It should be, ifconfig_rl0_alias0="inet 64.39.10.136 netmask 0xffffffff" ifconfig_rl0_alias1="inet 64.39.10.137 netmask 0xffffffff" ifconfig_rl0_alias2="inet 64.39.10.138 netmask 0xffffffff" ... Like so. But something is definately up since the broadcast address for these is wrong (really wrong) besides your routing problem. As to your question about lo0, if these addresses are for "interal use only," that is, the host only uses them to talk to itself (but I don't understand why someone would do that), then that _may_ work. But if the routing for these are somehow munged, the route for those may be too. -- Crist J.
