Abstract

The present disclosure is directed to systems and methods for dynamic firewall discovery on a service plane. The method includes the steps of identifying a source data packet for transmission from a source machine at a source site to a destination machine at a destination site, wherein the source data packet corresponds to a request for connection between the source machine and the destination machine over a WAN, inspecting the source data packet at a first firewall associated with the source site, marking the source data packet with a marker to indicate inspection by the first firewall, transmitting the marked source data packet to the destination site, determining at the destination site that the source data packet has been inspected based on the marker, and forwarding the source data packet to the destination machine at the destination site, without inspection of the source data packet by a second firewall associated with the destination site.
