Internet specification

In order to live webcast reliably and consistently over the internet Public-i require a dedicated wired internet connection with the minimum upload speed as follows depending on your webcasting solution. 

• HD Webcasting – 3Mbps
• SD Webcasting – 1Mbps

We also require the following ports to be open:

Outbound port access

• 54.246.86.22 - rest.public-i.tv:80,443 TCP [https]
• 176.34.99.68 - export.public-i.tv:443 TCP [https uploads]
• 176.34.99.68 - export.public-i.tv:21,20000-21000 TCP [ftps uploads]
• 54.246.86.22 - monitor.public-i.tv:2026,2027 TCP [public-i messenger]
• 54.246.86.22 - mis.public-i.tv:2024,2025 TCP [public-i mis]
• 54.247.78.247 - fms-la-01.public-i.tv:1935 TCP [video streaming]
• 81.133.180.77 - new1.public-i.info:5500-5754 TCP [VNC to office]
• 87.81.133.206 - new3.public-i.info:5500-5754 TCP [VNC to office]
• DNS TCP / UDP - to your normal DNS servers

To publish webcasts or use Just In Time (JIT) slides

• 0.0.0.0:443,80 TCP [http]

Verification Test

To test that these ports have been opened correctly, you can test from site by connecting to the wired connection and using the following command line [on Windows you might need to install it first from the Turn Windows features on or off in Add Remove Programs]:

telnet SERVER PORT

e.g. to test the video streaming port run the following command

telnet 54.247.78.247 1935

If successful you should see:    

"Trying 54.247.78.247 ...     Connected to 10.0.0.39.     Escape character is '^]' "

If the port is not open it will fail in one of two ways:

• Hang on "Trying 54.247.78.247 ..." eventually changing to "telnet: Unable to connect to remote host: Connection timed out" if packets to that address are silently dropped by the firewall [DROP]
• Return straight away with "telnet: Unable to connect to remote host: Connection refused" if packets to that address are verbosely refused by the firewall [REJECT]
