Received Unifi ONR D-Link DPN-FX3060V.
TM Tech no idea about GPON bridge mode.
After they left, I followed instruction by eclectice for configuring GPON bridge and now back to using my own ASUS RT-AX86U.
VOIP is also working but need to enable back the proxy setting because it was disabled after changing to GPON bridge mode.
Haven't test the IPTV on my own ASUS router (LAN4).
Note: DHCP stopped working after changing to GPON bridge mode but luckily manage to login back to D-Link ONU router by connecting to LAN4 and manually set laptop IP to 192.168.0.x
