NICE DCV Connection Gateway network requirements

NICE DCV Connection Gateway is usually installed on dedicated hosts, separate from NICE DCV server machines. As depicted in the high-level overview, the Connection Gateway must have network connectivity with the other components: the Clients, the NICE DCV server hosts, the Session Resolver, and the Web Resources Server.

Note

Depending on how the machines and network are configured, the network traffic that flows to and from the different components may be bound to separate network interfaces.

Please make sure your firewall rules and security groups allow the following:

  • The Connection Gateway listens for incoming connection on a TCP port specified in the configuration. This port must be reachable from the clients connecting to the gateway.

  • If QUIC support is enabled, Connection Gateway listens for incoming QUIC traffic on a UDP port specified in the configuration. This port must be reachable from the clients connecting to the gateway.

  • The Connection Gateway must be able to connect to NICE DCV server hosts on the TCP port used for DCV connections, 8443 by default.

  • If QUIC support is enabled, Connection Gateway must be able to connect to NICE DCV server hosts on the UDP port used for DCV QUIC connections, 8443 by default.

  • The Connection Gateway must be able to connect to the TCP port of the HTTPS end-point exposed by the Session Resolver.

  • If a Web Resources Server is present, Connection Gateway must be able to connect to the TCP port of the HTTPS end-point exposed by the Web Resources Server.

If you choose to have multiple NICE DCV Connection Gateway hosts to improve availability, then a network load balancer will be present between the clients and the Connection Gateway hosts. In this case the gateway must be reachable from the load balancer nodes. When using a load balancer you may also want to use a health-check connection; in this case the load balancer need to be able to reach the TCP port of the health-check service exposed by the NICE DCV Connection Gateway.

If using a Network Load Balander, refer to its documentation for more details.
