will
need to Enable this setting, telling the router that this port is now open for your RSS computer.
When you are done, click Apply.
That’s it. Back your way out of the router settings. Some have a Sign Off or some other way to
X out of the router dialogue box.
C. Set Modem to enable its DMZ feature for the router. (optional – if RSS doesn’t serve properly after you finish step B then try this also) By default, most modems do not have the DMZ (demilitarized zone) feature enabled. You want
to enable this feature in the modem for the modem side IP address of the router.
Log into the modem’s control interface. (check the modem manual for how to do it)
Find the IP address of the router as seen by the modem (this will NOT be the same as the LAN
side router IP address). Write this down – you will need it shortly.
10
MODEM side IP address in the router ______ . ______.______ . ______ In the example (Fig 10) you see a Windstream modem interface.
Under Device Info, DMZ Host is listed under the heading of NAT.
Select DMZ Host. (What the heck is a host? In this context it is the router.)
Enter the router’s modem side IP address into
the DMZ Host IP Address box and hit Apply
Fig 10. In this example, the router has an IP address of 192.168.254.2 as seen by the modem. Enabling the DMZ for this IP address forces the modem to pass all packets unfiltered to the router, which is exactly what we want. At this point you should be able to begin streaming data with RSS.
