IPFW2 lets you perform firewall actions on a MAC address, rather than an IP. You can configure a DHCP server to staticly allocate an IP address to that machine via something like this in {/usr/local}/etc/dhcpd.conf: host pi.codefab.com { hardware ethernet 00:00:00:00:00:00; fixed-address 66.234.138.67; } -- -Chuck
