IPoE outside IP on Double NAT setup

Hi All can someone help, I have VDSL here in Australia and unifi of the ISP Modem which is a Netcomm NF20MESH .
Everything works house phone , Unifi all works well apart from one feature which is banIP added to my Home Assistant . in short it thinks all outside connections are from the ISP Modems IP not the internet IPs so it bans even my connections from outside my local network !!! .
The VDSL modem is 192.168.5.1 and the Unifi is 192.168.1.1 I believe they call this a double NAT setup…
Now I must add before I moved to this new ISP provider ( Aussie Broadband ) I was with TPG who use PPPoE and it worked like a charm when the connection was stable :blush: that’s why I moved to Aussie to try them out , but they use only IPoE …
Now I have connected NetComm & Unifi and yes you guessed were on our own they made the sale that’s all that counts for them ! .
Before I make a choice whether to get rid of Unifi or go back to another ISP who uses PPPoE I was hoping that someone from the HA community can assist … as I believe IPoE is what many ISP`s ( Internet Service Providers ) are going to eventually use IPoE … And Unifi I don’t believe will be updating anything in the near future !

I don’t mind if i have to bridge , but bridging hasn’t worked so far ! also bridging makes the home phone not available
