Hello,
We have a network of RUT240 with OpenVPN clients configured. The server is running on a Linux machine with iptables. As we roam globally, sometimes on very expensive network, I'd like to minimize the ping traffic generated by keeping the tunnel open. I know how to configure the keepalive setting, but what else is needed in order to prevent the tunnel from being shut down when the pinging becomes less frequent?
Best Regards,
Johan
