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.
