Port triggering is a special variant of port forwarding. Unlike port forwarding, the Gigaset SX761 dsl forwards the data from the 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 the network, rather to the port numbers of the required Internet service.
Page 51
IP addresses of PCs in the local network are converted to the router's public IP address when accessing the Internet. You can use the NAT settings to configure the Gigaset SX761 dsl to carry out the follow- ing tasks:...
Configuring Advanced Settings Port Triggering If you configure port triggering for a certain application, you must identify a trigger port and the protocol (TCP or UDP) this port uses. You can then assign the public ports that must be opened for the application and this trigger port. You can select known Internet services for this purpose or assign ports or blocks of ports manually.
Apply the settings by clicking OK. Port Forwarding If you configure Port Forwarding, the Gigaset SX761 dsl outwardly assumes the role of the server. It receives requests from remote users under its public IP address and auto- matically redirects them to local PCs. The private IP addresses of the servers on the local network remain protected.
Configuring Advanced Settings You can use – a single port number, – several port numbers separated by commas, – port blocks consisting of two port numbers separated by a dash, or – any combination of these (for example 80,90-140,180). ì In the Local port field, enter the internal port number to which service requests are to be forwarded.
This task is performed by the dynamic DNS service (DynDNS). You can use the DynDNS service to assign the Gigaset SX761 dsl an individual fixed domain name on the Internet even if it does not have a static IP address.
Page 56
Configuring Advanced Settings One possible service is DynDNS.org (http://www.DynDNS.org). If you have activated the device's DynDNS function, it will monitor its public IP address. When this changes, the device will open a connection to DynDNS.org and update its IP address there. Note: You must have an account with the service you have chosen (e.g.
Configuring Advanced Settings Routing Your Internet service provider can permit you to set up a number of connection services. The entire data traffic between your local network and the Internet uses the first con- nection service (route) by default. After setting up various connection services (page 39), you can change this default route and set up additional routes by assigning data traffic to other connection services.
