Abstract: According to one or more embodiments of the disclosure, techniques herein provide for auto discovery of network proxies. In particular, in one embodiment, a controller in a computer network receives, from both source devices and destination devices, corresponding Transmission Control Protocol/Internet Protocol (TCP/IP) information and associated transaction identifiers (IDs) for packets sent by the source devices and for packets received at the destination devices. The controller may then correlate particular source TCP/IP information to particular destination TCP/IP information based on associated transaction IDs being the same, and can compare the correlated source TCP/IP information and destination TCP/IP information in order to determine whether a proxy device exists (e.g., and which particular type of proxy device exists) between the source device and the destination device.
