Port forwarding
In port forwarding, the Giga762SX WLAN dsl directs data packets from the Internet that
are addressed to a particular Port to the corresponding port of the appropriate network
component. This enables servers within the local network to offer services on the Inter-
net without them needing a Public IP address.

PPPoA is a Protocol for connecting network components in a local Ethernet network to
the Internet via an ATM network.
PPPoE
Point-to-Point Protocol over Ethernet

Private IP address
The private IP address (also known as the local IP address) is a network component's
address within the local network (LAN). The network operator can assign any address
he or she wants. Devices that act as a link from a local network, such as the Giga762SX
WLAN dsl, have a private and a Public IP address.
Protocol
A protocol describes the agreements for communicating in a network. It contains rules
for opening, administering and closing a connection, as well as in relation to data for-
mats, time frames and possibly troubleshooting. Communication between two applica-
tions requires different protocols at various levels, for example the TCP/IP protocols for
the Internet.
PVC
Permanent Virtual Circuit
A permanent virtual circuit is a logical connection in an ATM network.
QoS
Quality of Service
QoS allows network traffic to be sorted according to priorities. When this parameter is
activated, Internet telephony is given priority over other data traffic. This is a precondi-
tion for problem-free calls.
