Re: openvpn clients have no internet connection

... my firewall script. Probably not a good idea. If you are using the iptables service, all rules should be in /etc/sysconfig/iptables.

Re: openvpn clients have no internet connection

Of course you have to replace br0 with whatever is the inernet-facing adapter in your setup. The point is that you need to forward traffic in both directions: from tunnel to internet and vice versa. These are the changes I made to my firewall script. Unfortunately it did not yield desired results. ...

Recovering system...
