What are the options I can implement in my embedded hardware (I am programming it), so this HW will be accessible by name, using DynDNS? Several hardware devices of this type can be connected on local network. I am searching for a way, to make it easier for the customer to establish connection, from remote site (world wide). Devices have implemented web server technology, and can communicate on any port. Their main purpose is TCP to RS232 converting, done on port 4002, and optional config settings on HTTP port 80 with simple web pages. It will be perfect if no router intervention has to take place. What is the best way? Do I need to implement some protocol in the devices or ...? If I have to implement something is it ""heavy"" or just some additional port opening and responding to DynDNS server? Thanks in advance for your time :) |

Everything you need to know about the update process can be found here. That's the only bit that relates to DynDNS - updating the DynDNS hostname with the current (WAN) IP. If you don't want people to have to touch the router you'll also need to embed UPnP support to allow your device to open the relevant ports on the router. That will (obviously) only work where the router supports UPnP - if it doesn't they'll still have to manually configure the port forwarding. It's worth noting that there is no DynDNS "server" that will reach out to your device. DynDNS are only providing the DNS resolution (and update) service. |

First the hardware or a piece of hardware on the hosted network has to be able to update DYNDNS. Many routers ahve this ablity built into them from the git go. then you will have to assign a specific port for the device to be accessed on, again many of the newer routers and modems have this as part of thier set up. the method of acces then would be http://yourdomain.com:port, at that point the device would bring up a login dialog box for you user name and password. Not sure if this helps but it is a workable solution. I have a modem on one port for remote access and the router behind it on another port for remote access to the 2 devices independantly. |
