Well, i tried the IP address of my aquacontroler & it didn't work. I also did the IP check as you suggested and that address didn't work either? I have a wireless router for the house. The APEX is hard wired to the wireless router. does that have anything to do with it?
I am terrible at trying to explain things but I will try
when you go to IPchicken that is your external IP
that is what the internet sees you "house" or "home Network" as.
think of your "house" as a little internet. you have your own IP address assignements. it might help if you think of IP addresses af phone #s. if ou have 7 diget phone numbers you can only have so many until you run out, right? same with IP addresses. so there is a way to seperate the internet "WAN" (wide area network) and your house network "LAN" "local area network" still with me?
so you (anyone) goes to the store and buys a wireless or standard router. depending on brand the odds are you router that you bought is going to be IP of 192.168.1.1.
so now there are millions of people with this same address. But that is ok because that is on your LAN. so your Apex is I think IP 192.168.1.50 or 192.168.0.50. Again it depends on the brand of router you have. but how do you tell your phone to go to that internal address when all you have is an external IP? we will pretend your external IP when you go to IPchicken.com is 68.75.91.26. you remote into your router by going to internet explorer(the icon you use for surfing the net) in the addres bar type your default gateway. to find this click on start, run, type CMD, hit enter. then type IPCONFIG. it should be something similar to 192.168.1.1. so you type that into your address bar and that will get you into your router. there should be a section on port forwarding. it is also sometimes under "gaming".
so now you forward port 80, what ever you want it to be to IP 192.168.1.50, or the IP of your Apex. Some routers have a start and finish port. you will know what I mean if you see it. just put 8080 in both fields. Really all you are doing is telling the router that if a request comes in trying to go to 68.75.91.26:80, direct it to the internal address of 192.168.1.50! CLEAR AS MUD!
if you are still lost let me know what brand and model of router you have and I will try and be more specific. this is not simple stuff so don't feel bad.
