Port Forwarding

In port forwarding the Gigaset SE551 WLAN dsl/cable 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 area network to offer services on the Internet 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.

PPPoEPoint-to-Point Protocol over Ethernet

PPPoE is a Protocol for connecting network components in a local Ethernet network to the Internet via a modem.

Private IP address

The private IP address (also known as the local IP address) is a network component's address within the local area 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 Gigaset SE551 WLAN dsl/cable, have a private and a Public IP address.

Protocol

A protocol describes the agreements for communicating on a network. It contains rules for opening, administering and closing a connection, as well as about data formats, time frames and handling possible errors. Communications between two applications require different protocols at various levels, e.g. the TCP/IP protocols for the Internet.

Public IP address

The public IP address (also known as the global IP address) is a network component's address on the Internet. It is assigned by the Internet Provider. Devices that create a link from a LAN to the Internet, such as the Gigaset SE551 WLAN dsl/cable, have a public and

aPrivate IP address.Radio networkSee WLANRekey Interval

The rekey interval is the period after which new keys are automatically generated for data encryption with WPA-PSK.

Remote Management

Remote Management refers to the ability to manage a network from a network component that is actually outside the local area network (LAN).
