This indicates a problem with your routing. I am not sure of the
commands on freebsd, but on linux you would use
route -n
to show the routes. You need at least two, perhaps three routes.
One should be starting with 0.0.0.0 which is the default route. I
suspect that for some reason your ppp when it comes up again has a messed up
default route.

Similar loss of routing happened here twice since Aug 20. First time
I wasn't sure of cause and rebooted NetBSD router then the ADSL modem
after which routing was restored. Second time I found the router IP
address at the ISP had changed (I'd seen a ng posting that this could
happen and had logged the original IP) so just getting the ADSL modem
to reconnect solved it. It is still a potential problem as I haven't
worked out any method to automate reconnection in above circumstance,
although it's possible there is a setting I've missed in the modem
config. I had no reply from my ISP when I queried what had happened.

It happened again and I checked the default route per the advise that
was posted here. There wasn't one so I added it. Everything is fine
now. Seems like PPP is having trouble restablishing the default route
as the peer. I'm working on a linkup script modification that will
check to make sure that the default route is there, and if not, add it.
I'm thinking something like this would suffice for FreeBSD:

route_gateway=`route -n get default | grep gateway | awk '{print $2}'`
if [ -z `ifconfig tun1 | grep inet | awk '{print $4}'` ]
then
ifconfig_peer=`ifconfig tun0 | grep inet | awk '{print $4}'`
else
ifconfig_peer=`ifconfig tun0 | grep inet | awk '{print $4}'`
fi
if [ -n route_gateway ]
then
route add default ${ifconfig_peer}
elif [ route_gateway != ifconfig_peer ]
then
route change default ${ifconfig_peer}
fi

Note: tun0 is the DSL, tun1 is the dialup.

What do you guys think?
