PPPOE connected but no Internet

Installing and Using OpenWrt
1

Hello friends, I hope you can help me with the following problem. Sorry for any errors, English is not my first language.

I have OPENWRT installed on a mikrotik rb750gr3, which has worked excellent for me along with mwan3 and pbr. I have two ISPs.

We recently installed a fiber provider, so we decided to remove our second backup (ADSL 4mbps). However, since day one, we have not been able to use the connection.

PPPOE authentication works correctly, I am assigned a public IP address. Using tcpdump I have been able to see that the authentication works correctly, however, I cannot ping anything, including the gateway.

Currently my router is configured as follows:

Captura de pantalla 2023-12-29 180938
Captura de pantalla 2023-12-29 180938614×530 105 KB

As you can see, the authentication works correctly. The 5 packets that appear are authentication, but from there, no further response was received.

Using "tcpdump -e -i pppoe-wan2" while pinging, I can see packets going out but get no response.

Using "tcpdump -e -i lan2" while pinging, I can see some others packets and I do get a response on "lan2" but on "pppoe-wan2" I get nothing.

My ISP has confirmed that they do not do any type of blocking for MAC. They told me that they can see that the packets are "flowing", but they also cannot ping my router, since they "have no response."

Do you see anything wrong with the /etc/config/firewall file?

I don't see anything wrong. I even "allow" everything, just in case.

I think you need someone more experienced than me, sorry for the wasted time

ps I apologize for having entered wan2 I only read after you had already tried and the packets seem to go out but not in

What is VLAN 804 ?

ok I think you're right as usual (that's why you know everything) :+1: :grinning:

but why can she get an IP address,

dhcp packets are not affected by vlan (just for understanding)

9

My ISP configured that VLAN on the ONT before configuring it in bridge mode.

10

Then you probably need to do the same on your side.
The fact that you see the tagged frames tells that your interface needs to be tagged as well.

11

How I do that?

Thanks!

12

minimal support (from me)

and again sorry for the wasted time :sweat_smile:

I don't have any PPPoE and/or VLAN setup around me now, so my guess it should be something like

config device
        option type '8021q'
        option ifname 'lan2'
        option vid '804'
        option name 'lan2.804'

config interface 'wan2'
	option proto 'pppoe'
	option device 'lan2.804'
	[all other stuff]

I've updated the example above, please give it a try.

Nothing, it wont connect.

Here is the ifstatus wan2

ifstatus wan2
{
	"up": false,
	"pending": true,
	"available": true,
	"autostart": true,
	"dynamic": false,
	"proto": "pppoe",

	"data": {
		
	},
	"errors": [
		{
			"subsystem": "pppoe",
			"code": "USER_REQUEST"
		}
	]
}

If i remove "vlan 804".

Is that "route" ok?

18

Your [default] route is absolutely fine.

19

Ok. I've tried connecting the ONT into a laptop and the Internet works just fine.

Tried connecting the ONT into a Deco X55 router, no internet.

20

Did you configure pppoe on the laptop or just make a connection with its default DHCP connection?

ONTs can be configured to add/strip vlans and also decapsuate pppoe and send regular IPoE (conventional Ethernet) packets to the user's router. So it's important to know exactly how the ONT is configured.
