Chapter 7 NAT

7.5NAT Port Forwarding Screen

Port forwarding allows users to define the local servers to which incoming services will be forwarded by creating a firewall between the internal network and the Internet. A tunnel is created so that computers on the Internet can communicate to computers on a user’s LAN through a single port. This is useful for running Web servers, game servers, FTP servers, and video conferencing and is more secure than DMZ. A common example is one computer running a Web server on port 80 and another computer running an FTP server on port 23, each with the same IP address.

ZyXEL Communications has made a significant impact in the networking industry with its innovative wireless active fiber routers, known for their robust performance and advanced features. These routers are tailored for both residential and small-to-medium business environments, providing high-speed internet access that leverages the power of fiber-optic technology.

One of the standout features of ZyXEL's wireless active fiber router is its support for ultra-fast broadband connections. By utilizing fiber optics, the router can deliver significantly higher data rates compared to traditional copper-based connections. This technology ensures that users can enjoy seamless video streaming, online gaming, and heavy downloading without interruptions.

The router boasts multiple Gigabit Ethernet ports, allowing for wired connections to devices that require a stable and high-speed internet connection.

For ease of management, ZyXEL has integrated an intuitive web interface and a mobile app that allows users to monitor and control their network settings conveniently. Users can customize their network setup, manage connected devices, and even set parental controls to ensure a safe internet environment for children.

In summary, ZyXEL Communications’ wireless active fiber router stands out with its high-speed broadband capabilities, advanced wireless technologies, robust security features, and user-friendly management interface. These characteristics make it an ideal choice for those looking to enhance their home or business networking experience, ensuring reliable and fast internet access for all connected devices.
