Browse Source 
* Digital Ocean firewalls don't yet support the required
IP tunneling protocol so Calico cannot be used without
disabling firewalls right now.

!!! warning
Do not choose a `controller_type` smaller than `2gb`. The `1gb` droplet is not sufficient for running a controller and bootstrapping will fail.
!!! bug
Digital Ocean firewalls do not yet support the IP tunneling (IP in IP) protocol used by Calico. You can try using "calico" for `networking`, but it will only work if the cloud firewall is removed (unsafe).
