openvpn over pppoe

Hi there,
I have an ADSL that connects to the internet through pppoe.
Now I want to setup a VPN connection with openvpn.

The connection is made , I checked both the server/client logs of openvpn.
But I have no route through the tunnel.

In client , this is the ifconfig output :

Code:

eth0      Link encap:Ethernet  HWaddr 00:11:95:8c:07:92
          inet addr:192.168.1.9  Bcast:192.168.1.255  Mask:255.255.255.0

ppp0      Link encap:Point-to-Point Protocol
          inet addr:192.168.80.237  P-t-P:192.168.210.2  Mask:255.255.255.255

tun0      Link encap:UNSPEC  HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00
          inet addr:192.168.1.6  P-t-P:192.168.1.5  Mask:255.255.255.255

And the route output is :

Code:

Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
arsham-laptop.l *               255.255.255.255 UH    0      0        0 tun0
192.168.210.2   *               255.255.255.255 UH    0      0        0 ppp0
192.168.1.0     arsham-laptop.l 255.255.255.0   UG    0      0        0 tun0
192.168.1.0     *               255.255.255.0   U     0      0        0 eth0
link-local      *               255.255.0.0     U     1000   0        0 eth0
default         *               0.0.0.0         U     0      0        0 ppp0

How can I manage to get the tunnel work?

your local-ip address must not be the same subnet as tun0.
if your local-ip is 192.168.1.1
then assign your tun0 ip to 192.168.2.1
