This is the answer to a similar question posted a few weeks ago ( and probably a few weeks before that etc..) ....................................................................

Add the following to /etc/netstart: -- # Set up any aliases to network interfaces. for device in ${interface_aliases}; do eval ifconfig_args=\$alias_${device} ifconfig ${device} ${ifconfig_args} done -- This way if you have more than one alias on an interface you just have: alias_ed1="alias x.x.x.x alias y.y.y.y alias z.z.z.z" route_alias1="x.x.x.x 127.0.0.1" route_alias2="y.y.y.y 127.0.0.1" route_alias3="z.z.z.z 127.0.0.1" static_routes="multicast alias1 alias2 alias3 loopback" All of your network config info is still in one file this way and you can easily see the aliases assigned to an interface. -- _ __ | Only my ideas here unless I say otherwise...
