Port Forwarding (Virtual Server) Settings - Corega COR-WLBAR-AA User Manual

4-6 Port Forwarding (Virtual Server) Settings

The Virtual Server Settings application allows up to a maximum of ten pre-defined public services and up to five user-defined services that can be accessed by external
users over the internet. Service can be applications such as a Web, Email, FTP etc. Each service is provided by a dedicated network computer (server) configured with a
fixed IP Address. Although the internal service addresses are not directly accessible to the external user, the router is capable of identifying the service requested by the
service port number. With this information the router redirects the request to the appropriate internal IP Address. To use this application, it is recommended you use a fixed
Public IP Address from your ISP. Note that the router supports only one server of any particular type.
This router also supports UPnP Forwarding. You can use either Virtual Server Settings or UPnP Forwarding by clicking the button to change setting page. Do not set the
same function server to different IP Address in different setting pages.
UPnP UPnP (Universal Plug and Play) is a standard introduced from Microsoft and UPnP Forum for interoperability. Currently, this function supported by this device
allows you to set a virtual server from a Windows OS that supports UPnP, such as Windows XP.
• UPnP Control: If enabled, the Windows XP OS will automatically communicate with the router to set up ports to allow applications such as Messenger to operate
without the user having to manually configure ports. If this section is 'grey' and cannot be accessed, then enable the UPnP option in section 4-9.
Servers The pre-determined Server type have been setup, these are: FTP, Telnet, SMTP (Email), DNS, TFTP, Finger, HTTP (Web), POP-3 (Email), NNTP (News) & SNMP. Set
up individual network computers on the LAN to act as servers and configure each with a fixed IP Address.
• Select a PC: From the drop-down menu, select the PC that will be providing the Virtual Server function.
• Enable: With a PC selected, the port forwarding will only become active if there is a tick in the enable box.
Custom Server Set up individual network computers on the LAN to act as servers and configure each with a fixed IP Address.
• Name: Give the service that you are setting up an arbitrary name.
• Protocol: You can specify the protocol type as "TCP" or "UDP" from the drop-down list. If you are not sure which one to select, choose "Both".
• Ports: Enter the desired service port numbers in the "Ports" fields.
• Select a PC: From the drop-down menu, select the PC that will be providing the Virtual Server function.
• Enable: With a PC selected, the port forwarding will only become active if there is a tick in the enable box.
