You probably could if you use assumed port 80and got your modem to send a simulated page get with the headers

VPS will do it no dramas. You'll need to write some sort of service to bind to an external IP and port. Piece of piss and heaps of code around to start from. David.

The modem requires an IP address and port number to send the messages to. I have received TCP messages before on a PC connected to the internet using TcpListener(My Static IP, port number) by opening that port number on the router but can it be done with a hosting service (pref shared hosting) instead? I imagine an IP would be necessary to attach to the hosting address but would this work given the Listener must address a port number? If not on shared hosting would a VPS do this? (Haven’t used one before.) Any pointers greatly appreciated. Regards .. Paul ..
