The netmask for the alias is certainly wrong!!! The 255.255.255.255 netmask is only used for successive aliases counting from the second - that is if it is the first one in a given subnet, it will have the "real" netmask - that is whatever is set as netmask on the router interface 1.2.3.36. It should work then.
