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.
