I have an interface configured with a primary address and 2 aliases like so: inet 173.xxx.xxx.254 255.255.255.224 NONE inet alias 173.xxx.xxx.251 255.255.255.255 inet alias 173.xxx.xxx.252 255.255.255.255 If I visit http://www.whatismyip.com I am expecting to constently see it report the first (173.xxx.xxx.254) address, but instead it reports any of the three addresses. How can I guarantee that all traffic from this machine is seen as coming from the main IP address?
