Considerations for Internet Use

The Nuendo networking functions are designed mainly for use in local area networks. You could also use them directly over the internet, but this is no secure connection. For a secure communication, a VPN is highly recommended.

  • All users must use the IP addresses or domain names of the other computers in the network to establish the connection.

  • Firewalls

    Over the internet, connection and communication is established and handled via TCP/IP messages sent to the TCP ports 6991 and 6992. These ports must be open on all computers. If a firewall blocks messages to these ports and makes connection impossible, consult the documentation for your firewall.

  • Routers and Private subnets

    Only one computer in a private subnet can be connected to the internet. All computers in a NAT (Network Address Translation) subnet share the same external IP address, but the individual computers in the subnet have internal IP addresses. You must set up a port mapping from the external ports 6991 and 6992 to your internal ports 6991 and 6992, that is, the actual ports on your computer, as opposed to the ports of the subnet.

    Note

    If you want to collaborate with users whose computers reside in different subnets that use NAT, we highly recommend that you set up a VPN (Virtual Private Network). Make sure that your VPN acts as a single network and that the TCP ports 6991, 6992, and, if possible, UDP 6990 are open.
