To change your default route without rebooting, try:
    route add default a.b.c.d

If you already have a default route, you might have to remove it first with:
    route delete default w.x.y.z

To see the routing table:
    netstat -r
or
    netstat -r -n
if your DNS doesn't work.

| Next for your route information.  You need to have a router setup.  On my

| /etc/rc.conf, where a.b.c.d is your router.  I am sure there is a way to

| that, so reboot:)
