[solved] Port Forwarding / troubleshooting with netcat

[cake]

 Hello,
I am trying to figure out where the trouble is at to get port forwarding to work. I have a ISP fiber GPON modem (Chinese, remotely administered) ,that I assume is in bridge mode, I had asked the ISP to change it bridge mode, they did this from their network, the WAN interface on my OpnSense 18.1 now does the PPPoE credentials. I am confused because the public IP addressed assigned to the WAN as reported by OpnSense is not the same as my IP as reported by the websites I visit.

So my question if anybody knows, when I type from the opnsense terminal # "nc -l WAN_IP_as_reported_by_opnsense 5061" it is listening on the WAN interface and I don't need to make rules and change some obscure settings around right?

I have been using a VPS to SSH into and then use netcat from that to see if the packets arrive to my WAN Interface of OpnSense. So far no luck, I don't know where the failure is at.

Edit: The port forwarding problem is due to Carrier Grade NAT, I think opnsense was listening on the WAN at port 5061 when I asked it to from the terminal.
