Corega BAR-SD Manual De Instrucciones página 18

The DMZ Host application allows unrestricted 2-way communication between a single LAN PC and other internet users or servers. This application is useful for supporting
special-purpose services such as video-conferencing and gaming, that require proprietary client software and/or 2-way user communication.
Note! That, in order to provide unrestricted access, the Firewall provided by the Corega BAR-SD Router to protect this port is disabled, thus creating a potentially
serious security risk. It is recommended that this application should be disabled when it is not in use by entering not checking the "Enable DMZ" field.
Non-standard FTP port
You have to configure this item if you want to access an FTP server whose port number is not 21. This setting will be lost after rebooting.
Packet Filters
This blocks outgoing packets. It is therefore useful for example, if you want to allow users access to Web and FTP servers, but not to newsgroups.
To block a particular IP address, enter the IP address, and the time and days that you would like the protocols to be blocked. (Note, the Simple Network Time Protocol
should be enabled for this to function).
Domain Filters
Let you prevent users under this device from accessing specific URLs.
