Google Hangouts Firewall Ports

Our firewall was configured as per Google’s documentation to allow the Google Hangouts nee Talk client and the Android Google Hangouts app to connect. but to no avail.
With a little bit of troubleshooting I found that an additional port needed to be opened too. So here’s the firewall ports you need to open for Google Talk:

• 80 TCP

• 443 TCP

• 19302 – 19309 TCP and UDP

• Additional Ports for various clients

  Ports

  5222, 5223, 5224

  5228 and 5229
