Setting up forwarding on client for OpenVPN for client to reach each other on CentOS 6.xx

openvpn-forwarding.sh

service openvpn start

# Now we need to enable IP forwarding. So open the file /etc/sysctl.conf and set ‘net.ipv4.ip_forward’ to 1.
net.ipv4.ip_forward = 1

# To make the changes to sysctl.conf take effect, use the following command.
sysctl -p

# Route Iptables:
# The rule below will work fine on xen and KVM based VPS’s but for OpenVZ use the OpenVZ iptable rule instead:
# iptables -t nat -A POSTROUTING -s youropenvpnendpointaddress/yournetmask -o eth0 -j MASQUERADE
