Hi,

I am trying to add hosts to rancher server. But healthcheck is stuck in a loop.

Host OS: `Container Linux by CoreOS 1632.3.0 (Ladybug)`  
Docker: `17.09.1-ce`  
Rancher Server: `latest`

My guess is the problem of UDP ports 500 and 4500. Hosts probably cannot talk to each other. But I don’t know how to fix it. It seems to me that UDP ports are already opened.

My firewall also opened these ports.

```auto

The problem is something to do with my private network setup. It worked on a new instance with no private network.
