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

• JavaScripts (enabled by default).
• Java permissions (enabled by default).

Internet Explorer 6 screens are used here. Screens for other Internet Explorer
versions may vary.
Cannot access the
ZyWALL via the
console port.
1. Check to see if the ZyWALL is connected to your computer's console port.
2. Check to see if the communications program is configured correctly. The
communications software should be configured as follows:
•
VT100 terminal emulation.
•
9600 bps is the default speed on leaving the factory. Try other speeds in
case the speed has been changed.
•
No parity, 8 data bits, 1 stop bit, data flow set to none.
Cannot access the
web configurator.
Make sure that there is not an SMT console session running.
Use the ZyWALL’s WAN IP address when configuring from the WAN. Refer to
the instructions on checking your WAN connection.
Use the ZyWALL’s LAN IP address when configuring from the LAN. Refer to for
instructions on checking your LAN connection.
Check that you have enabled web service access. If you have configured a
secured client IP address, your computer’s IP address must match it. Refer to
the chapter on remote management for details.
Your computer’s and the ZyWALL’s IP addresses must be on the same subnet
for LAN access.
If you changed the ZyWALL’s LAN IP address, then enter the new one as the
URL.
Remove any filters in SMT menu 3.1 (LAN) or menu 11.5 (WAN) that block web
service.
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.

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

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.
