[Openswan Users] VPN ;- Linux as VPN client , routing problem

[John Joseph]

Hi
  I am trying to connect two linux machine , one as
VPN server and other as VPN client , I am using PSK
mode of authentication.
 I am following the links
   
http://www.jacco2.dds.nl/networking/linux-l2tp.html  
for this purpose.

Our aim is to send all packets ,other than (10.*)
through the VPN tunnel.
 

>From the Linux client after running
echo "c L2TPserver" > /var/run/l2tp-control
I am able get the VPN connection


ifconfig shows

At this stage I am able to get "route" result as
[root at localhost ~]# route

At this stage I am able to ping to my VPN server local
ip "192.168.168.167"
    

Now after modifying the route , using command

route add -net 0.0.0.0 dev ppp0

I get "route -n"
[root at localhost ~]# route -n

0      0        0 eth0


After this stage I am not able to ping or traceroute
to the VPN server or to any location
          
                    Guidance requested
               				 Thanks
