It should have the same netmask of the fxp0 Nope - it is the netmask that you associate with one host... ifconfig is quite corrent in NOT rejecting it as it is right to use it = with an alias... > interface if what you mean is to have a machine with two IPs on the = same network. Nope an alias that is on the same IP segment as the main interface must = have a netmask of all ones, i.e., 255.255.255.255 or of you like that in hex 0xffffffff. Please refer to the FreeBSD /etc/defaults/rc.conf file and = see: -- #ifconfig_lo0_alias0=3D"inet 127.0.0.254 netmask 0xffffffff" # Sample = alias entry. -- Have fun...
