Conguring Your 
Macintosh Computer
You may nd that the instructions here do not exactly match your 
screen. This is because these steps and screenshots were created 
using Mac OS 8.5. Mac OS 7.x and above are all very similar, but may 
not be identical to Mac OS 8.5.
Step 1. Congure TCP/IP Settings
After you have completed the hardware setup, you need to congure 
your computer to connect to your Barricade. You need to determine 
how your ISP issues your IP address. Many ISPs issue these 
numbers automatically using a networking technology known as 
Dynamic Host Control Protocol, or DHCP. Other ISPs will specify your 
IP address and associated numbers, which you
must enter manually. This is also known as a static IP address. How 
your ISP assigns your IP address determines how you will congure 
your computer.
1. Pull down the Apple Menu. Click 
“Control Panels” and select TCP/IP.
2. In the TCP/IP dialog box, make 
sure that “Ethernet” is selected in 
the “Connect Via:” eld. If “Using 
DHCP Server” is already selected 
in the “Congure” eld, your computer 
is already congured for DHCP. 
Close the TCP/IP dialog box, and 
skip to Step 2 “Disable HTTP Proxy.”
3. All the information that you need 
to record is on the “TCP/IP” dialog 
box. Use the space below to record 
the information.
