Hi everybody,

I have configured on same mikrotik router (CCR1016) a pppoe server and radius server.
The issue that I have encounter is, the packet size accounted in radius is higher than sent.
Thus, I would like to get correct value of upload/download for my clients.

Topologie:
PC1 (client) -> Router mikrotik (pppoe client)-> Router (pppoe server + user manager radius)-> PC2 (server)
Eg: using iperf3, I send 1Mo from PC1 to PC2, then I got 1,9Mo on accounting.

Below is the configuration on NAS:

/ip dhcp-server add disabled=no interface=sfp1 name=dhcp-1 use-radius=yes

Thank you for help.

Any help please?
