Hello,

I had my connection changed from DSL to FTTH and Airtel gave me a Nokia router. The model comes with the following WAN config,

Under WAN settings I created a new connection with IPOE mode and same VLAN 100,

Also I changed the port 4 to Bridge mode.

The router restarts at this point. Port 4 blinks momentarily blinks on bootup but then stops detecting the LAN cable. It seems that the port gets disabled. The Ports 1 and 2 however do remain up when set to bridge mode.

@napsterX The solution in this post doesnt seem to be working for this model.

Following is the screenshot from my Huawei EG8145V5 router which is setup in bridge mode. Comparing this with Nokia router configuration, it seems we are missing the option 'Bridge Wan' under 'WAN Mode' in the Nokia router.

Also, notice that connection name in the HUAWEI router '2_Internet_B_VID_10' is similar to the Nokia router ('2_Internet_R_VID_100'). The 'B' in the name refers to bridge while 'R' in Nokia refers to routing. Maybe the 'Bridge' option in 'Wan mode' is actually there but not exposed in the Web UI.

The usermanual for G-240W-F shows similar UI to this router.

The router sticker looks like so,

The router/GPON has a telnet interface. Unfortunately, the console does not provide a facility to configure the router,

Internally it is running the same software as G140WC,
Code:
user(show)# buildinfo
ONT_TYPE=g140wc
PON_MODE=GPON
SOFTWAREVERSION=DGA.B98p01
PRODUCTCLASS=g140wc

CVP_REVISION=3d58ea3594f91a6b91a25ed4c0017b754f08d4b3

There seems to be and old config in the router,
Code:
user(show)# swversion
Software Image #0:
version = 3FE47150DGAB98
is active = Yes
is valid=Yes
is committed =Yes
Software Image #1:

Did anyone find a way how to do this? I am thinking of an alternative but I don't know how effective its going to be.

My idea is to connect my 2nd router (R2) to the Nokia (R1) one, R2.WAN->R1.LAN, assign R2 a static IP, set up DMZ in R1 to that IP and then use R2 for all my devices/computers. I will switch off the Wifi and other stuff on R1 (there is a button for wifi on/off). I ordered the TP-Link Archer C6 for its OpenWRT support and will get it in a couple of days.

I think this idea somewhat solves the double NAT issue but, I would prefer the Bridge mode!

Also, if in theory, lets say the bridge mode thing starts working, how do I get the login credentials for the PPPoE connection so that I can set it up in my router?

Yes, the DMZ method works. I tried it with the Nokia router.

The pppoe username is visible in the Nokia router settings, while the password is simply your account number. You can get that from Airtel.

I ended up buying a Huawei HG8145V5 router from OLX which had bridge support and got rid of the Nokia router. Problem with running a closed router like Nokia is that you are dependent on Airtel for firmware updates. Using Openwrt or pfSense is way better since, these are updated regularly.

@rajil.s Thank you!

I was just searching around Amazon and found ONUs like this

Can I use them as a bridge between the OFC termination and my own Router, eliminating the Nokia one completely?

What do you think the chances are that Airtel is gonna give me a bridgeable router or an ONU if I ask them? I am still waiting for my TP-Link Archer c6 to come.

Finally, how much did you pay for the Huawei HG8145V5 ?

Airtel will not let you use off-the-shelf ONU. Their backend has some sort of software which recognizes only few router types. Theoretically, it is possible to use any ONU but their backend staff is not that competent or don't want the hassle of configuring manually.

Buying a Huawei router yourself is the best option. If you don't want to go down that path then another alternative is to ask for an old Alcatel router model I-240G-D. It is in bridge mode out of the box. The downside with this is that the webui username and password is not known to anybody. It doesn't exist in Airtel system but they do provision it. You may have a hard time getting it from your local Airtel technician as it is an old model. No wifi on it though but does support telephone line.

There are lot of people on olx selling Huawei router, price depends on your negotiation skills :)

Hi rajil.s,

Can we just replace the Nokia ONU with Huawei ONU (from another Airtel customer). Is the ONU locked to a customer?

Does Airtel has to change from their side anything if we replace from Nokia to Huawei ourselves?
