    Port triggering is a specific variant of port forwarding. Unlike port forwarding, in this case the Gigaset SE551 WLAN dsl/cable forwards data from the set port block to the PC which has previously sent data to the Internet via a certain port (trigger port). This means that approval for the data transfer is not tied to one specific PC in your network, but only to the port numbers of the required Internet service.

    PCs. The private IP addresses of the servers on the local network remain protected. Internet services are addressed via defined port numbers. The Gigaset SE551 WLAN dsl/ cable needs a mapping table of the port numbers to redirect the service requests to the server that actually provides the service.

Example: the Web server has been configured to react to requests on port 8080. However, the requests from websites enter by port 80 (standard value). If you add the PC to the forwarding table and define port 80 as the public port and Port 8080 as an internal port, all requests from the Internet are diverted to the service with the port number 80 on the Web server of the PC you have defined with port 8080.
  • Page 95: Dynamic Dns

    This is handled by the dynamic DNS service (DynDNS). You can use the DynDNS service to assign your Gigaset SE551 WLAN dsl/cable an individual static domain name on the Internet even if it does not have a static IP address.
  • Page 96 When this changes, it will open a connection to DynDNS.org and update its IP address there. Please remember: You have to open an account with DynDNS.org before you can use the Gigaset SE551 WLAN dsl/cable's DynDNS function. Follow the instructions on the DynDNS.org. web- site. Then enter the user data when configuring the router.
  • Page 97: Qos (Quality Of Service)

    QoS (Quality of Service) Many communication and multimedia applications require high speed and large band- widths to transfer data between the local network and the Internet. However, for many applications there is often only one Internet connection with limited capacity available. QoS (Quality of Service) divides this capacity between the different applications and provides undelayed, continuous data transfer where data packets with higher priority are given transmission preference.

  • Page 103: Setting Wireless Security

    Setting wireless security If you are sending data over wireless channels, we recommend that you activate encryp- tion (WEP or WPA) on your wireless network components. WPA offers greater security than WEP. We therefore recommend that you choose WPA encryption if it is supported by all components in your wireless network.
  • Page 104: Wpa2-Psk And Wpa2-Psk / Wpa-Psk

    Configuring the Advanced Settings WPA2-PSK and WPA2-PSK / WPA-PSK WPA with Pre-shared key (WPA-PSK) WPA-PSK is a special WPA mode that provides encryption protection for users at home and in small companies without a company authentication server. Encryption keys are automatically generated with the Pre-shared key, and automatically changed (rekeying) and authenticated between the devices after a certain period of time Interval).
  • Page 105 WPA and WPA2 with authentication server In large networks (e.g. in companies) WPA enables the use of an additional authentica- tion service. In this case, user access is controlled by user accounts and passwords, in addition to WPA encryption. A RADIUS server acts as an authentication server. You can select the new standard WPA2 if this is supported by all components in your wireless network, or select WPA2 / WPA if you are using devices that only support WPA.
  • Page 106: Wep Encryption

    You can choose either the standard 64 bit key or the more robust 128 bit key for encryp- tion. The keys are generated in hexadecimal or in ASCII format. You must use the same keys for encryption and decryption for both the Gigaset SE551 WLAN dsl/cable and all your wireless network adapters.
