Interesting info, I am not sure if they are the same but I was referring to the Cisco Common Packet Forwarder. Here is the discussion I had with someone struggling to get it to connect:
There’s not a lot of information online on what it actually is, just how to configure it. Although Cisco seems to suggest it allows compatibility with third-party Network Severs, so presumably it is another implementation of the UDP packet forwarder, but all I can speak to is that conversation where it was not working.
