Hello,

I had analyzed my log file and found that my PPPoE connection are dropping on a daily basis. My log file with the applied filter is below.

How to configure PPPoE interface to stop doping connection?

Current config:

/interface pppoe-client
add disabled=no interface=ether1 keepalive-timeout=disabled name=pppoe-out password=*** use-peer-dns=yes user=***

Now I’m sure on 99% that connection is dropping on the ISP side. Because radius_default_session_timeout by default is 86400 seconds. I believe that it wouldn’t be changed because of if the billing period is over then the session will not be interrupted. And I will be able to use Internet with the $0 on my account.
