Abstract
The disclosed computer-implemented method for preserving system contextual information in an encapsulated packet may include (1) receiving, at a computing device, a network packet from the network via a network adapter port, (2) encapsulating the received network packet with a tunnel header, where a network identifier field in the tunnel header comprises information identifying the network adapter port, (3) determine an outer Internet protocol (IP) address for the encapsulated network packet, where the destination IP address corresponds to a destination on the network, (4) addressing an outer header of the encapsulated network packet with the IP address, and (5) sending the encapsulated network packet toward the destination identified by the destination IP address. Various other methods, systems, and computer-readable media are also disclosed.
