Chapter 1 Getting To Know Your ZyXEL Device

The ZyXEL Device is ideal for high-speed Internet browsing and making LAN-to-LAN 
connections to remote networks. The ZyXEL Device is compatible with the ADSL/ADSL2/
ADSL2+ standards. Maximum data rates attainable for each standard are shown in the next 
table.

Note: If your ZyXEL Device does not support Annex M, the maximum ADSL2/2+ 

upstream data rate is 1.2 Mbps. ZyXEL Devices which work over ISDN do not 
support Annex M. 

The standard your ISP supports determines the maximum upstream and 

downstream speeds attainable. Actual speeds attained also depend on the 
distance from your ISP, line quality, etc.

Once you connect and turn on the ZyXEL Device, it automatically detects the Internet 
connection settings (such as the VCI/VPI numbers and the encapsulation method) from the 
ISP and makes the necessary configuration changes. In cases where additional account 
information (such as an Internet account user name and password) is required or the ZyXEL 
Device cannot connect to the ISP, you will be redirected to web screen(s) for information input 
or troubleshooting.

The Any IP feature allows a computer to access the Internet and the ZyXEL Device without 
changing the network settings (such as IP address and subnet mask) of the computer, when the 
IP addresses of the computer and the ZyXEL Device are not in the same subnet.

The ZyXEL Device is a stateful inspection firewall with DoS (Denial of Service) protection. 
By default, when the firewall is activated, all incoming traffic from the WAN to the LAN is 
blocked unless it is initiated from the LAN. The ZyXEL Device firewall supports TCP/UDP 
inspection, DoS detection and prevention, real time alerts, reports and logs.
