Bridge Mode (For a Single PC) (RFC 1483 Bridged Mode)
If the ISP limits some specific computers to access Internet, that means
only the traffic to/from these computers will be forwarded and the other
will be filtered. In this case, bridge modem is used to connect to the ISP.
The ISP will generally give one Internet account and limit only one
computer to access the Internet. Check with your ISP to determine if this
mode is used for your DSL connection. To configure this page correctly,
you should also obtain the information on this page from your ISP.

CBR (constant bit rate): the CBR service class is intended for
real-time applications, for example, those requiring tightly
constrained delay and delay variation, such as voice and video
applications. The consistent availability of a fixed quantity of
bandwidth is considered appropriate for CBR service.
■
UBR (unspecified bit rate): the UBR service class is intended for
delay-tolerant or non-real-time applications, for example, those
which do not require tightly constrained delay and delay variation,
