Appendix C: Finding the MAC Address and IP Address for 

Your Ethernet Adapter

This section describes how to find the MAC address for your computer’s Ethernet adapter so you can use the MAC 
filtering feature of the Gateway. You can also find the IP address of your computer’s Ethernet adapter. This IP 
address is used for the Gateway’s filtering, forwarding, and/or DMZ features. Follow the steps in this appendix to 
find the adapter’s MAC or IP address in Windows 98, Me, 2000, or XP.

1. Click Start and Run. In the Open field, enter winipcfg. Then press the Enter key or the OK button. 

2. When the IP Configuration screen appears, select the Ethernet adapter you have connected to the Gateway 

via a CAT 5 Ethernet network cable. See Figure D-1.

3. Write down the Adapter Address as shown on your computer screen (see Figure D-2). This is the MAC address 

for your Ethernet adapter and is shown in hexadecimal as a series of numbers and letters.

The MAC address/Adapter Address is what you will use for MAC filtering. The example in Figure D-2 shows 
the Ethernet adapters’s MAC address as 00-00-00-00-00-00. Your computer will show something different.

The example in Figure D-2 shows the Ethernet adapter’s IP address as 192.168.1.100. Your computer may 
show something different.

Note: The MAC address is also called the Adapter Address.
