 This is a pretty strong indication of what you're doing wrong.  It
 looks very much like what you're trying to do is the following:
 
 	ifconfig ed0 X.Y.Z.a netmask 255.255.255.0
 	ifconfig ed0 X.Y.Z.b netmask 255.255.255.0
 
 This is not a valid combination of interface addresses.  What you must
 do is:
 
 	ifconfig ed0 X.Y.Z.a netmask 255.255.255.0
 	ifconfig ed0 X.Y.Z.b netmask 255.255.255.255
 
 and then it will work.
