High Speed Internet Access
The ZyXEL Device is an ADSL router compatible with the ADSL/ADSL2/ADSL2+ standards. Maximum data rates attainable for each standard are shown in the next table.
Table 1 ADSL Standards
DATA RATE | UPSTREAM | DOWNSTREAM |
STANDARD | ||
|
|
|
ADSL | 832 kbps | 8Mbps |
|
|
|
ADSL2 | 3.5Mbps | 12Mbps |
|
|
|
ADSL2+ | 3.5Mbps | 24Mbps |
|
|
|
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.
Zero Configuration Internet Access
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.
Any IP
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.
Firewall
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.
Content Filtering
Content filtering allows you to block access to forbidden Internet web sites, schedule when the ZyXEL Device should perform the filtering and give trusted LAN IP addresses unfiltered Internet access.
