The desired functionality of the STWireless ADSL router in this
model, is maximum transparency. Packets arriving on inbound
ports must be forwarded transparently to outbound ports. All
intelligent decisions will be made in either the single PC, or the
home gateway.
In fact, this functionality has been offered by voiceband modems
for a long time, but then with an important speed limit.
The IEEE 802.1D transparent databridge, the PPPoAĆtoĆPPTP relay
and the PPPĆtoĆDHCP Proxy - all bound to the Ethernet port and
the ATM switching capabilities of the ATMF25.6 port -, adhere
best to this model.
