Port Forwarding 

To enable the modules to be accessible via the internet you will need to set port forwarding up on your LAN to WAN router. The procedure for doing this varies between make and model of router so please check the manual for your particular model. You will also need to know the WAN (wide area network) IP address for your internet connection. An internet search for “find my IP address” will usually yield several free options for this process. 

Using the configuration procedure, forward UDP port 65432 to the IP address of your KIRACCS module. To access the modules configuration screen via the internet you will also need to forward TCP port 80 to the address of the KIRACCS module. Once configured correctly, entering the IP address of your internet connection into a browser via the www should bring up the configuration screen of the KIRACCS. 

To access the configuration screen of more than one module remotely you can choose a different port, eg port 81, and then specify the port after the IP address, for example type in http://xxx.xxx.xxx.xxx:81 and then forward that port to port 80 on the chosen module.

The modules send an "acknowledge" packet back to the source when they have received and successfully processed an IR code. This is a UDP packet and on the internet UDP packets are not guaranteed to reach the destination as at busy times they can be dropped by routers in favour of a higher priority packet.

Even if an "acknowledge" packet is received it only confirms that the module has acted upon the code received it does not mean that your device has necessarily responded.

Remember that domestic broadband connections rarely provide static IP addresses so you should use a dynamic DNS service to ensure a reliable connection.
