>Description:
It looks like the /etc/rc.d/ipfw script has a problem that used to
exist in FreeBSD 4.x a little over 10 months ago in that start-up
of natd depends on the variable ${natd_interface} being set. The
MFC by cjc on Sat. Feb 23 for /etc/rc.network fixed the problem for
/etc/rc.network for -STABLE users, but the problem still exists
for -CURRENT and 5.0-RC users today in the /etc/rc.d/ipfw script.
A proposed fix is included below as a patch.
>How-To-Repeat:
Create a custom NAT configuration, perhaps like mine, and save it
in a file (/etc/natd.conf in this example):
# CUSTOM NATD CONFIGURATION FILE - See the natd(8) man page for
# options that can be included here.
#
# Interface to do NAT on:
alias_address AA.BB.CC.DD
#
# Windows Remote Desktop stuff:
redirect_port tcp 10.0.0.1:3389 AA.BB.CC.DD:3389
#
Then configure natd in /etc/natd.conf to start like this:
# Network address translation:
natd_enable="YES"
natd_interface=""
natd_flags="-f /etc/natd.conf"
Next, reboot your system that depends on natd.
In spite of the fact that you have a valid, working natd set-up that
would work under -STABLE, natd will NOT start under -CURRENT or under
5.0-RC3. You will have to start natd by hand.
>Fix:
Apply the following patch to /etc/rc.d/ipfw:
