I have a cable connection (provider is: Telenet, belgium) and I know that this provider is forcing you to use their proxy server else you haven't an internet connection. But ports 2048 + above are open to use. But I haven't a static IP address.

So: 1) can I ‘make’ a static IP address ?
2) Can my provider see that I am running a server, and has anybody did this already by this provider ?
