Just changed carrier router and pppoe is not working anymore

gabric098

I had a very stable pfsense setup with my carrier. As you can read in the referenced thread I use pppoe authentication to replace my carrier router, and everything worked great.
I changed house and my carrier installed in. my new house a new router. This is the exact same model as the previous, jus the username and password for pppoe are different.
I changed the settings updating the username and password and I tried to reconnect.
It doesn't connect and surprisingly I don't see any activity log under ppp section. It looks like it doesn't even try to connect.
The only thing "strange" is that the dpinger service is not working. It doesn't even start.

I'm a bit lost and I don't know where to start to look at for debugging.
Any ideas?

Your ISP gave you a new router and it doesn't connect.
Make that work first.
Only then it time to focus on pfSense.

Your connection is managed by the upstream (ISP) router. pfSense uses a DHCP or static IP on it's WAN interface.
Not some 'ppp' protocol.

..... or, do you have it all wrong ??? describe you ISP router.

using VLAN setup

Where does VLAN comes into play here ?

If it's really a router (not just a modem), you have to switch your router to "bridge mode" or "modem mode", otherwise it wants to do PPPoE on its own.

I apologize @Gertjan and @HG
I haven't added all the relevant information.
The ISP is providing FTTH connection. So I have an ONT and a router provided by ISP, 2 separated devices.
If I use the ISP setup, without pfSense, I have no problem connecting.
If I try to remove the ISP router and use pfSense, in the exact same way I was doing in my previous house, with the same ISP, it doesn't work (see my previous post for the details).

ISP setup:
ONT -> ISP router

My setup
ONT -> sg-1100 (pfsense)

My ISP uses pppoE authentication, so when I ditch the ISP router, I have to use a pppoe connection with a particular VLAN setup that is described in details in my old post https://forum.netgate.com/topic/148741/pppoe-using-vlan-setup

Apologize for not being more detailed in my initial post :)

Thanks,

If pfSense is the same.
If you would use the ISP modem / router - it is the same as the old house.
The ISP is the same.
The ONT device is the same ??
User login / password probably changed (new hous == new connection identification).

As you did in the other thread : it's time to sniff.
Like pppoe needs to send over some special ID ?

@Gertjan Thanks for the reply.
Yes, all is exactly the same, same ont, same ISP modem, same ISP.
As I said I've the new login and password. I had asked them to the technician and I also sniffed again to make sure they are correct. So, I'm 100% sure all is set up properly but, for some reason I don't see any activity in the ppp logs.
If there was an auth error, I would see a connection attempt in the logs, but I don't see anything, no activity at all... really strange.

Thanks,

Let me try this :

My actual setup is :

That is, I have a ISP router in front of my pfSense. This router has the famous config : an AP, a switch, a router, a firewall, and a VDSL modem all in one. Because the VDSL is ISP specific, I can't change this ISP router for a ordinary off-the-shelves VDSL modem, which will permit me to use PPPoe.
( no "PPP" because that one asks about phone numbers etc )

I set my access to PPPoe, set a user and password and Save / Apply.
Now, of course, my connection is totally broken, but I do see log lines on the PPP log page :

@Gertjan thanks for trying that out.
Eventually, I've restored a pfsense config backup since 1 month ago. I changed the password for pppoe and now it just worked.
I still don't know what I did wrong the first time I tried but the important thing is that now I have pfsense correctly configured and working.

Thanks for the support!
