This section outlines how to connect your ZyWALL 100. If you want to connect a cable modem, you must
connect the coaxial cable from your cable service to the threaded coaxial cable connector on the back of the
cable modem. Connect a DSL modem to the DSL wall jack. See the Safety Warnings and Instructions
Appendix for safety instructions when making connections to the ZyWALL.
Step 1. Connecting the Console Port
Use terminal emulator software on a computer for configuring your ZyWALL via console port. Connect it to
the ZyWALL through the console port. Connect the 9-pin end of the console cable to the port labled
CONSOLE on the ZyWALL and the other end (choice of 9-pin or 25-pin, depending on your computer) to a
serial port (COM1, COM2 or other COM port) of your computer. You can use an extension RS-232 cable if
the enclosed one is too short. After the initial setup, you can modify the configuration remotely through telnet
connections.
Step 2. Connecting a Broadband Modem to the WAN Port
Step 3a. Connecting the ZyWALL to a cable modem:
Connect the port labeled WAN on the ZyWALL to the Ethernet port on the cable modem
using the Ethernet cable that came with your cable modem. The Ethernet port on a cable
modem is sometimes labeled "PC" or "Workstation".
Step 3b.
Connecting the ZyWALL to a DSL modem:
Connect the port labeled WAN on the ZyWALL to the Ethernet port on the DSL modem
using the Ethernet cable that came with your DSL modem.
Step 3c. Connecting the ZyWALL to a wireless modem:
Connect the port labeled WAN on the ZyWALL to the Ethernet port on the wireless
modem using the Ethernet cable that came with your wireless modem.
Step 3. Connecting the Dial Backup Port
The Dial Backup port is an RS-232 DB-9M connector. Connect the 9-pin female end of your modem or TA
cable to the Dial Backup port of the ZyWALL and the other end to your modem or TA.
Step 4. Connecting the DMZ Port
Connect public servers (Web, FTP, etc.) to the DMZ port to make them visible to the outside world. For a
single computer, connect the 10/100M DMZ port on the ZyWALL to the network adapter on the computer
using a crossover cable.
If you have more than one public server, then you must use an external hub. Connect the 10/100M DMZ port
on the ZyWALL to a port on the hub using a straight-through Ethernet cable.
