Mobile wide area network IP translation configuration
View Patent ↗A method, system and non-transitory computer storage readable medium comprise operating a Wide Area Network (WAN) device according to a first Internet protocol (IP) translation mode of operation, changing an initial connectivity status between the WAN device and a WAN and transitioning from the first IP translation mode of operation to a second IP translation mode of operation that is different from the first IP translation mode of operation based on the change in the initial connectivity status.
1. A method, comprising:
operating a Wide Area Network (WAN) device according to a first Internet protocol (IP) translation mode of operation that determines how the IP address information of IP data packets are modified in transit across the WAN device;
changing an initial connectivity status between the WAN device and a WAN;
transitioning from the first IP translation mode of operation to a second IP translation mode of operation that is different from the first IP translation mode of operation based on the change in the initial connectivity status;
wherein transitioning from the first IP translation mode of operation to the second IP translation mode of operation comprises transitioning from a network access translation (NAT) mode of operation to an IP pass-through mode of operation which occurs when WAN connectivity is established.
2. The method of claim 1 , wherein the initial connectivity status is a WAN connected status.
3. The method of claim 1 , wherein the initial connectivity status is a WAN not connected status.
4. The method of claim 1 , wherein transitioning from the first IP translation mode of operation to the second IP translation mode of operation occurs when a connection to the WAN is lost and the initial connectivity status to the WAN is connected.
5. The method of claim 1 , wherein transitioning from the first IP translation mode of operation to the second IP translation mode of operation occurs when a connection to the WAN is obtained and the initial connectivity status of the WAN is not connected.
6. The method of claim 1 , further comprising transitioning from the second IP translation mode of operation back to the first IP translation mode of operation when the initial connectivity status is restored.
7. The method of claim 1 , wherein transitioning from the first IP translation mode of operation to the second IP translation mode of operation comprises transitioning from an IP pass-through mode of operation to a network access translation (NAT) mode of operation when WAN connectivity is lost.
8. A device, comprising:
a processor configured to:
operate according to a first Internet protocol (IP) translation mode of operation that determines how the IP address information of IP data packets are modified in transit across the WAN device,
change an initial connectivity status with a Wide Area Network (WAN); and
transition from the first IP translation mode of operation to a second IP translation mode of operation that is different from the first IP translation mode of operation based on the change in the initial connectivity status; and
a network interface card configured to provide WAN connectivity to at least one peripheral computer device, wherein the processor and the network interface card are communicably coupled;
wherein the transition from the first IP translation mode of operation to the second IP translation mode of operation comprises at least one of a transition from a network access translation (NAT) mode of operation to an IP pass-through mode of operation which occurs when WAN connectivity is established and a transition from an IP pass-through mode of operation to a network access translation (NAT) mode of operation when WAN connectivity is lost.
9. The device of claim 8 , wherein the initial connectivity status is a WAN connected status.
10. The device of claim 8 , wherein the initial connectivity status is a WAN not connected status.
11. The device of claim 8 , wherein the transition from the first IP translation mode of operation to the second IP translation mode of operation occurs when a connection to the WAN is lost and the initial connectivity status to the WAN is connected.
12. The device of claim 8 , wherein the transition from the first IP translation mode of operation to the second IP translation mode of operation occurs when a connection to the WAN is obtained and the initial connectivity status of the WAN is not connected.
13. The device of claim 8 , wherein the processor is further configured to transition back from the second IP translation mode of operation back to the first IP translation mode of operation when the initial connectivity status is restored.
14. A non-transitory computer readable storage medium configured to store instructions that when executed cause a processor to perform:
operating a Wide Area Network (WAN) device according
to a first Internet protocol (IP) translation mode of operation that determines how the IP address information of IP data packets are modified in transit across the WAN device;
changing an initial connectivity status between the
WAN device and a WAN; and
transitioning from the first IP translation mode of operation to a second IP translation mode of operation that is different from the first IP translation mode of operation based on the change in the initial connectivity status;
wherein transitioning from the first IP translation mode of operation to the second IP translation mode of operation comprises transitioning from a network access translation (NAT) mode of operation to an IP pass-through mode of operation which occurs when WAN connectivity is established.
