Advanced > Virtual Server

Using the Configuration Menu

The DI-824VUP+ can be configured as a virtual server so that remote users accessing

Web or FTP services via the public IP address can be automatically redirected to local

servers in the LAN (Local Area Network).

The DI-824VUP+ firewall feature filters out unrecognized packets to protect your LAN

network so all computers networked with the DI-824VUP+ are invisible to the outside

world. If you wish, you can make some of the LAN computers accessible from the

Internet by enabling

Virtual Server.

Depending on the requested service, the DI-824VUP+

redirects the external service request to the appropriate server within the LAN network.

the virtual service.

Private IP

applications work with the DI-824VUP+. If you need to run applications that require multiple

connections, specify the port normally associated with an application in the

Trigger

field, then enter the public ports associated with the trigger port into the

Incoming Ports

field.

At the bottom of the screen, there are already defined special applications. To use them,

select one from the drop down list and select an ID number you want to use. Then click

the “Copy to” button and the router will fill in the appropriate information to the list. You

make an application work, try using DMZ host instead.

Note!

Only one PC can use each Special Application tunnel.

This is the port used to trigger the application. It can be

either a single port or a range of ports.

Public Ports

This is the port number on the WAN side that will be used to

access the application. You may define a single port or a range
