Hi all,
I've read and followed those three thread's: https://forum.opnsense.org/index.php?topic=448.0 (https://forum.opnsense.org/index.php?topic=448.0) and https://forum.opnsense.org/index.php?topic=7299.msg32981#msg32981 (https://forum.opnsense.org/index.php?topic=7299.msg32981#msg32981). Especially the last one has a very specific solution but sadly that does not help with the current version of 3CX
This is what the test tells:

This is what I've setup in OPNsense (BTW: 19.1.7)

This is the Forwardings:

Doesn't make a difference if I disable or enable those rule's...
And yes as this is Multi-WAN there's a rule to tell the 3CX to only use VDSL:

The Document supplied by 3CX neither isn't very supportive, it's just telling in detail why the test is correct: https://www.3cx.com/docs/firewall-checker/ (https://www.3cx.com/docs/firewall-checker/)
So I'm kinda lost with this, and 3CX totally refuses any further support until firewall test gets "GREEN"
Reply, answer and solution to my own question:
Reread the Doc's: https://www.3cx.com/docs/pfsense-firewall/ (https://www.3cx.com/docs/pfsense-firewall/)
DON'T USE PORT LISTS IN ALIASES!!!!
