Perhaps your modem doesn't use UPnP technology. That means you should manually forward a port (open a port.) I had to do the same thing when I went up from dial up last year.

These steps are very important to follow in order & do carefully:

1. Set up a Static IP address. http://www.portforward.com/motorola/sbg900-dhcp.htm (& use the link at bottom of that page also)

2. Forward a Port using Port 6346 See http://www.portforward.com/motorola/...forwarding.htm

3. Manual port forward instructions & sample image & 2 posts after that.

Good luck! (By the way if you were using net games or video conferencing you'd need to do the same thing but open many more ports.)
