diald refusing to 'reroute'

Thanks to your help my diald is up and running and it now dials out
automatically. The problem I am experiencing now is that it is refusing to
reroute the default connection to ppp0. The sl0 connection is being handed
over to ppp0, but it is just not being set as the deafult gateway. In my
network setup I have no default gateway set. In my /etc/ppp/options file I
have no configurations added and left that all up to diald.conf, just like
the man page tells you. In the syslog file I am receiving this " unknown
option 'reroute' ". Here is my diald.conf file:

#diald.conf file for diald

#fifo /etc/diald/diald.ctl

debug 31

accounting-log /var/diald/log

mode ppp

device /dev/ttyS0

speed 38400

strict-forwarding

redial-timeout 10

pppd-options user "username"

include /usr/lib/diald/standard.filter

I have tried adding "/sbin/route add -net 0.0.0.0. dev $1" to the beginning
of the ip-up script. This works, but as soon as the link is dropped diald
doesn't pass back the default connection to sl0. Any ideas will be welcome.



Thanks
