SOLAR SYSTEM CONTROLLER WIFI FEED.

Question

I have a monitoring system on the controller of a thermal solar setup that collects data as conditions change throughout the day.  Locally I use one of my apple machines via airport to log on to the system by using an http numeric address.
I would like to stream that info through my iweb created site and haven't the foggiest notion how that can, or even if it can, be done.
i can dedicate one machine in range of the limited wireless signal to dedicate to this purpose.
Any thoughts?  Am I simply a lame-***?
Please advise.

Locally I use one of my apple machines via airport to log on to the system by using an http numeric address.
that establishes your solar controller has a web server running on your LAN/private network.
at the moment you can only see it inside your LAN. you need to do port mapping on your airport to make it visible to the outside world.
does the airport have access to the internet?  YES
first, you need a static ip address on the machine that runs the solar controller web server.
system preferences --> network --> airport --> advanced... --> tcp/ip --> configure ipv4 --> manually
ipv4 address: 10.0.1.200  --> the first three numbers must be same as your airport ip address
subnet mask: 255.255.255.0
router: 10.0.1.1 --> this is your airport ip address.
now the machine ip address is fixed and you can always access your solar controller with http://10.0.1.200
next, check your solar controller manual, find out which port the web server is using; typically is port 80.
see Tesserax's airport port mapping procedure here (section 2):
https://discussions.apple.com/thread/1878678?threadID=1878678
you need to map the airport to:
public ports tcp/udp: 80
private ip address: 10.0.1.200 --> this is ip address of your solar controller web server machine.
private ports tcp/udp: 80
once port mapping is done.
1) if you have static ip address from your isp.
you can verify port mapping by point a browser to this static ip address and you should see your solar controller.
2) if you have dynamic ip address from your isp and because dynamic ip address changes from time to time, then you should sign up with one of the services that resolves dynamic ip to a domain name. two of such services i can think of: dyndns.com and no-ip.com they both provide free services.
once you have the service set up and running on one of your machines (preferably on the same machine of your solar controller).
you can verify port mapping by point a browser to the domain name given by dyndsn.com or no-ip.com and you should see your solar controller.
then in your iweb project, you either link the static ip address or the given domain name using an iframe in an html snippet… search this forum for 'frame html snippet'
How do you do that QUOTE THING, unlike my copy/paste routine?
