CORRECTIVE ACTION
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.
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 close it.
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.
