Using Router behind CGNAT, behind ONR (Double NAT), ONR bridging, ONR replacement with ONU or PON Stick

What is your question? Why do you need to use pm? I really do not understand why people want to use pm for technical questions. In fact I do not answer technical questions using pm. pm is mainly for non-technical questions like lobangs.

My template reply to such pms:

Sorry I do not answer technical question using pm as my answer may be wrong or biased and then no one can correct the answer if I use pm to reply.

Please post the question to the correct forum section and I will be happy to answer in the forum. You can even PM me with the link if needed.

Hi xiaofan.

Completely agree, technical questions should be shared. My question is about how to access the superadmin interface on the Nokia G-240. Other posts on this topic clearly say that credentials for this device will not be posted on the forum. Hence the request for a point in the right direction to find it, or a PM so as not to violate the credential issue.

I thought I was replying directly to Matt_Max’s request for the same, but must have replied to the forum and not the post itself. Hope this clarifies

As per the report, Nokia G240 GPON ONR super-admin login info is the same rule as the ZTE F620 GPON ONR. It is mentioned in Post $71 of this thread.
Username: support
Password: the password printed on ONR label but need to input in reverse order.

You can try it and update here whether you got the success or not.

More info about Nokia G240 ONR super-admin login info -- please try the following, which is similar to ZTE F620 ONR.

Username: support
Password: the password printed on ONR label but need to input in reverse order.

Oh I thought the login password is given to user by default, since I requested during ONR installation and SingTel installation technician shared it with me.

From my case,
Username: support
Password: the password printed on ONR label but need to input in reverse order.

You may test but not sure if it works on your ONR.

Initially I did try set LAN port to bridge mode but it didn’t work, then I realised that I need to create a new connection in WAN setting in bridge mode and assign the bridge connection to a LAN port, in my case I assigned LAN port 4.

There is risk if you setup wrongly. In my 1st trial I set all 4 LAN ports to bridge mode but after that I found I was blocked out from the ONR and no longer able to access login page via 192.168.1.254 on any LAN port and no internet access as well. After that I did hard reset the ONR by reset button, the internet is back under normal ONR mode, but digital line gone. I called the installation guy and asked him guided me setup digital line, then I tried to bridge the ONR in WAN setting as above mentioned and finally got it work.

I will terminate SingTel 1Gbps plan next week and move to M1 1+1Gbps plan. As you know SingTel ONR is not friendly to power users.

1. I also believe it is per GPON connection (either GPON or XGS-PON).

2. The only strange point is related to ZTE F8648P XGS-PON ONR after bridging one port (usually the only 10G LAN port). Even though the ONR (with four unbridged 1G LAN ports) keeps its public IPv4 address (as well as IPv6 if you have got Singtel to enable native IPv6), devices connected to the unbridged ports can not access Internet. It is said that Singtel TV Box will work when connected to the unbridged LAN ports.

As per earlier reports, the unbridged ports used to work previously. Later some changes in ONR FW version and Singtel side somehow caused the above changes.

3. This behavior is actually very much the same for officially bridged Singtel GPON ONR for 1Gbps customers (when Singtel still entertained such bridging requests) --> only the bridged port has internet access. The remaining unbridged ports do not support internet access -- you can only connect Singtel TV box to the unbridged ports.

This makes sense. The bridged port already supports 1Gbps bandwidth. If the unbridged ports have internet access, the total download bandwidth may be higher than 1Gbps.

4. On the other hand, when users of Singtel 2Gbps/2.5Gbps and WC 2.5Gbps bridged one port of the ONR by themselves (not supported by Singtel/WC), the bridged ONR LAN port will have access to Internet, the other unbridged ONR LAN ports will also have internet access (as well as using Singtel TV box). Basically this behavior is very much similar to the official bridged Singtel GPON ONR for the Singtel 1+1 Gamer Bundle plan.

It kind of makes sense as well --> the brigded port has only 1Gbps bandwidth, so the unbridged ports need to have access to internet to support 2Gbps or 2.5Gbps total download bandwidth.

Hmm I don't understand your point 3 and 4.

The download bandwidth is still constrained by the fibre optic connection ultimately, not the bandwidth of each individual ethernet port on the ONR. The physical layer is constant, despite more network connections by virtue of more IP addresses allocated.

It is okay, the reason why the behavior is just my guess.

Anyway, for Singtel 1Gbps ONR official bridging done by Singtel, the behavior is as what I mentioned --> bridged port is working for internet access and the other unbridged ports have no internet access.

For Singtel 2Gbps/2.5Gbps plan and WC 2.5Gbps plan, if you bridge one port, the behavior is as what I mentioned --> bridged port is working for internet access and the other unbridged ports also have internet access.

I was unlucky as my previous bridged nokia ONR suddenly no internet but PON is ok. Singtel send technician down to replace the ONR to ZTE F640 and insist that no bridge mode can be done.
reading the forum again saw the login to do so. Tried but unvail. I need to use it with my gt-ax6000 but hate to have double nat. Also my singtel tv need to connect to onr directly. So wonder if the single port bridging still works? I can seems to get it to work. Asus shows connected but no internet. Best now is to put asus ip to dmz in zte.

You mean to say ZTE ZXHN F620 GPON ONR, right? No F640 model.

Are you using 1Gbps plan or 2Gbps plan?

By right single port bridging should work. And SingTel TV box must be connected to the ONR unbridged port, as the bridged port only works with Internet and not for SingTel TV.

Maybe you want to post the steps and screenshots of how you perform the bridging.

 

[mik385]

thanks for the quick reply!
Yes typo. ZTE F620

I did a factory reset then set the lan1 to bridge. And then connect to the asus router and then restart the router. On asus router it shows connected but the internet connection was only work abit in the start then it can’t work any more.

Restart the ONR and the router and see if that helps.

By right you should not factory reset the ONR. If it does not work, I guess if you have to ask SingTel to help to recover. Or go to the shop to replace the ONR.

Did you record down the ONR configuration before the factory reset?

 

[mik385]

seems like the settings will push down after factory reset. Anyway I did factory reset is after many tries of failure then saw a post here that they reset hence I try also. Anyway it work after factory reset just that once it bridged, the network will connect but when down immediately.

 

[mik385]

Tired of endless tries to bridge single port. Back to escalation with singtel else I can’t get my Asus be the main router for vpn, ddns, port fwd….. dmz on onr seems not working too

Not sure why when the single port bridge is done, from Asus Side all is like normal. Wan ip is detected as well. Just that no internet. I am guessing that Singtel side have to do something?

If bridging is successful, by right Singtel side does not need to do anything. If Singtel side needs to do anything, then you cannot bridge by yourself.

Maybe you want post the screenshots how you carry out the bridging.

If not bridging, then you have internet access, right?

The worst case scenario is that Singtel side has done some changes on the backend or the ZTE ZXHN F620 Firmware, which makes the bridging not possible.

Same for the Singtel XGS-PON ONR (ZTE F8648P). Previously it was easy to bridge, then suddenly in August with the new FW version, it started to have problems. The problem is that some people can bridge and some cannot. The symptom is that the user will immediate lose internet access once click to bridge one LAN port of the ZTE F8648P ONR.

It took me more than two months before I could bridge the Singtel ZTE F8648P XGS-PON ONR.

One more question, your Asus side does work after the briging. What about the remaining three ports not bridged? Are you able to access internet when you connect your computer to the unbridged ports?

The reason I asked is that for the ZTE F8648P ONR, the bridging behavior also changed. Now only the bridged port works for internet, the other LAN ports not bridged cannnot have access to internet, even though the ONR itself still have access to internet based on the diagnostic function (ping still work), just not the LAN clients.

Another post which mentions the bridging method of Nokia G240 ONR here.
https://forums.hardwarezone.com.sg/...ngtel-nokia-onr-to-bridge-mode.6373260/page-4

I logged in with the technical support account, bridged the WAN and LAN ports together, and configured my own router's VLAN ID to 10 to achieve bridging.

sorry for the noob question, is M1 ONT automatically in bridging mode? ( for both the old 1G and new 2.5G). also interested to get rid of the ONT completely, still researching on it via @xiaofan ’s multiple sharings

also, if i get a router from china, it would work natively just like the asus router given by m1 i suppose? unlike singtel who only allows its own router to work and have to go for double Nat

ONT --> bridging mode.

In general, you do not need to replace M1 ONTs as it does not pose any limitations to the user. M1 does not use ONR.

M1 500Mbps/1Gbps plan --> ONT has one active 1G LAN port
M1 2Gbps plan (dual 1Gbps plan) --> ONT has two active 1G LAN ports
M1 2.5Gbps plan --> ONT has one active 2.5G LAN port
M1 3Gbps/6Gbps/10Gbps plan --> ONT has one active 10G LAN port

 

[xiaofan]

Yes for M1.

Singtel ONT (only for legacy 500Mbps/1Gbps plans) --> you can use your own router as long as it supports Singtel VLAN

Singtel ONR (unbridged) --> you have to set up your router in bridge mode to avoid Double NAT. Or you have to live with Double NAT if you want to use your own router in router mode.
