In order to use the web configurator you need to allow:

• Web browser pop-up windows from your device.

• JavaScripts (enabled by default).

• Java permissions (enabled by default).

Note: Internet Explorer 6 screens are used here. Screens for other Internet Explorer 

versions may vary.

You may have to disable pop-up blocking to log into your device. 

Either disable pop-up blocking (enabled by default in Windows XP SP (Service Pack) 2) or 
allow pop-up blocking and create an exception for your device’s IP address.

configurator.

Make sure that there is not a telnet session running.

Use the ZyXEL Device’s WAN IP address when configuring from the WAN. Refer to 
the instructions on checking your WAN connection.

Use the ZyXEL Device’s LAN IP address when configuring from the LAN. Refer to for 
instructions on checking your LAN connection.

Your computer’s and the ZyXEL Device’s IP addresses must be on the same subnet 
for LAN access.

If you changed the ZyXEL Device’s LAN IP address, then enter the new one as the 
URL.

See the following section to check that pop-up windows, JavaScripts and Java 
permissions are allowed.

You may also need to clear your Internet browser’s cache.

In Internet Explorer, click Tools and then Internet Options to open the Internet 
Options screen. 

In the General tab, click Delete Files. In the pop-up window, select the Delete all 
offline content check box and click OK. Click OK in the Internet Options screen to

If you disconnect your computer from one device and connect it to another device that 
has the same IP address, your computer’s ARP (Address Resolution Protocol) table 
may contain an entry that maps the management IP address to the previous device’s 
MAC address). 

In Windows, use arp -d at the command prompt to delete all entries in your computer’s 
ARP table.

I cannot 
remotely 
manage the 
ZyXEL Device 
from the LAN 
or WAN.

Refer to 

 for scenarios when remote management may not be 

possible. 

Use the ZyXEL Device’s WAN IP address when configuring from the WAN. 

Use the ZyXEL Device’s LAN IP address when configuring from the LAN.
