Because there are no security prevention safeguards in
place, there are also no potential link impediments either.
The use of a DMZ may therefore be desirable for
specialized applications, such as File Transfer Protocol
(FTP) or Web servers. The DMZ Hosting feature allows
one local computer to be exposed to the Internet for use
of a special-purpose service such as Internet gaming and
video conferencing.
The Motorola SBG1000 Wireless Cable Modem Gateway
serves as a DMZ to enable firewall security of protected
LAN resources. It not only offers NAT but also has
Network Address Port Translation (NAPT) to identify
source ports. For example, the firewall supports multiple
popular gaming protocols, including Quake, Unreal
Tournament, Hexen and EverQuest. The LAN administrator
can easily add support for a new gaming protocol so
online games can be established through the firewall.
The private LAN can remain secure, yet these specialized
sessions can be easily established.
The Efficiency of Shared Resources with the Security
of a Firewall
