Using custom (raspberry pi) openwrt router with BSNL FTTH question.

[simon.george]

Hello,

I am from Kerala, and using BSNL FTTH.

Current setup is,
Bsnl non branded ONT device which got a fiber input and 4 ethernet ports.
Ethernet port 4 of above ONT is connected to TP-Link AC1200 router uplink
And in router WAN is configured with ppoe username and password.
Everything works.

Now I would like try a custom build openwrt router with raspberry pi 5 (to replace Tplink router)
I connected port no 2 (I first verified that port no 2 works by connecting to TPLINK router) from BSNL ONT to raspberry external USB to ethernet adapter.
Raspberry pi built in LAN to my PC.
Configured the router WAN port with ppoe and same username and password.
But, ppoe connection is not successful. I see errors like AUTH_TOPPER_FAILED, CHAP AUTHENTICATION NOT SUCCESSFULL etc.

Any one done this kind of setup?
Is there a management page for ONT device? What would be the ip address of it?

@simon.george typically it's 192.168.1.1, but you can check the back of the ONT or check the default gateway through ipconfig /all
Also, you need to bind the specific ports when using bridge mode

Yes ONT device ip is 192.168.1.1.

What I tried, I connected LAN port of my windows 10 PC directly to ONT port 2 (which I earlier tested and confirmed works by connecting to router normally)
Then did an ipconfig in windows 10,

Connection-specific DNS Suffix . : local.lan
IPv4 Address. . . . . . . . . . . : 192.168.1.6
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.1.1

However 192.168.1.1 is not pingable (may be ICMP disabled) or no web page runs on 192.168.1.1

Then I tried setting a ppoe dialer in windows using the ppoe credentials setup in my router. But getting error number 691.

I wonder if the ONT will authenticate ppoe only with my TP-Link Router WAN port, because BSNL whitelisted it?

@simon.george in that case, a MAC flush is required. Kindly ask BSNL to flush the MAC.

 

[simon.george]

Thank you.
Do you think if they can whitelist multiple MAC address? For eg, MAC address of TPLINLK router, WINDOWS PC and my new openwrt router?

 

[IfranAli]

@simon.george NO, only one can be done

@simon.george You can access the ONT via Raspberry Pi by simply adding a route [OpenWrt Wiki] Accessing the modem through the router

@simon.george I am using OpenWRT in Raspberry PI as router , with a Huawei ONT in bridge mode. All works okay here.

I believe you have selected the USB to Ethernet adapter as the WAN port in OpenWRT. If that's the case you need to clone the whitelisted MAC to this interface.

Login to BSNL selfcare webpage and see the broadband connection history , you will get the whitelisted MAC there.

Thank you for the suggestions, what would be the BSNL selfcare webpage for south (Kerala) BSNL CUSTOMER CARE does not have Kerala in the zone.

@simon.george There is a app by BSNL .
BSNL ecare. It's currently unavailable in both play store and app store .
