what is an open port with a commplex-link?

I'm trying to discover what service is trying to connect to an open port. One day it was called service "freedom". Scanning for open ports, this port was first to appear with the description commplex-link. The another service described with more information by Norton security pointed to an app associated with my modem trying to link to this port, the Netgear Genie App. I am blocking all connections in firewall settings. Also Netgear Genie App is notifying me that it is trying to make changes. I don't get enough info from the app to allow what it is trying to do. The Netgear product is a modem with router, in which the router is disabled so the modem can be used as a bridge to my Airport TC.
