Configuring the Advanced Settings
ìIn the Local IP address field, enter the IP address of the PC which provides the service.
Example: The Web server has been configured to react to requests on port 8080. However, requests from websites enter by port 80 (default setting). 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 port number 80 on the Web server of the PC you have defined with port 8080.
ìClick Add.
ìClick Delete if you wish to delete the data in the relevant line again.
ìSelect the option in the Enabled column.
ìClick OK to apply the settings.
Opening the firewall for selected PCs (Exposed Host)
You can set up a client as an exposed host in your local network. Your device will then forward all incoming data traffic from the Internet to this client. This will enable you, for example, to operate your own Web server on one of the clients in your local network and make it accessible to Internet users.
As an exposed host, your local client is directly visible on the Internet and therefore particularly exposed to risk (e.g. from hacker attacks). You should only activate this function where it is absolutely necessary (e.g. to operate a Web server) and where other functions (e.g. port forwarding) are not adequate. In this case you should take appropriate measures on the clients concerned.
Note:
Only one PC per public IP address can be set up as Exposed Host (see also the section entitled "Port Forwarding" on page 59.
ìTo set up a PC as an Exposed Host, select Exposed Host in the Address Translation (NAT) menu.
ìEnter the Local IP address of the PC that is to be enabled as Exposed Host.
ìEnter a name for the PC in the Comment field.
ìEnable the entry by selecting the option.
