Advanced - Virtual Server
Use the Port Forwarding menu to create Virtual Server functions through the Router. A
Virtual Server can allow remote users to access services on your LAN such as FTP for
file transfers or SMTP and POP3 for e-mail. The DSL-504T 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. Remember that the Private IP Address must be within
the range specified for your LAN.
The Virtual Server feature employs UDP/TCP port redirection to direct traffic through
the WAN port to specified servers 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 instruction set or rule is indexed and can
be modified or deleted later as needed.
Virtual server configuration sets can be used together with complimentary features
such as Firewall Rules, DMZ devices and IP Filters to improve efficiency and security.
Consider how these other functions will effect the virtual server sets you have configured
and enabled.
To modify virtual server settings for any previously created virtual server set listed, click
on the note pad icon in the right hand column of the Virtual Servers List for the set you
want to configure. The set will appear highlighted in the list and the parameters that
have been configured appear in the settings fields above the list. Adjust the settings
as desired and click the Apply button to put them into effect.
