Detecting and correcting network interruptions using network address translation

摘要

Embodiments provide a network address translation (NAT) service for network devices. A network connection from at least one private network device to the NAT service is received and a network connection from at least one remote device to the NAT service is received. The private network device is positioned within a private network and the remote device is positioned within a public network. A network availability of the remote device is determined. If the remote device is unavailable or a network configuration setting associated with the remote device changes, the private network device is notified and a connection reset message is transmitted to the private network device.

主权项

1. A system for connecting to at least one remote device, the system comprising:
at least one virtual machine (VM) positioned within a private network; and a routing application comprising:
at least one private port, wherein the VM is communicatively coupled to the private port;at least one public port; anda network address translation (NAT) service; anda NAT database including a list of open network connections to the at least one remote device, wherein the at least one VM is associated with at least one open network connection of the list of open network connections; andwherein the NAT service instructs a processor to:
determine a network availability of a remote device communicatively coupled to the public port by monitoring a status of the public port;transmit a link interruption message to the VM upon a determination of one or more of the following: (A) a network configuration setting of the public port has changed, (B) the public port is unavailable to communicate with the remote device, and (C) a default public port associated with the remote device has changed; andtransmit a transmission control protocol (TCP) connection reset message to each VM associated with the at least one open network connection upon the determination of one or more of the following: (A) a network configuration setting of the public port has changed and (B) the public port is unavailable to communicate with the remote device.
