Cannot pppoe if not connected to the bridge of provider's mikrotik

my italian provider open fiber just installed in my rack a new optical fiber GPON connectivity.

They passed into my office’s walls an optical cable that ends into a zte zxhn f601 converter sc to rj45. Then they connected the zte to the wan interface of a basic mikrotik router board hEx lite.

From this point they gived to me pppoe authentication parameters, pppoe ip interface and a network of 8 static ips that I requested into the contract. To make a successful pppoe connection, I need to connect the second port of the hEx lite mikrotik to the wan interface of another router(in my case is a mikrotik too but this one is an enterprise version) and this is working perfectly. The point is that I want to find a way to remove this hEx lite mikrotik from my environment. Considering that I tried to connect directly with pppoe parameters from my enterprise mikrotik connected to the zte without success, I’m trying to understand what they have done on their hex mikrotik side to make it works. During the Installation I asked the technician if this hex mikrotik was something like a pppoe server from my side or if is taking a specific ip only for the monitoring. He told me that wan port and lan port are bridged and there is no pppoe server, they simply create a separate connection only for monitoring. So at this point I’m sure that I’m connecting directly to the outside with my enterprise mikrotik but for some reason if I’m not connected to this bridge the connections fails(there is no authentication error, simply it trying to connect without success) so I’m asking you were do you think the lock is, and what I can do with my mikrotik to overcame this. Many thanks

Why change it, if it works and you get your full speed, leave it and allow them to monitor the link.

Then as to why, they probably have vlan config on the hex

yes exactly, it’s just to understand how it works .. o you think that having such a small device behind such a large system (8nodes cluster, 60 workastions, very stressed sql vpn web server etc) will somehow kill the performance of this small device?

What speed line did you get?

1ms 1000mbs down 500mbs up.

do you think there is a way to retrieve the vlan id of the provider analyzing the traffic?

If info in post above is accurate, then you can’t get 500 up as all interfaces of hex lite is 100 mbs

I’m sorry this is my mistake, I didn’t notice that there are two versions so I picked up the first one, is the hEx version not hEx lite for sure, I checked it now.

I found that the vlan id was 835 so I created a new vlan interface and added it to my pppoe setup, now is warling perfectly!! thank you so much for your suggestions
