>Description:
natd must be started with either ``-n [interface name]'' or
``-a [ip address]''. Both flags are used to tell natd which
interface and IP address to use for aliasing.
Currently, rc.network is hard-coded to use ``-n
${natd_interface}''. I propose changing the behavior
such that if ${natd_interface} looks like an IP address,
use ``-a ${natd_interface}'', otherwise use ``-n
${natd_interface}''.
This will allow users who need the behavior of -a to
use our config files to start natd.
>How-To-Repeat:
Attempt to find a way to start natd with the -a flag using
our existing configuration scripts.
>Fix:
Note that this patch will only apply if the bug reported in conf/6946
has been applied first. If it has not, it is not hard to apply the
patch by hand instead.
