My bad. The IP can be in the same subnet as well as in a different subnet. As far as a true alias goes it is not implemented afaik. Try ifconfig in a shell and see if your aliases are listed as ips on the interface. If they where they would respond to ping and have a derived mac from the main

Brian, as a former pfsense dev (5 years) and a freebsd kernel/interface dev for 15 I do know how it works. Alias ips has worked altleast since freebsd 4. But in pfsense it was apparently added in 2.0. As I said I haven't messed with interface aliases since 2007 ish. You still did not get what I

I guess it's time for me to dig out the actual configurations to settle this. * the box with a proxy ARP VIP is running pfSense-2.0.1. (OK, it's probably due an upgrade, but when things just work they tend to be left alone :-) The WAN address is x.x.x.x/6.28, and the proxy ARP virtual IP
