Configuration

The Applications & Gaming Tab > DMZ

The DMZ screen allows one local user to be exposed to the Internet for use of a special-purpose service such as Internet gaming and videoconferencing through DMZ Hosting. DMZ hosting forwards all the ports for one computer at the same time, which differs from Port Range Forwarding, which can only forward a maximum of 10 ranges of ports.

Applications & Gaming > DMZ

DMZ Hosting  This allows one local user to be exposed to the Internet for use of a special-purpose service such as Internet gaming and videoconferencing. To use this feature, select Enabled. To disable DMZ , select Disabled.

DMZ Host IP Address  To expose one computer, enter the computer’s IP address.”

Application-based QoS

Application-based QoS manages information as it is transmitted and received. Depending on the settings of the QoS screen, this feature will assign information a high or low priority for the five preset applications and three additional applications that you specify.

Enabled/Disabled  To use application-based QoS, select Enabled. Otherwise, keep the default, Disabled.

High priority/Medium priority/Low priority  For each application, select High priority (traffic on this queue shares 60% of total bandwidth), Medium priority (traffic on this queue shares 18% of total bandwidth), or Low priority (traffic on this queue shares 1% of total bandwidth).

FTP (File Transfer Protocol)  A protocol used to transfer files over a TCP/IP network (Internet, UNIX, etc.). For example, HTML pages created for a website on a local machine are typically uploaded to a web server via FTP.

HTTP (HyperText Transport Protocol)  This protocol’s main function is to establish a connection with a web server and transmit HTML pages to the client web browser.

Telnet  This terminal emulation protocol allows a user at a terminal or computer to log onto a remote device and run a program.

SMTP(SimpleMailTransferProtocol)  Ane-mailprotocol that defines the message format and the message transfer agent (MTA), which stores and forwards the mail.

POP3 (Post Office Protocol 3)  A standard mail server commonly used on the Internet. It provides a message store that holds incoming e-mail and attachments until users log on and download it.

Specific Port#  You can add three additional applications by entering their port numbers in the Specific Port# fields.

Advanced QoS

This setting allows you to specify traffic queue priority.

Fragment packet’s size of AF and BE traffic to be equal to the size of EF traffic  Select this option to fragmentize the packet sizes for AF (Assured Forwarding) and BE (Best Effort) queues so that it will increase the efficiency for transporting EF (expedited forwarding) queues. Enter a range between 68-1492 bytes.

Enable 802.1p P bits scheduling VLAN’s VID  Select this option to enable 802.1p P bits classification scheduling in the appropriate VLAN based on IEEE 802.1Q VLAN identification. Enter the VLAN VID (VLAN Identifier) number in the field.
