Virtual network routing gateway that supports address translation for dataplans as well as dynamic routing protocols (control plane)

A non-transitory computer-readable storage medium storing a plurality of instructions executable by one or more processors, the plurality of instructions when executed by the one or more processors cause the one or more processors to:

• couple a first gateway comprising a plurality of first ports to a first network, the first network comprising a plurality of first IP addresses in a first private address space;
• couple a second gateway comprising a plurality of second ports to a second network, the second network comprising a plurality of second IP addresses in a second private address space;
• generate a unique Network Address Translation (“NAT”) function in the first gateway for each of the plurality of ports, each of the NAT functions configured to advertise routes and translate addresses of received network packets;
• populate a unified routing table in the first gateway based on the plurality of first IP addresses in the first private address space and on translated route advertisements;
• receive an inbound network packet at one of the plurality of ports of the first gateway from the second network;
• and
• deliver the network packet according to the routing table and based on a translation of an inbound address.

A system comprising:

• a network comprising a plurality of first IP addresses in a private address space;
• and
• one or more processors configured to:
• couple a first gateway comprising a plurality of first ports to a first network, the first network comprising a plurality of first IP addresses in a first private address space;
• couple a second gateway comprising a plurality of second ports to a second network, the second network comprising a plurality of second IP addresses in a second private address space;
• generate a unique Network Address Translation (“NAT”) function in the first gateway for each of the plurality of ports, each of the NAT functions configured to advertise routes and translate addresses of received network packets;
• populate a unified routing table in the first gateway based on the plurality of first IP addresses in the first private address space and on translated route advertisements;
• receive an inbound network packet at one of the plurality of ports of the first gateway from the second network;
• and
• deliver the network packet according to the routing table and based on a translation of an inbound address.
