Crestron, Controling environment, video & audio
Ok, this is like a riddle...and very complex to ask, so please bear with me! I am sitting in a "smart" house (which ain't so smart right now). Actually, my client has 2 smart houses controlled by CRESTRON systems. These systems allow you to remotely control the climate, lights, video and volume in each house. Up until about a month ago, everything is working fine. Here is what has happened since then.
1. Sitting in house A on a wired network using AT&T DSL and a 2wire modem, the client is unable to connect to "smart" house B. I can surf the internet on the computer, nothing has changed in house B, as a matter of fact I can still connect to house B from any other network outside of house A. In addition, since he uses a docked laptop, I have moved that out of house A and connected to house B using the same computer that couldn't connect using the network in house A. In addition, none of the other computers in house A can connect to house B either hard wired or wireless. Oh, at this point I should say, that sitting in house A, I CAN connect to the Crestron in house A using public IP address with port 8080 (ie, by typing 62.1.2.3:8080 while sitting in house A, I can connect to the Crestron in house A)...obviously the IP is hypothetical to protect the innocent. So, sitting IN house A, I can connect to House A using a public IP, but I can't connect to House B. Outside of this network, on the SAME computer, I can reach House A or B from anywhere.
So, being the genius I am, and after putting up with AT&T on the phone (which is like scratching nails on a chalkboard), they decided it was a modem issue and sent me a new (refurbished) 2 wire modem. The old one was probably 7 years old, the one the sent me was a super duper new model that was gonna solve all my problems.
At this point I should also say that I carefully examined the set up of the old modem to make sure I correctly opened the ports to allow connectivity to Smart House A where the modem was being installed. The interface on both modems is virtually identical. There are 3 ports that need to be opened in order to hit the Crestron, which I opened on the new modem.
After installing the new modem, and opening the 3 ports nothing changed as far as connecting from House A (with the new modem) to House B. (Still not able to connect) And now I have an added problem. Sitting in house A, I am UNABLE to connect to the Crestron in House A using the public IP (62.1.2.3:8080). However, by using the private IP inside the network (192.1.2.3:8080) I can connect no problem. So now, from INSIDE the network, I cannot connect to EITHER house using their public IP addresses (Obviously, each house has a unique IP). But from OUTSIDE this network, I can connect to both.
Internet explorer times out, I get a DNS frame error that quickly flashes in the status bar before I get the standard "page could not be found"
I rebooted the Crestron in order for the NEW DSL modem to find it. The Crestron has a static IP.
I think I have included everything. I would sure appreciate any comments, suggestions, etc. you may have. These smart houses have kind of made me feel very stupid!
can you ping either public IP? what does a tracert to each public ip produce? what results do you get when you try to telnet to each of the three ports?
Check to make sure that you are forwarding the incoming port(s), all three of them to the private IP address of the Crestron Control Processor. Just opening the port isn't enough you also have to tell it where to go once it gets into the router.
All good suggestions, but I believe it has to be something that AT&T has put on their system that is blocking the connectivity. There is no reason for it to have stopped working on its own.
