Adding interface
Colin Bester
While there are many tools out there for managing firewalls, not all small companies have the resources of larger companies. Well load out and capable GUIs can make a huge difference in assisting those that don't manage backend servers for a living. When dealing with firewalls it is even more scary.
I like what DO has done with simplify firewall management but do feel that the ability to allow/deny by interface is a crucial piece of the equation, especially with the advantages using internal private IP offers.
I'd like to suggest idea of adding ability to specify 'from interface' to cloud firewall.
