Description

By default with DHCP gateways, they are not populated into the config as <gateway_item>, but can be present in a <gateway_group>. Because of this, when assigning a gateway group to an OpenVPN client that has an interface go down in the current, active tier, OpenVPN will not properly fail over. Instead, it will hang for a long time, produce errors stating that it's "unable to bind" to the interface (because it's unplugged and the gateway disappears), give an error about being unable to delete a route, and then exits on "Error 1".

If you go into each gateway item under System --> Routing, edit the gateway items without making any changes, save, and apply, the gateways will become present in the config.xml, they'll show as "Pending" in gateway statuses (rather than disappearing entirely), and OpenVPN will fail over as expected.

Either we should be adding a <gateway_item> for each gateway that is present in a <gateway_group> or we should fix OpenVPN so that it doesn't bomb out when a gateway disappears rather than transitioning to Pending.
