• If there is a DHCP server on your network, make sure your computer is using a
dynamic IP address. See Appendix D on page 795. Your ZyWALL is a DHCP server
by default.

IP address. See Section 3.3 on page 63.

advanced suggestions.
Advanced Suggestions
• Try to access the ZyWALL using another service, such as Telnet. If you can access the
ZyWALL, check the remote management settings, firewall rules, and SMT filters to find
out why the ZyWALL does not respond to HTTP.
• If your computer is connected to the WA N port or is connected wirelessly, use a computer
that is connected to a LAN port.
• 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.

the ZyWALL.
