Accessing Netlinx Master Across WAN

TurnipTruck

Greetings,

I am setting up a system that I would like to be able to upload code to across the Internet. Never having set a system up like this before, could someone please give me a quick rundown on how the Master needs to be set up at the remote site, and how to access it from the office, avoiding and potential issues. Thank you.

First thing, were is the box going? Office or home? You need to know if you have to talk to any of the network administrators before you shove a box on their line.

It's going on a LAN which I administer. I have access to change port forwarding, etc. I guess I was a bit vague in my original question. What incoming ports need to be forwarded to the Netlinx master in order to use G3 web control and to be able to upload code and TP user interface files to the system? And any other hints or tricks from those more experienced than myself.

The Master is already on the LAN with an assigned IP address and working normally.

Thanks!!!

port 1319 needs to be open for starts. Have you saved the G3 panel as a HTML yet? Can you telnet to the master already and see what's up? Have you defined your webpage in your program?

TurnipTruck

Yes, the G3 panel design is loaded, accessible and working fine over the LAN.

NetLinx Studio and TPDesign4 use port 1319.
The web interface through which G4 control is established uses port 80, and the web control itself uses port 5900. It may also need port 5800; I've had mixed results. Keep in mind the VNC protocol used by G4 Web Control connects to the panel, the web interface is just a gateway. I generally forward 5900 to the panel itself and use Real VNC rather than the browser applet.
The master also has an FTP and Telnet server on the standard ports; the Telnet can be re-mapped in the NetLinx to whatever you want. I haven't seen too many cases where I cared about the FTP.

Thanks you for your reply. I am trying to serve up a G3 panel over the WAN using the built in G3 web control in an NI-2000. I have so far been unsuccessful over WAN with port 1319 routed to the master. It works fine on the LAN.

Are you running any firewalls on your side ? Late last friday night I logged onto my office computer and did 7 complete FTP's to different rooms from my bedroom(bored-wife was working and kids were asleep.) with no problems. You mention that it works on the LAN but not the WAN. Either there is a blocked port or it is not being address properly between the two. Does any connection work over the WAN?

TurnipTruck

I have port 1319 mapped to the IP of my Netlinx Master. Yes, many things work from WAN connections to my LAN. Is there anything more to do to access the system besides typing "http://<IP ADDESS>:1319 into the browser? When doing this from the outside, browsers return page cannot be displayed errors.

Thomas Hayes

When I type my particular IP address I get the following.
1- Security log in page is displayed.
2- A page that has the AMX logo in the top left corner with the following tabs: web control, security, system, show devices, network.
3- I just click on whats listed under the "web control" and wam bam I'm looking at it.

Is your system showing anything like this?

You won't be able to browse to port 1319... you'll need to forward port 80 and 10500 to the IP of your Netlinx Master in order to do G3 Web Control externally.

With port 1319 forwarded, are you able to establish a connection with the master through Studio?

ICSP is using TCP and UDP.
On my experience, some routers must be set for TCP and UDP in two steps.

To get G3 Web control opened through the router/firewall you need to forward ports 80 for a http connection, 443 if you are using https (Master Builds greater than 117), and port 10500. Port 10500 is the communication channel between the G3 Web Control device Applet running in the browser and the Master.

Port 1319 is the registered ICSP port and is used for communication between the NetLinx master, NetLinx IP devices, and NetLinx software applications (i.e. NetLinx Studio, TPD4, etc.) You cannot do [url]http://[/url]<ip here>:1319 as 1319 is not an http port.

Telnet is port 23 and only needs to be forwarded if you are going to use telnet. FTP uses ports 20 and 21 and again, only needs to be forwarded if you use FTP.

To summarize, a minimal port forward list to allow Porgram updates, firmware updates, and G3 Web Control port is:

80, 1319, 10500

optionally you can add telnet (23) https (443) and FTP (20,21)
