Live streaming requires ports 80, 443, 8443, 3478, 5060 and 5061 to be open at the ISP and firewall level for TCP and UDP traffic. Specifically for UDP traffic, all ports >= 1024 must be open to outbound udp traffic. A network does not need to allow all inbound traffic on all ports >= 1024 - that could potentially create a security risk. We only need to ensure the outbound udp traffic is enabled on these ports.
