With SIP-Spoofing (Static IP Spoofing) it is possible to make a pc directly reachable from the internet, while the modem itself controls the connection. Some routing tricks provide that the public IP-address becomes attached to the ethernetcard from the pc which is connected to the modem. With SIP-Spoofing you don't need mpd or pptpclient anymore.

Today I've configured my ADSL modem and FreeBSD to get SIP-Spoofing to work and with great success! Below are links to pages I used, all pages are in Dutch and are about the Alcatel SpeedTouch Pro ADSL modem in combination with mxstream, a Dutch ADSL subscription from KPN Telecom.
