Steve Having just implemented IP aliasing on a NIC in our FreeBSD 4.5 server and goten it to work, my first thought is that the netmask for the alias should be 255.255.255.255 if, as in this case, both IPs should sit on the same subnet. Don't ask me why, but it does work. I believe I read it in the handbook or the man pages somewhere. Good luck.
