I started my experience with ZyXEL about two years ago when I reviewed the ZyXEL Prestige 314 router. In the end, my conclusion was basically such:

“The ZyXEL Prestige 314, no doubt about it, is a great deal. A Dynamic DNS client, advanced security features, low price, DHCP features, speed, and 4 port auto-sensing built in switch make this router a very top-notch router. 

Now, the bad: for beginners setting up this router is a steep learning curve. The manual does not include clear instructions as to setting up the router and its major features. It assumes you know everything already and goes over things in major portions.”

I ran this router as my main home router for quite some time before moving on to newer technologies, and the time that I was using it I was quite satisfied with the performance.

Zyxel has offered a multitude of routers and firewalls; product lines cater both to business and home users. This particular unit, the ZyXEL ZyWALL 10 Internet Security Gateway combines many unique features which were terrific to use and configure to make my home LAN all-the-better. A short summation of this router’s features would reveal an intense content filtration system, advanced maintenance and logging, in depth help features within the router administration area, and much more. Read the material on the following pages of this review for a much more in depth review and testing of the features this router offers us.


Company supplied specifications of the ZyXEL ZyWALL 10:



VPN Connection Support


  • The ZyWALL 10 VPN support allows a business to establish a private tunnel over a public network between its headquarters and branch offices or telecommuters. The data is encrypted when traveling over the public network to ensure secure transmission between two sites. This application is a more economical replacement for leased-line service.


Real -Time Attack Alert and Log System


  • Many of today's businesses have been victimized by the costly theft of internal data. The ZyWALL 10 attack alert system warns you in real time whenever there is an attack on your network, allowing you to expeditiously repair any damage caused by the intrusion and prevent further damage to your network. A Log function will record where the attacker came from, thus tracing who is responsible for the intrusion.


Content Filtering Management


  • By using the Content Filtering feature of the ZyWALL10, schools and businesses can create and enforce Internet access polices tailored to the specific needs of the organization. The administrator selects content from a predefined list to block or monitor, such as pornography, gambling, or racial intolerance. Since content on the Internet is constantly changing, the optional Content Filtering List Subscription automatically updates the ZyWALL 10 with CyberPatrol URL Lists on a weekly basis to ensure that access restrictions to new and relocated sites are properly enforced.


Secured Default Configuration


The ZyWALL 10 has been developed to satisfy a variety of organizations by providing strong firewall capability and full VPN support. The level of security provided by the ZyWALL 10 is dependent on the specific configuration set by the administrator. By default, the ZyWALL 10 provides a secure configuration with a user-friendly interface. The interface provides both the convenience of ease of installation and quick configuration.
