As root, of course: $ifconfig rl0 down --- the interface is "off". $ifconfig rl0 1.2.3.4 netmask 255.255.255.0 --- the interface is back "up" at the address 1.2.3.4. You'll want to use your assigned IP and netmask (your upstream should know what this is if you don't --- but of course, it's the same as the old box, right?) Also enter it in /etc/rc.conf in this format: ifconfig_rl0="1.2.3.4 netmask 255.255.255.0" You're good as gold at the next reboot. HTH, Kevin Kinsey
