Can I remotely scan a customer network with Toolkit and just a CNI (C-Bus Network Interface)?
Yes, you will need to purchase and configure a CNI for the network, once you have set a static IP on the CNI you will need to setup Port Forwarding in the customers Modem/Router.
You will need to create a Port forward Rule, to allow port 10001 from External to Port 10001 Internal at the IP address of the CNI.
For help with Port Forwarding go to a service like http://www.portforward.com
Once this has been configured, you will need to configure the confection in Toolkit to use either a CNI or Wiser connection type, enter the IP address that the ISP has assigned to that customers connection (Not the internal IP of the CNI), the Port should already be set to 10001 - Do not change this.
The External IP can be either Dynamic or Static, if it's Static this will not change, but if Dynamic you will need to use a method to be able to check what the current External IP is before trying to connect.
You can use a service like http://dyn.com/dns/ sign up for an account and enter those details into the customer Modem, to check the IP you will need to go to a Command Prompt (CMD) and Ping the URL address, it will respond with the current External IP address that the ISP has assigned to the customers Internet Connection
