PPPOE - Traffic shown on all wireless bridges

Hi there,

I’ve an Access Point Wireless where several clients are connected .

Each client connects to Internet using PPPoE client of Mikrotik 2.9.40 CPE, to a PPPoE Server on a server on our office.

Configuration for each client is :
src-nat pppoe-out masquerade

The problem is that just one of this client shows its traffic over all the wireless bridges till the PPPoE Server, like if PPPoE doesn’t exist.

Just this client, which has the same configuration of others, shows all the traffic using the IP provider from PPPoE pool while others don’t as they just show traffic on PPPoE client and PPPoE Server

It seems very strange, and I’m going to change hardware to solve, or reinstall routeros.

Any opinion ?
