I have set up a vpn server on CentOS 6
(PPTP) following this guide...
Server End
ifconfig

i have two clients successfully connected to the tunnel one is linux machine running CentOS and the other is an android device, both are assigned ips 192.168.1.201
and 192.168.1.200
respectively.
Now from my CentOS client (192.168.1.201) i cannot ping the android device (192.168.1.200), adding the route ip route add 192.168.1.0 netmask 255.255.255.255 dev ppp0
doesn't help also...
Also plz guide how can i route all my CentOS client traffic through the tunnel because when i check my public ip it shows the same ip of client's route before and after connecting to the vpn server
