It depends. If you have multiple addresses on the interface, use the
'alias_address' option to tell natd which to use. If the interface has
an address that changes with time (e.g. DHCP), you really should go
with the 'interface' (and 'dynamic' too). If you have one address and
it is static... it's a toss up. I think the more traditional way to go
is just specify the interface.

BTW, Mozilla is really mauling your line wrapping.
