In October i posted a blog about setting up your OpenVPN server in 2 minutes.
This blog is a addon to your existing configuration to route all traffic over the VPN.
Change server configuration
go to the config file (/etc/openvpn/server.conf) and add the following lines:
push "redirect-gateway def1" push "dhcp-option DNS " push "dhcp-option DNS 184.108.40.206"
Restart your OpenVPN daemon
sudo /etc/init.d/openvpn restart
Change client configuration
Change your client config, and add the following line
Change IP Tables
Last thing to do is change your iptables to NAT traffic to the internet. (make sure you have the right to do this or run this as root)
iptables -I FORWARD -i tun0 -o wlan0 \ -s 10.8.0.0/24 -m conntrack --ctstate NEW -j ACCEPT iptables -I FORWARD -m conntrack --ctstate RELATED,ESTABLISHED \ -j ACCEPT iptables -t nat -I POSTROUTING -o wlan0 \ -s 10.8.0.0/24 -j MASQUERADE
Caption: * tun0: your virtual VPN network interface * eth0: your normal network interface (to make sure you will use the right interface, check with “ifconfig”) * 10.8.0.0: your VPN network IP range
