Exemplary methods, computer-readable media, and systems for maintaining an inbound network path to a host in a sleep or a hibernation mode behind a plurality of network address translators (NAT) or firewalls. A network interface card (NIC) of a host is configured to periodically send or receive keep-alive packets. These packets enable network mappings that would ordinarily expire while a host is in a sleep or a hibernation mode. Power is maintained on the NIC while the host is in such mode, and the NIC responds as programmed including waking a host upon a certain event, such as receiving a data packet matching a preconfigured signature. During such time, the host may be in a wake on LAN mode.
