replacing Adtran 854v6

Hello,

I am having BeFibre installed and I have been told that they do not provide an ONT but an integrated ONT/router (Adtran 854v6), which is not great as I want to keep using my own network equipment and this might lead to double NAT (if I understand correctly).
However, I have read that someone was able to replace the Adtran 854v6 with an SFP Media Converter, would that be possible? I assume I would need the PPPoE credentials?

Thank you

Just replying to myself with an update that might help who is thinking of switching to BeFibre.
I have replaced the Adtran with a SFP media converter (i.e. TP-Link MC220L) connected to my router.
In order to connect to the internet I have set up the WAN interface type in the settings of my Synology router to "Auto" (I believe this should be DHCP) and added the VLAN ID. This can be identified in the routing page of the Adtran interface as the numerical part of the WAN.xx string.
(I must admit I was able to do all of the above only thanks to the help of other users)

All was working fine with exception of my webserver which I was not able to access anymore - I later found out that the ISP network was configured with CGNAT.
A few days after having contacted the customer support and explained my issue, I was assigned an external IP free of charge and all seems good now.
Wired speed tests are as expected, often in excess of 900Mbps up/down.

Thanks for the information Mike. I am also interested in using a SFP media converter (TP Link MC220L). What type of SFP module would I need to purchase a single or multi mode SFP module i.e. TL-SM311LS or TL-SM311LM.

Hi Richard,

I did not have to buy one as I simply used the one that was inserted in the SFP port of the Adtran router. I am not familiar with SFP modules and types of connections at all but I can provide you with the model number of the one I am using which is ADTRAN 1442535F3.

The connector is the one in the picture below, if that helps.

Regards,
celti

Thanks for that, I've got the Adtran Router two days ago so I suspect that the SFP module will be inserted at the bottom when the engineer comes to do the install.

Yes, the engineer will bring the module.
You simply need to remove it from the Adtran router and insert it in the TP-Link SFP media converter.

Hi thanks for this.
I'm also with Befibre and using one of the media converters which does seem to work well ,
How does getting a public IP address help with the CGNAT?
Can you remember what you said to them I might get in touch.
I have asked if they can provide the PPPoE settings but I've not heard anything yet and not sure they will do.
Thanks
 
My understanding is that if an ISP is configured with CGNAT, then your router is not going to have direct access to the internet but it will connect to another device owned by the ISP (another router?) which provide many users with only one external IP - this is done to limit the number of IPv4 addresses needed.
A problem exists if you want to access your own router from outside your network as the ISP owned device will not forward the incoming packets to your router.
I might be wrong but I imagine it as another LAN sitting at a level above my internal network.
When I contacted them, I simply told them I was not able to access my web server and after a couple of days they have assigned to me an external IP address, which in practice means I am not sharing one with multiple users and I can reach my router directly from the internet.

I am not sure how they assign the external IP to specific users, I think it might be associated with the mac address of the ONT/Router (Adtran in my case) so I set up my router to clone the one of the device I was given by BeFibre.
All is working now, I am not sure if the last step is needed though.

With regard to PPPoE, from what I read it is a different type of configuration which does not apply to BeFibre.

Cheers

Ah I see what you mean now, I've stopped using port forwarding altogether now but I'm still going to email and ask about that thanks .
What router are you using with it ?
I've been using a Draytek modem/router hooked up to solve Unifi switches and access points etc but when connecting BeFibre to the Draytek I've realised it has a maximum speed of 300mb so no good anymore so I need one to go with my Unifi devices ideally.

What router are you using with it ?
I have a mesh system made of a Synology RT2600ac and 2 MR2200ac connected via ethernet.
I have been using them for 3 years now and I can't complain, very good coverage and speeds.
Also the web interface is very well done.

Do you see 300Mbps when connected via ethernet?

Yeah that's with the ethernet which I don't understand as the specs say it's all Gb ethernet but then it's says maximum 300mb through firewall so I'm guessing I would have to disable the firewall which isn't ideal.

Thanks for sharing all this valuable information, you should be getting paid commission by BeFibre as without this I probably wouldn't even be considering going with them.

I'm currently using a Talk Talk GFast connection, which is decent but the upload speeds are average at best.

BeFibre FTTP connectivity has just been installed in my area. When they first appeared I asked them about static IPs and port forwarding as well as using my own router, after much back and forth they said none were possible at the time so I quickly lost interest.

I currently dont have a static IP, so I use a dynamic dns service (No-IP) as I host several game and media servers for friends and family. Looking at the above and whats been said on another thinkbroadband forum it seems as though theres now a decent workaround to use my own router to enable port forwarding as I'm led to believe this isnt possible on the adtran and despite repeated assurance that soon they will be releasing the linksys routers, they've yet to appear.

As I'd need to return the Talk Talk router, I'm thinking for picking up a decentish router like the TP Link AX5400. Everything else that I've read seems easy enough to muddle through to set up with my prior networking experience, however I just wanted to check if cloning the MAC address of the Adtran would be possible with this router, is it something that can be easily done? Its not something I've not previously done with a router.

I have done a quick research and found that tp-link have an actual emulator where you can try the web interface of various router models, really cool.
https://emulator.tp-link.com/ArcherAX73v2/index.html
password is "login"

If you navigate to the Internet page and select Dynamic IP as connection type, then it seems that you are given the option to insert a custom mac address and spoof the one of your ISP router.

I have used the model number Archer AX73 as it seems that it is the same as the AX5400, please double check before you go get one :)

I hope this can help
Cheers

Edit:
they might be a bit more expensive but based on my personal experience, I would suggest also considering Synology routers as they have tons of nice features and provide a free DDNS service

Hi there,

I'm with BeFibre but also having issues with the Adtran router. I want to change over to use my Deco as the router. Could you clarify how to get the VLAN ID please?

I've checked the routing page of the AdTran as you mentioned, and my WAN address is on the 154.61.153.0/24 network so is the VLAN 153?

I understand I will need to spoof the MAC address of the Adtran on the Deco settings as well as they MAC lock the network.

Many thanks.

Can you please confirm whether you have been configured with the Adtran as ONT/router or you have been provided with a separate ONT?
If you have a separate ONT (ethernet cable from the fiber termination box to the Adtran) then you do not need to use the vlan info I believe.
However, if you have the fiber directly into the Adtran then you need to navigate to the routing page and scroll down until you find a string "WAN." followed by a numerical value - that is the vlan.

The 153 you have found is part of your IP address and not the vlan.

If you are not bothered by the CGNAT configuration (you do not need to access your router from the internet) then you do not necessarily need to spoof the mac of the adtran.

I hope this makes sense.
Cheers

Thanks for the reply. I have the Adtran as the router and a seperate Nokia ONT on the wall so its just ethernet from that to the router.

I'm going to get in touch with them to sort the CGNAT thing out next week as I have a few things I need a proper IP for, but I had read that they are MAC locking the network and therefore may need to put the Adtran MAC in on my Deco.

All in all it seems to be a good thing that I have the seperate ONT and it may make it a bit simpler to swap over to something else by the sounds of it. I'll give it a try!

Thanks.

Does an online service show your public IP address is the one on your WAN?

What are the first three decimals of the CGNAT IP address?

The online service would show the shared external one if you are setup with cgnat.

I seem to remember my router was getting a 100.xxx.xxx.xxx address before I was given an external one
