Hello
I've installed openvpn+Ca with webmin, on ubuntu 14.04 with 2 interfaces.
Fisrts configuration in localhost.
I've do :
edit your /etc/sysctl.conf and make sure that ip_forward is 1 (un comment it)
net.ipv4.ip_forward=1
change your vpn server routing table
sudo echo 1 > /proc/sys/net/ipv4/ip_forward
sudo iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
sudo iptables -A FORWARD -i eth0 -o tun0 -m state –state RELATED,ESTABLISHED -j ACCEPT
sudo iptables -A FORWARD -i tun0 -o eth0 -j ACCEPT
And error to start openvpn is:
