Methods, devices and systems for facilitating a connection are described. In one aspect, a method for facilitating a connection between a public internet protocol (IP) address allocated remote management server (RMS) and private IP address allocated customer-premises equipment (CPE) devices that are serviced by a home gateway device (HGD) is described. The CPE devices are located within a different type of network than the RMS. The HGD implements the method which includes: receiving, from an operation support system, a request to download a service module stored on a storage server, the request including an identifier associated with a CPE device; in response to receiving the request, downloading the service module from the storage server; initiating the downloaded service module on the HGD; and in response to initiating the service module, instructing an identified CPE device based on the identifier to establish the connection with the RMS via the HGD.
