On a practical level, having the stupid ONR breaks a lot of things like VPN tunnels to work As the text is a bit small, I shall replicate it The arrows remain TOP Diagram (Arrow pointing to ONR): SingTel has full configuration access to this one device
Using Router behind CGNAT, behind ONR (Double NAT), ONR bridging, ONR . . . 3 Potential work-around for ONR and avoid Double NAT -- ONR replacement with ONU or PON Stick 1) So far there are only success stories for ONR replacement Singtel WC GPON ONR You can check them out in this thread and the linked posts Here is an thread using VSOL V2802RH to replace Singtel WC GPON ONR

Optical Network Terminal (ONT) vs Optical Netork Router (ONR). Whats . . . But before March 2022, it was at least possible to request bridging of ONR for users who want to use their own routers (not only power users, but also other users) After that, SIngtel no longer entertains bridging of Singtel ONR, the only officially bridged ONR will be reserved for the niche Singtel 1+1 Gamer Bundle plan

Using Router behind CGNAT, behind ONR (Double NAT), ONR bridging, ONR . . . BTW, there is also no successful report of using other XGS-PON ONU to replace the ONR used by Singtel WC or the ONR used by Starhub On the other hand, there are quite some successful stories of using GPON ONU to replace the GPON ONR used by Singtel WC So I guess XGS-PON ONR may be more difficult to replace than GPON ONR
