FreeBSD to my knowledge (and I even googled for it) doesn't support this, at least in 4.9 anyway. One thing to note when doing aliases, if all of the IP's are in the same subnet, the netmask for all aliased interfaces will be 255.255.255.255. The format for this in the rc.conf file would be: ifconfig xl0="inet 192.168.1.1 netmask 255.255.255.0" ifconfig_xl0_alias0="inet 192.168.1.2 netmask 255.255.255.255" ifconfig_xl0_alias1="inet 192.168.1.3 netmask 255.255.255.255" ... and so on. Should they be ip's from different subnets, you should use the proper netmask associated with that subnet. ifconfig xl0="inet 192.168.1.1 netmask 255.255.255.0" ifconfig_xl0_alias0="inet 192.168.2.1 netmask 255.255.255.0" ifconfig_xl0_alias1="inet 192.168.3.1 netmask 255.255.255.248" ... and so on. -- Micheal Patterson TSG Network Administration 405-917-0600 Confidentiality Notice: This e-mail message, including any attachments, is for the sole use of the intended recipient(s) and may contain confidential and privileged information.
