PPP default route

[Alex Suzuki <asuzuki@bluewin.ch>]

Hi everybody,

I recently bought myself a new laptop, with a built-in ethernet
card an a lucent winmodem, which I got to work with drivers from
http://www.heby.de/ltmodem

When at home, I connect my laptop to the inhouse lan and connect
to the internet through a DSL router. Its IP address in the lan
is 192.168.1.5, the gateway is 192.168.1.1 (router).
So my standard routing table looks like this.

Destination     Gateway         Genmask         Flags Metric Ref    Use
Iface
localnet        *               255.255.255.0   U     0      0        0 eth0
default         router          0.0.0.0         UG    0      0        0 eth0

I configured my ppp connection with pppconfig, and I have defaultroute
set. However, a default route already exists (it points to the lan gateway).
When I build up a connection using pon it connects, retrieves an
IP and the nameservers, but it does NOT set a new default route,
probably because one already exists.
As soon as the connection is up, my routing table looks like this

Destination     Gateway         Genmask         Flags Metric Ref    Use
Iface
pop-ls-14-3-1.f *               255.255.255.255 UH    0      0        0 ppp0
localnet        *               255.255.255.0   U     0      0        0 eth0
default         router          0.0.0.0         UG    0      0        0 eth0

When I delete the default route before connecting using
/sbin/route del default

and then connect with the ppp service, the default route is set
to the correct (new) value.

Destination     Gateway         Genmask         Flags Metric Ref    Use
Iface
pop-ls-14-3-1.f *               255.255.255.255 UH    0      0        0 ppp0
localnet        *               255.255.255.0   U     0      0        0 eth0
default         pop-ls-14-3-1.f 0.0.0.0         UG    0      0        0 ppp0

Is there any way to automatically delete the default route when
connecting, and after disconnecting restore it?
I tried putting a script into /etc/ppp/ip-up.d and /etc/ppp/ip-down.d
but it didn't get executed. I checked the file attributes and it
was world-executable. I even put a
echo "1" >/home/user/blafile
but blafile was never created.

Can somebody help?

Thanks a lot
Alex
