Boundary interfaces for communications networks are disclosed. An example method includes configuring, with a processor, a first policy for a first network interface of a computing device in response to an input from a first network administrator of a first network; configuring, with the processor, a second policy for a second network interface of the computing device in response to an input from a second network administrator of a second network, the second network administrator being different than the first network administrator; displaying the second policy to the first network administrator; and displaying the first policy to the second network administrator.
