I put my class C of aliases onto lo0. I have only a single IP address on
ed0. How have you allocated your aliases and how do you send traffic to
them.
I have on www:
ifconfig ed0 203.2.135.50
ifconfig lo0 203.8.13.1 alias
...
ifconfig lo0 203.8.13.254 alias
And on the routers around the equivalent of:
route add 203.8.13.0 203.2.135.50
See if that helps.
