US Patent 11765238 Non-translated port oversubscribing for a proxy device

In some implementations, a proxy device may intercept a client session associated with a client device and a destination device. The proxy device may allocate a first port of the proxy device as a source port of a proxy session for the client session. The proxy device may determine, based on allocating the first port, whether session information associated with the proxy session would match session information associated with another proxy session. The proxy device may initiate the proxy session. A source port of the proxy session is the first port of the proxy device based on a determination that the session information associated with the proxy session would not match session information associated with another proxy session, or is a second port of the proxy device based on a determination that the session information associated with the proxy session would match session information associated with another proxy session.
