Virtual Servers Help
Virtual servers can be used for setting up public services on your LAN. A virtual server is defined as a service port, and all requests from Internet to this service port will be redirected to the computer specified by the server IP. Any PC that was used for a virtual server must have a static or reserved IP address because its IP address may change when using the DHCP function.
- Service Port - The numbers of External Service Ports. You can enter a service port or a range of service ports (the format is XXX - YYY, XXX is Start port, YYY is End port).
- Internal Port - The Internal Service Port number of the PC running the service application. You can leave it blank if the Internal Port is the same as the Service Port, or enter a specific port number when Service Port is a single one.
- IP Address - The IP address of the PC running the service application.
- Protocol - The protocol used for this application, either TCP, UDP, or All (all protocols supported by the Device).
- Status - The status of this entry, "Enabled" means the virtual server entry is enabled.
- Common Service Port - Some common services already exist in the pull-down list.
- Modify - To modify or delete an existing entry.
To setup a virtual server entry:
- Click the Add New... button.
- Select the service you want to use from the Common Service Port list. If the Common Service Port menu does not list the service that you want to use, enter the number of the service port or service port range in the Service Port box.
- Enter the IP address of the computer running the service application in the IP Address box.
- Select the protocol used for this application in the Protocol box, either TCP, UDP, or All.
- Select the Enabled option in the Status pull-down list.
- Click the Save button.
Note: It is possible that you have a computer or server that has more than one type of available service. If so select another service, and type the same IP address for that computer or server.
