ENGLISH
The Conceptronic C300APRA2 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.
Note:
The Conceptronic C300APRA2 supports Universal Plug & Play (UPnP), which makes it possible for
UPnP compatible applications and devices such as game consoles to automatically open the ports
they need so no manual configuration is needed. However, UPnP also makes your network
environment more vulnerable for attacks. If you do not need UPnP you can disable this by
entering the web-based configuration as explained in Chapter 5.2 go to "Access Management"
"UPnP" and set "UPnP" to "Deactivated".
Below you will find a list of some common used ports and their corresponding application:

Note:
When using Virtual Server Rules, it is advised to configure the computer(s) with a fixed IP address
instead of a dynamic IP address.
