[Help Needed] Airtel Nokia G-2425G-A Bridge Mode Issue – No Internet on MikroTik (PPPoE on VLAN 100)

[ghostiin]

So, Yesterday, I requested Bridge Mode via the Airtel Thanks App, and a ticket was created. Today, a technician visited, called someone, and told me it would be enabled by evening. By then, Ports 3 & 4 were switched to Bridge Mode, but I'm still facing the issue.

I’ve connected my Mikrotik router (ether1) to LAN 4, added VLAN 100, and configured PPPoE with my Airtel credentials. However, my MikroTik’s PPPoE client is stuck at "Waiting for Packets" and refuses to establish a connection.

Observations & Troubleshooting So Far:​

Bridge Mode is active on Ports 3 & 4 in the Airtel router’s settings.
LAN 4 LED blinks during boot-up but fades as soon as the Auth LED blinks.
The ethernet cable is tested and working.
Tried manually setting VLAN 100 on MikroTik
Configured PPPoE on VLAN 100:
Tried disabling VLAN 100 on MikroTik and using ether1 directly, but no luck.
Checked MikroTik logs, only shows PPPoE discovery but no response from Airtel.
Change Router to a TP-Link shows WAN Port not Connected.

Do Any of you Guys Know:

1 Why does Bridge Port Lan Led stop blinking after authentication? Is this normal behavior for the Nokia G-2425G-A?
2 Is there a known fix or workaround for this issue?

AFAIK the Nokia G-2425G-A adds/strips the VLAN 100 when the packets are sent or received over the fiber cable, but on the LAN port side of the Nokia the packets are untagged.

Hence you need to remove VLAN from Mikrotik settings and leave it untagged on the WAN port of Mikrotik.

Regarding Bridge Mode itself, I read that sometimes it takes effect only after a reboot or power cycle of the Nokia G-2425G-A device.

Tried without the vlan tagging. Also tried with another router (TP-Link) still link seems down
