Hey Guys,
A bit of a newbie here but I recently upgraded my internet service at home in Australia to 500Mbps down and 40Mbps up on a FTTB solution. To achieve this, my ISP provided a dedicated NTU (being the Adtran 422G GFast NTU) that then plugged directly into the WAN port of my existing TP-Link AX-5400 WI-FI 6 modem/router that was also provided by my ISP. What I am wanting to do is to insert and OPNsense firewall on my NUC that has dual gigabit ethernet ports between my NTU and WIFI router which will be converted to a simple access point with the OPNsense NUC running all firewall, DHCP, and DNS activities for my network.
As can be seen in the attached OPNsense screenshot, the WAN interface is not being detected. The only things active (plugged in) on my network in the attached screenshot was my NTU and the RJ45 cable that went from it into the NUC. There was no downstream connectivity beyond the NUC and yet OPNsense could not see the WAN interface.
Any help here would be greatly appreciated.
