Hello all,
First off, I'd like to thank every single person who ever contributed a line of
code or docs to FreeBSD! I've recently put togther a small machine to act as a
firewall and gateway for a home network (connected to cable modem) and the code
and docs have just been wonderful (when I don't have to ask a question, it's
straight forward <grin>)!
However, I've run into something that has bewildered me in the setup for one of
my networked machines (behind firewall).
I needed to add a default route so that all packets would be sent to the
gateway. No problem. A little looking around at /etc/defaults/rc.conf and the
man page for said file and I find:
defaultrouter
(str) If not set to NO then create a default route to this
host name or IP address (use IP address value if you also
require this router to get to a name server!)
Great! Sounds like just what I need. However, upon rebooting, things did not
work as expected. I track things down to the following code in rc.network
(my machine has been freshly CVSuped and mergemastered).
# Configure routing
if [ "x$defaultrouter" != "xNO" ] ; then
static_routes="default ${static_routes}"
route_default="default ${defaultrouter}"
fi
# Set up any static routes. This should be done before router discovery.
if [ "x${static_routes}" != "x" ]; then
for i in ${static_routes}; do
eval route_args=\$route_${i}
route add ${route_args}
done
fi
So, $defaultrouter is appended to the string "default " and set into the
route_default variable. Fine. However, route_default isn't used ANYWHERE in
this file nor seen in any other rc* files. ? Additionally, even if you don't
have a list of static routes in your /etc/rc.conf, the "if" section for the
static routes will execute (and not do very much but make "route" commands that
fail due to incorrect usage) because the static_routes variable is prepended
with "default " too ("x${static_routes}" != "x" is always true).
I think I understand what the defaultrouter variable in rc.conf was supposed to
trigger. I'm less clueful as to what static_routes is supposed to accomplish,
but my local hack to make things work the way I needed them was to make this
section of rc.network appear as follows:
if [ "x$defaultrouter" != "xNO" ] ; then
# static_routes="default ${static_routes}"
# route_default="default ${defaultrouter}"
route add default ${defaultrouter}
fi
Now upon boot, the proper "route add default" command is run with my value for
defaultrouter and the static_routes "if" statement doesn't trigger anything to
happen (which seems to be okie dokie to me).
Is defaultrouter a deprecated variable in defaults/rc.conf? It doesn't appear
to be. If not, is the above what "should be" in rc.network to accomplish this
default route? Finally, why was the static_route variable being prepended with
the word "default " too? What is the appropriate thing to do with static_routes
from rc.conf?
I have things working "ok for me" but I figured with Jordan's message yesterday
about a code slush coming at the end of this month, I'd better bring this up so
that we get it fixed.

ps: I did not send-pr this because I'm not sure what the "static_routes"
variable "should do" ....
