Can I change the MAC address of the NICs on the Coyote router?
# A: Yes. This can be useful if your ISP records the hardware signature of your computer’s NIC (to verify that you are a legitimate user of their service, and not just hacking onto their cable), and you want to insert a Coyote firewall between your computer and the ISP. Add the following command to /etc/rc.d/rc.local: ifconfig eth0 hw ether XX:XX:XX:XX:XX:XX:XX substituting the actual hexadecimal MAC address you want the Coyote box to use for the X’s.
