Hi, You need to either set the netmask of the alias address to 255.255.255.255, or add a manual route statement:
route add <alias_address> 127.1 That will do it. Then you will be able to get to the alias address from the aliased machine. On a side note: 1. Does anyone know how to get this same thing to work with natd?? i.e. is there a way for the natd box to see ports that it is redirecting as they would be seen from the outside world?? I am pretty sure that the Cisco PIX firewalls will do this, but I was wondering if it was possible with FreeBSD.
