Hello.

Is it possible to add more than one interace to flannel to choose from for custom cluster created in Rancher?  
According to flannel documentation, it is possible:  
–iface="": interface to use (IP or name) for inter-host communication. Defaults to the interface for the default route on the machine. **This can be specified multiple times to check each option in order**. Returns the first match found.

How should I edit network part in cluster yaml? Could it be like this?  
`flannel_iface: eth1,enls8`

Or can I change those settings only for specific node?

Thanks. Best regards, Michal
