My OpenVPN instances are unreachable after installing an agent

When your OpenVPN instances are unreachable after installing an agent, it could be because the Deep Security Agent has disabled iptables. To avoid firewall conflicts, the Deep Security Agent disables iptables by default.

OpenVPN relies on iptables to function properly. To prevent the Deep Security Agent from disabling iptables, see How to use Deep Security agents with iptables.
