Unable to get bridge mode working on a Chinese ONT

[jefff]

Hello, I have a Chinese ONT (does not have brand name, web UI just says SMART HOME GATEWAY) which supports bridge mode. But I'm unable to get it working with my TP-Link router. Here are the steps I followed:

1. My ONT is having IP 192.168.1.x, TP-Link has 10.0.0.x IP series and connected to LAN 4 of the ONT. I changed the mode to bridge mode on ONT. Screenshot
2. Navigate to TP-Link admin page and clone the MAC of the ONT.
3. Change the connection type to PPOE and entered the username and password like this. (Screenshot of advanced settings)
4. The TP-Link ppoe page is stuck in connecting stage. These are the logs from the TP-link router -

disable dhcp server but first take a note of your credentials

likely the ONT does not actually support bridge mode. You also have vlan tagging on, ensure that is correct.
Don't bother cloning MAC; just ask your ISP to reset the filter.

I have disabled the DHCP option in ONT.

likely the ONT does not actually support bridge mode.

The ONT UI has an option to set it as bridge. I don't know about the VLAN config.

Still the ppoe is in connecting status

Could u undo your setup and do ppoe auth on ont this may help troubleshooting

Btw which isp u using

My ISP is BSNL. If I revert the config and enable the route mode instead of bridge mode in the ONT it successfully connects to the internet. The links status is also pretty good.

You have to use VLAN ID in the router. Is there an option to add VLAN? Also, what model is the router?

With some of the Chinese onts you just need to delete all the WAN configs including where your pppoe details are specified and by default it goes into bridge mode.

It's a TP-Link Archer AX 53 WiFi 6 router. And it does have VLAN option I guess

Edit: These are the VLAN options available

I tried to copy the VLAN info from ONT to my router but it didn't work. Here are the info:

Tp-link PPOE config
Tp-link VLAN config
ONT connection

But the PPOE is stuck in connecting state, here is the route logs
