After running the above scripts surfing/browsing to google.com or other sites will not allow you.

You have to execute the below commands on the VPS

#ifconfig -a | grep P-t-P

inet addr:10.9.0.1 P-t-P:10.9.0.2 Mask:255.255.255.255
inet addr:127.0.0.1 P-t-P:127.0.0.1 Bcast:0.0.0.0 Mask:255.255.255.255
inet addr:8X.8X.2XX.XX P-t-P:8X.8X.2XX.XX Bcast:8X.8X.2XX.XX Mask:255.255.255.255

Note: P-t-P:10.9.0.2 - For tun0

#iptables -t nat -A POSTROUTING -s 10.9.0.0/32 -o eth0 -j MASQUERADE
#/etc/init.d/iptables save
#/etc/init.d/iptables restart

or

#iptables -A POSTROUTING --table nat -o eth0 -j MASQUERADE
#/etc/init.d/iptables save
#/etc/init.d/iptables restart

Note: Please make sure to enable the TUN / TAP / PPPD / IPTABLES on your VPS

My version of Debian seems not to include TUN / TAP driver , how could I add this module to the kernel?

You have to contact the VPS provider to enable the TUN/TAP module...
