Abstract
A method for forwarding a connection at an interconnecting device is described. The method includes receiving from an originating device an incoming connection at an incoming port, determining by at least one hardware processor whether port translation is implemented for the incoming port, in case port translation is implemented for the incoming port, returning to the originating device by the at least one hardware processor a challenge intended to distinguish humans from computers, verifying by the at least one hardware processor that a response received in response to the challenge is a correct response to the challenge, and, in case the response is a correct response to the challenge, forwarding, by the at least one hardware processor, the connection to a translated port corresponding to the incoming port according to the port translation.
