Adding a Static Route in OS X

Hello all -

Because of some weird network-in-transition issues, we need to add a
persistent static route to a couple of our iMacs that we use for
videoconferencing. With help from the man pages and some
trial-and-error, I was able to get the route added and ping from the
branch office iMac (on 192.168.x.x) to the home office computers on
(10.x.x.x) over our circuit between the offices. Unfortunately, the
route is not persistent, so on reboot it seems to disappear.

I think I need to use a switch in the route command to make the route
persistent, but I couldn't find such a switch in the man pages.
Failing that, I'd like to be able to have the system load the route
command as a Startup Item or something similar. Is there a way to do
both/either of these?

Sincerely,

Mike Simone

I think the simplest way is to add the route command to /etc/rc,
near the end, just before the "exit 0" line. Be careful editing
this file because if you screw it up, your Mac may not boot
beyond single-user mode anymore.<!-- ~MESSAGE_AFTER~ -->
