In addition to the "Introducing VOS Cloud CloudLinks - Prerequisites", the following sections provide the detailed protocols/ports & FQDN required for VOS Cloud connection to VOS HUB:

1. Connections to the Internet - Protocol and Ports

Protocol   Port/s    Direction    Usage                                            TCP          22       Inbound     Support, see later for whitelist                   TCP          53      Outbound     If an external DNS server is used                  TCP         443       Inbound     Support, see later for whitelist                  TCP         443      Outbound     Connect to VOS and package download               UDP          53      Outbound     If an external DNS server is used                 UDP         123      Outbound     NTP to Centos Pool, local NTP server preferred                                                                    UDP     44440-45439  Outbound     MPEG Traffic to VOS                               


The UDP connection to VOS uses packet recover techniques so the server will send back packets to the CloudLink on the same UDP "connection." The firewall must be configured to allow this traffic.

Hello Yaniv / all:  You may want to consider adding the requirement that Inbound UDP ports in the 30000-65535 range are permitted to the Cloudlink device in order to work.  Our firewall tripped us up on this requirement first time around.

If encoder and cloudlink are not in the same network (cloudlink in walled DMZ) which ports should be opened from encoder to cloudlink VM machine?
