Abstract: A node is configured to receive, from a second node, a request to establish a session; perform, in response to the request, a network address translation (NAT) operation to establish the session, the NAT operation causing a first port block to be allocated to the session, the first port block including a first set of ports via which traffic, associated with the session, is transported; determine that the set of ports are no longer available for the session; determine whether a quantity of times that the first port block has been allocated to the session is greater than a threshold; and retain the first port block, for the session, when the quantity of times that the first port block has been allocated to the session is not greater than the threshold.

Abstract: A network device may receive a request from a local device to establish a connection with a another device. The request may include an internal network identifier of the local device. The network device may evaluate a plurality of external network identifiers, associated with the network device based on selected criteria. The network device may also, or alternatively, evaluate the external network identifiers by identifying an external network identifier that is already mapped to, or paired with, the internal network identifier. The network device may select an external network identifier, of the plurality of external network identifiers, based on the evaluation and establish the connection requested by the local device using the internal network identifier and the external network identifier.
