Abstract
In one embodiment, a method includes receiving on a private network at a Network Address Translation (NAT) gateway, a Generic Routing Encapsulation (GRE) packet comprising a client address and a GRE node private Internet Protocol (IP) address, mapping the client address to the GRE node private IP address at the NAT gateway, storing the mapping at the NAT gateway, replacing the GRE node private IP address in the GRE packet with a public IP address of the NAT gateway, and transmitting the GRE packet from the NAT gateway on a public network. Wherein the mapping is used in forwarding packets received on the public network at the NAT gateway to a client on the private network. An apparatus and logic are also disclosed herein.
