D-Link DVA-G3340S [45/78] Virtual server

Use the Virtual Server

menu to set up port

forwarding rules in the

Router. The Virtual

Server function allows

remote users to

access services on

your LAN such as

FTP for file transfers

or SMTP and POP3

for e-mail. The

DVA-G3340S will

accept remote

requests for these

services at your

Global IP Address,

using the specified

TCP or UDP protocol

and port number, and

then redirect these

requests to the server

on your

LAN with the

Private IP address

you

specify.

Virtual Server Menu and List

Remember that the specified Private IP Address must be within the useable range of

the subnet occupied by the Router.

UDP/TCP port redirection is used to direct traffic through the WAN port to the specified

servers or workstations on your private network. Port redirection can also be used to

direct potentially hazardous packets to a proxy server outside your firewall. For example,

you can configure the Router to direct HTTP packets to a designated HTTP server in

the DMZ. You can define a set of instructions for a specific incoming port or for a range

of incoming ports. Each set of instructions or rule is indexed and can be modified or

deleted later as needed.

Virtual server rules can be set up with complimentary features such as Firewall Rules,

DMZ devices and IP Filters to improve efficiency and security. Be sure to consider how

these other functions will effect the virtual server rules you have configured and

enabled.
