FYI the correct FreeBSD rc.conf setting would be: (assuming your interface is em0) ifconfig_em0="inet 209.160.65.133 netmask 0xfffff800" ifconfig_em0_alias0="inet 209.160.68.112 netmask 0xffffffff" And to fix by hand: (assuming your interface is em0) # ifconfig em0 inet 209.160.68.112 netmask 0xffffffff Wietse
