UTM9 behind other Router / firewall rule

[smue2014]

I am running a UTM9S behind another router (FB7590), connected thru the WAN1.

Outbound connection is fine.

Also connecting the VOIP software from Mac to the FB.

Outgoings calls are fine.

For incoming  calls, I am wondering which inbound rule I have to establish so that they are allowed.

NAT is configured.

thx

You have a Double NAT network setup.  To know about what is Double NAT, click here.

You may want to contact the technical support for the VoIP software and ask them what TCP/UDP ports should be opened so that you can configure an inbound rule/s to allow incoming calls.  Otherwise, you may want to consider the fixes indicated in the article below:
