I have an Alcatel ADSL modem. I've recently configured it to use PPP, so it is always connected to my ISP provider without any need to run dialup on my pc (XP pro).
I have a static IP, and since I've re-configured my modem, the IP went to the modem, and the modem gave me an internal IP address. The problem is that I have a ftp and mail server, and no one can connect to them right now, since they get to the IP and it's the modem.
I guess this is a problem that can be fixed by configuration, but I don't know how to do that.
