Hi,
here is what I did:
1. in the mpd.conf under l2tp_cliet section:
set iface route default
set iface up-script /usr/local/etc/mpd5/io-up
set iface down-script /usr/local/etc/mpd5/io-down
2. io-up has the following:
#!/bin/sh
/usr/bin/netstat -nr >> /tmp/io-up-netstat
LocalGW=3D`/usr/local/etc/mpd5/GW`
echo $LocalGW > /tmp/.GW
route delete $4
route add $4 $LocalGW
route delete default
route add default $4
echo $4 > /tmp/pptp_GW
cp /etc/resolv.conf /etc/rsolv.conf-1
echo nameserver `echo $6|awk '{print $2;}'` > /etc/resolv.conf
echo nameserver `echo $7|awk '{print $2;}'` >> /etc/resolv.conf
echo $0 $1 $2 $3 $4 $5 $6 $7 $8 $9 $10 >> /tmp/io-up
/usr/bin/netstat -nr >> /tmp/io-up-netstat
3. io-down has the following:
#!/bin/sh
/usr/bin/netstat -nr >> /tmp/io-down-netstat
LocalGW=3D`cat /tmp/.GW`
vpnGW=3D`cat /tmp/pptp_GW`
route delete $vpnGW
route delete default
route add default $LocalGW
cp /etc/resolv.conf-1 /etc/rsolv.conf
echo $0 $1 $2 $3 $4 $5 $6 $7 $8 $9 $10 >> /tmp/io-down
/usr/bin/netstat -nr >> /tmp/io-down-netstat
4. /usr/local/etc/mpd5/GW has the following:
#!/bin/csh -f
/usr/bin/netstat -nr | /usr/bin/grep default | /usr/bin/awk '{print $2;}'
Hope this helps.
Sami
