Network Requirements:
Using the flexperto platform requires allowing access to its services over specific ports in order to work. A network administrator in your organization can configure these firewall settings.
Ports
Minimum Requirement:Â
The minimum requirement is that TCP ports 80/443 HTTP(S) are open. Some firewall/proxy rules only allow for SSL traffic over port 443. You will need to make sure that non-web traffic can also pass over this port and that WSS (Proxy HTTP 1.1) can be used. In addition, due to browser limitations, you should configure your proxy to not require HTTP Basic Authentication when accessing URL's and IP's listed in the whitelist further down.
...
For the best possible experience, we recommend that TCP/UDP ports 5349 is open.
Whitelisting of IP’s and URL’s
The following IP’s must be whitelisted in any case:

Calender Integration

Browser Plugins
| Info | ||
|---|---|---|
| ||
In order to interoperate with Safari Browsers (namely using the on this platform only supported h264 codec) Firefox requires a build in Plugin "openh264" to be up to date. In enterprise evironment, Firefox is typically configured to not perform automatic updates. Due to the plugin system of Firefox, this causes that openh264 files are out of date. For Safari Support find here a patch which updates the plugin files of Firefox without using Firefox Auto Update features. The archive contains a README with detailed instructions on how to apply the patch: https://flexperto.box.com/s/ctzl7whdgedi05bqzwyeyprqahape28m |
