Can't port forward without UPnP?

[Realme]

Hi ! since the internet came back I'm facing a weird problem(and after ONT update)

Setting up manual NAT settings on ONT achieves nothing but the moment I open UPnP(I don't want to do this) , Port forwarding work fine

Also a new settings are introduced in Network>Internet tab : NAT configuration, it allows to specify NAT level(I tried all combinations)

Are you guys facing the sma trouble or we are behind some weird NAT by BSNL after the BOTNET attack?

Please use these useless ont's in bridge mode and get yourself a good router.
I think they're trying to block outbound and inbound connections to try prevent botnet attacks as the firmware update has come based on BSNL's insistence.

Claps to BSNL team for allowing UPnP forwarding but not mannual NAT , well LCO sold me it for 2000 so no budget for router right now but I will wait for good router with PON ports compatible with BSNL

Why do you need a new PON port router? Just use your existing ONT in bridge mode, connect it to a router. Problem solved.
