UDP 1700 Port in the Firewall

  • What is the real requirement for UDP port 1700 in order to allow traffic from LoPy4 to TTN:

    1. Should it be open on local firewall for Outbound rules? For Inbound rules? Both? If at all?
    2. Same on the network/router filewall - is it required to be open for Outbound? Inbound? Both? If at all?
      It is for sure works when all of the above is opened...The question is if those all are really needed for connection to/from TTN to work...
