Using iptables to route OpenVPN traffic
avatar

Posted on October 3, 2016 by

To have your vpn traffic be able to reach the internet you just need to add the following iptable rules:

iptables -A FORWARD -i tun0 -j ACCEPT
iptables -A FORWARD -i tun0 -o eth0 -m state –state RELATED,ESTABLISHED -j ACCEPT
iptables -A FORWARD -i eth0 -o tun0 -m state –state RELATED,ESTABLISHED -j ACCEPT
iptables -t nat -A POSTROUTING -s 192.168.0.0/24 -o eth0 -j MASQUERADE

This would take the tunnel adapter of tun0 and route the traffic through eth0 for the vpn subnet of 192.168.0.0.

Turn on IP Forwarding in Linux

Posted on August 20, 2013 by

By default for security reasons IP forwarding is turned off.  If you are setting up a router or a vpn gateway you will need to turn it back on.  You can just run the following command to turn it on.

echo 1 > /proc/sys/net/ipv4/ip_forward
