Port Forwarding - Conceptronic C150BRS4 Manual Del Usuario

The Conceptronic wireless router is equipped with a built-in firewall to prevent attacks from the internet
on your network. This firewall automatically blocks all incoming traffic on unused ports. When a blocked
port is needed for a service or application (for example: a FTP or Web server) you can create a Virtual
Server Rule in the configuration pages to forward the traffic.
The wireless router also supports UPnP port forwarding, allowing local UPnP applications to automatically
add port mappings to the router‟s configuration. This means that if you are using an UPnP capable
application there is no need to manually create a Virtual Server rule in the wireless router for that
application.
In the situation that UPnP is not available or a Virtual Server rule needs to be added for any other reason,
it is advised to configure the computer(s) and/or network device(s) with a fixed IP address instead of a
dynamic IP address.
Below you will find a list of some common used ports and their corresponding application:
Port Application
20 FTP data (FTP server)
21 FTP data (FTP server)
22 SSH (Secure shell)
23 Telnet
25 SMTP (Mail server – outgoing)
For more ports and their corresponding applications, see http://portforward.com/cports.htm.
Note: For detailed information about the port forwarding and DMZ options, refer to the extended user
manual (English only) on the product CD-ROM.
The wireless router can set different kind of port forwarding rules:
- Single Port Forwarding
With „Single Port Forwarding‟, you can open single ports for applications which require a single
port to operate, like a web server or FTP server.
- Port Range Forwarding
With „Port Range Forwarding‟, you can open a range of ports for applications which require
multiple ports in a row to operate, like peer-2-peer software and some games with online
multiplayer function.
To forward ports, you first need to log into the web interface of the router:

Login to the web interface as explained in chapter 5.1.

Select „Advanced‟ in the top menu bar. You will now see the advanced menu bar at the left.
