The configuration I use allows only wanted traffic between two ID-1
radios:
You need a router with each ID-1 that can do NAT (network address
translation) AND simple port forwarding (or a "DMZ computer"
function).? I use an old Netgear WGT624v2 (which does both), and is
spec'd to take 12vDC but runs just fine (as do my other Netgear
switches and routers) from a RigRunner supplying 14.2vDC.
Say computer #1 is on the network with address
:
I configure router #1 to have a LAN (local) address of? 192.168.1.11
(these are examples, pick your own IP addresses in the same
network), and a WAN (remote) address of 10.0.0.21 (netmask
255.0.0.0).? The router then becomes a gateway to all 10.x.x.x
addresses.
?I configure computer #1 to route only 10.x.x.x/8 traffic to
192.168.1.11 (the router's LAN address)? There are a couple ways to
do this:
- Use the ROUTE command at the Windows command line to add
192.168.1.11 as a gateway to the 10.x.x.x/8 network.? Type just
"route" at the Windows command line to learn the settings (in
Windows 7, this even displays an example).? I think the correct
command in this case is "ROUTE ADD 10.0.0.0 MASK 255.0.0.0
192.168.1.11"
- Go into your Windows settings and accomplish the same thing
(this varies by version of Windows).
Connect computer #1 to a LAN port of router #1, and connect ID-1 #1
to the WAN port of router #1.
Now do exactly the same thing with computer/router/ID-1 #2, EXCEPT
give router #2 a WAN address of 10.0.0.22.
If you have computer/router/ID-1 #3, #4, etc on the RF network,
configure them similarly, giving each router a unique WAN address on
the 10.x.x.x network.
With the radios on and enabled for data transfer, from computer #1,
try to ping 10.0.0.22 (or from computer #2, try to ping 10.0.0.21).?
This needs to work before you go any further.? You may have to
enable WAN pings on the routers.
If the above works, you now have the basics of your network
functional, but you can't (yet) pass traffic between the two
computers.? To do that, you have to use the router's port forwarding
or "DMZ computer" capability.
Let's say that computer #2 has a web server (typically using port
80) that computer #1 needs to access.? You configure router #2 to
"port-forward" all WAN requests for port 80, to the address of
computer #2.? If your router has a "DMZ" function, it's even
easier:? you configure router #2 to set the "DMZ computer" to the
address of computer #2.? Now computer #1 should be able to access
the web server on computer #2, using IP address 10.0.0.22.
Using the "DMZ computer" function has both advantages as
disadvantages:? It makes ALL of computer #2 TCP/IP ports visible on
the radio network.? This helps if you want to do file sharing.
Note that all computers should address other computers on the RF
network by the remote computer's
router address of
10.x.x.x.
Note also that this is not the only way to do this, but it works for
me.? and it keeps the local network traffic at each site, off the
air.

A
switch can help out a little, but a router is suggested. But
even with the router, you still have the issues of other
applications hogging the channel.
I've heard it suggested that simply hooking the ID-1
to a network switch helps prevent a lot of network traffic from
hitting the airwaves. A hub that sends everything everywhere
would be a bad idea.
