No connection with PPPoE and VLan connection

stephenw10

So that's with the modem/ONT in a different mode?

I would not expect to be able to make two PPP connections on the same WAN.

I would not expect to be able to connect directly to the modem without using PPPoE unless it's running as a router.

Do you have access the modem/ONT to see how it's configured?

No, some parameters of the modem/Ont connection are blocked by the ISP and not visible. I wanted to unlock the modem, but I couldn't find the necessary instructions. What is strange though is that the ISP has stated that it is possible to make up to 5 PPPoE connections from the same ONT.
Question: is it possible to use the same VLAN on multiple connections?

This is the only visible thing about the connection:

Hard to say. I wouldn't expect to see more than one PPP link at all. But you appear to have at least two running there.

If you disable the PPP link in the 'modem' does pfSense still connect? Does it change the upload rate?

I disabled the PPP connection, but no other connection (WAN or WANTIM) worked. It is as if, without the modem connection, it is not possible to make other connections. Strange thing...

stephenw10

Hmm, this is strange indeed.

I guess I would be looking for other users of that ISP who are using 3rd party routers.

If I can find a way to unlock the modem/ONT (Technicolor DGA4331) maybe we could figure out what strange settings it has inside. Anyway, thank you for your interest.

stephenw10

Is it just one device that is upstream or is there a separate ONT and router provided by TIM? Other similar threads for other routers seems to suggest it's separate. In which case bypassing the router part would be what I would try.

TIM only supplied me a Technicolor DGA4331, a modem router that I use (I would like to use) only as an ONT. Do you think that if I eliminated the 4331 and connected the fiber cable directly to an ONT or to Netgate 4100 the problems would be solved? Unfortunately I don't have an available Ont to test this solution now.

Hmm, interesting it looks like that device has a removable SFP module that might indeed work in the 4100 directly. My Italian is.... not good though! I can't see exactly what it is. GPON?
You would lose the phone connection of course.
That shouldn't be required to get full throughput though.

On sight it looks like a removable SFP module, but I can't take it apart because I'm not the only one using internet now, I'll do this test tomorrow and let you know. See you tomorrow.
Thank you.

Hi @stephenw10 ,
I just removed the SPF module from the TIM modem

and I mounted it on the combo port of the Wan. I tried alternately enabling the two previously created WAN configurations (WAN and WANTIM), but no connection came up. I looked in the Netgate GUI menu for anything that told me that the inserted module was active, but I have no evidence that it works. I don't know if I have to activate it somehow, install some drivers or something else, for me it could also be turned off or incompatible. Now I had to insert it again in the TIM Modem, but I intend to do other tests later.

stephenw10

Hmm, that's interesting. It may not work in other devices. Those modules can be very fussy!

The first test would be to put it in one of the SFP ports on the 4100, say WAN1 (ix3), then run at the command line:

ifconfig -vvvm ix3

That will show data from the module if it's able to read it.

Using the SFP module directly in the 4100 would be really nice solution but it shouldn't be required to get the full bandwidth.
You might check for errors in the interfaces in Status > Interfaces when it's showing only 20Mbps upload.

No way, it just looks like it's turned off. I found this photo on the Web where you can see that the LEDs on the WAN port light up even in the presence of the fiber connection only,

but in my case the LEDs stay off.

In response to Status > Interface

the interface appears as if it were turned off.

This is the list that came out in response to the command you asked me (address are modified):

I don't know if there is a compatibility list for SFP modules, probably the 4100 needs an internal driver for this one which is not installed. I don't know what else to try.

stephenw10

There's no driver you could use here, it may just not be compatible.

In that photo though the link LEDs for ix3 are lit. Which is interesting.

Reviewing though the ix combo ports won't show the module info which makes this inconvenient. It should show linked though if it could work.

I read about MAC spoofing for WAN PPPoE connections and I need to try it, but MAC address field does not appear in the WANTIM configuration window. I also read that the MAC address for spoofing must be entered where the parent interface (ix3) is present, but also in the WAN configuration window the MAC address field does not appear. Where am I wrong?

Airone 0

Solved MAC spoofing problem. I've printed you a picture of my dashboard in case you see anything strange. I'm about to give up, I don't know what to do anymore.

stephenw10

So how it that connected right now?

What's working or not working?

The gateway passed by PPPoE may not respond to ping so you might want to set an external monitoring IP like 8.8.8.8.

Hello @stephenw10 ,
now the 4100 is connected to the ISP's modem/Ont again, that's the only way it works even though I have limited upload speed. I also saw that there are problems with the gateway, but I can't figure out where to make changes to fix it.

However, everything seems to work without problems, I don't see where the above problem could affect.

stephenw10

Set a different monitor IP in System > Routing > Gateways > Edit the WAN_PPPoE gateway.

Already done, thanks. But now I will try to unlock the Modem/ONT in order to read its settings or I will look for a compatible SFP module to use the same 4100 as ONT. I don't see other possibilities. If you have any other ideas, welcome.
Thanks anyway for the assistance you have provided me.
