System Requirements

Open

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: 

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.

In addition, TCP/UDP port 3478 should be open. This connection is bidirectional but always initiated from the corporate network/client so it is not possible for an external entity to send malicious traffic in the opposite direction.

Without port TCP/UDP 3478 open and NAT/Proxies in place, it is likely that the public-facing NAT/Proxy IP cannot be discovered and communication across the borders of the corporate network could fail.

Best Experience: 

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

Flexperto supports the integration of calendars that are hosted on Microsoft Exchange Servers (Office 365, managed or self-hosted), Outlook.com, iCloud and Google through our integration partner Cronofy.

If you use a Microsoft Exchange Server, please make sure that the following IPs have access to the Exchange Web Service interface (EWS):

• 54.93.34.174

• 3.121.21.226

• 3.122.2.191

For the best user experience we also recommend that autodiscover is turned on.

If you use Office 365, your administrator may have to whitelist the "Cronofy Connector" for your organisation. Please contact support@flexperto.com to obtain instructions on how to do this.
