Arnold J. Rimmer you have got to fix your netmask. take a look in /etc/rc.conf. try: ifconfig_ed0="inet 192.168.1.2 netmask 255.255.255.0...." "..." because i dont know if you have additional arguments or not. my 3c509 has AUI/BNC/UTP so i use ifconfig_ep0="inet 192.168.250.1 netmask 255.255.255.0 link2" jmb To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
