D-Link DIR-635 User Manual

Section 3 - Configuration

The DIR-635 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 DIR-635 firewall feature filters out unrecognized packets to protect your LAN network so all computers networked

with the DIR-635 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 DIR-635 redirects the external

service request to the appropriate server within the LAN network.

The DIR-635 is also capable of port-redirection meaning incoming traffic to a particular port may be redirected to a

different port on the server computer.

Each virtual service that is created will be listed at the bottom of the screen in the Virtual Servers List. There are

pre-defined virtual services already in the table. You may use them by enabling them and assigning the server IP to

use that particular virtual service.

Application Rules

Some applications require multiple connections, such as Internet gaming, video conferencing, Internet telephony and

others. These applications have difficulties working through NAT (Network Address Translation). Special Applications

makes some of these applications work with the DIR-635. If you need to run applications that require multiple connections,

specify the port normally associated with an application in the “Trigger Port” field, select the protocol type as TCP or

UDP, then enter the firewall (public) ports associated with the trigger port to open them for inbound traffic.

The DIR-635 provides some predefined applications in the table on the bottom of the web page. Select the application

you want to use and enable it.
