• If you've forgotten the ZyWALL's IP address, you can use the commands
through the console port to check it. Connect your computer to the CONSOLE
port using a console cable. Your computer should have a terminal emulation
communications program (such as HyperTerminal) set to VT100 terminal
emulation, no parity, 8 data bits, 1 stop bit, no flow control and 115200 bps port
speed.
I cannot access the Internet.
• Check the ZyWALL's connection to the Ethernet jack with Internet access. Make
sure the Internet gateway device (such as a DSL modem) is working properly.

wizard again and make sure that you enter the correct settings. Use the same
case as provided by your ISP.
