Sorry, should have elaborated. This would be done by using the
-alias_address option in natd, rather than the -interface option. man
natd for more info.
KeS
-alias_address | -a address
Use address as the aliasing address. Either this or
the
-interface option must be used (but not both), if the
-proxy_only option is not specified. The specified
address
is usually the address assigned to the ``public''
network
interface.
All data passing out will be rewritten with a source
address
equal to address. All data coming in will be checked
to see
if it matches any already-aliased outgoing connection.
If it
does, the packet is altered accordingly. If not, all
-redirect_port, -redirect_proto and -redirect_address
assign-
ments are checked and actioned. If no other action
can be
made and if -deny_incoming is not specified, the
packet is
delivered to the local machine using the rules
specified in
-target_address option below.
