I can connect my client to the VPN (Ubuntu 15.10) and ping other clients but still can not browse the web. I can reach a few sites (youtube.com, example.com) but most give no response including askubuntu.com

UFW is not installed and there is no nat table in iptables:

sudo iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -o eth0 -j MASQUERADE
iptables v1.4.21: can't initialize iptables table `nat': Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.

Can anyone tell me why I'm not able to reach the internet?
