How to restart natd remotely

Be careful, when you want to make changes to natd.conf, and then restart from a remote console. If you just kill -9 natd, then you will get locked out immediately, without chance to start it again. Needless to say, this would lead to jumping in a car and rushing down to the office.

So, first, let's have a backup plan.

ipfw add 10 allow all from [myIpAddress] to me

Second, run

kill -9 [natd_pid] && /sbin/natd -f /etc/natd.conf -a [natd_external_address]

Of course, your natd flags may vary.
