Like this in rc.conf, but with your real IP and netmask of course: ifconfig_fxp0="inet 192.168.1.2 netmask 255.255.255.0 \ media 100baseTX mediaopt full-duplex" I've seen problems with autonegotiate too. I wouldn't set up a production box without setting this manually. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-security" in the body of the message
