Methods for establishing a stateless extranet in a secure communication network include transmitting a consumer NHOP to a provider CPE from a consumer CPE in a control plane. The consumer NHOP is associated with at least one attribute of an NHOP, including an encryption key available with the consumer CPE, to establish a secure communication tunnel in a data plane. The consumer CPE receives a service definition over the control plane associated with a service available with the provider CPE. A service anchor point is created based on an identifier of the service definition. A network address translation (NAT) IP request is transmitted to the provider CPE. The consumer CPE receives a NAT IP from the provider CPE in response to the NAT IP request. The NAT IP is associated with the service anchor point of the consumer CPE. A stateless service is thereby instantiated on the consumer CPE.
