Knowledge Base » [136377] Which IP Addresses and Ports does GP5 use?

Listed below is IP address and port information that may needed to configure firewalls, content filters, or virus scanners if you encounter problems associated with the connections between your computer and the servers.

Most installations of GP5 will not require any additional configuration beyond entering and validating the account information for a host, teacher, or student account.

However, from time to time additional steps may be required to allow GP5 to communicate to our servers in order to host sessions or participate in VoIP calls.

These situations occur if you are behind a corporate firewall or have a home firewall, content filter, or virus scanner and receive error messages such as 'Could not connect to web server' or 'Voice features disabled because UDP Traffic appears to be blocked' from GP5. GP5 will typically fail the server test (second Audio Tuning Wizard test) when communication to the servers is blocked.

Please note: GP5 can use different servers so make sure to configure the security software, firewall, content filter, etc with the correct servers for the specific version of GP5 that you are using.

We will strive to minimize changes to the addresses listed below, however, infrastructure changes may force us to change them occasionally.

For corporate locations, please contact your IT staff to make the settings.
For home users, please consult the operating manuals, online help, or software manufacturer's support center for help in configuring the firewall, content filter, or virus scanner.
