PPPoE User Suddenly internet is not working even user is connected
Hi All, One of my clients is complaining to me sometimes, a pppoe user suddenly showing no internet at the user side but the user is connected with mikrotik pppoe server.. when he disconnects it from mikrotik and after re-connection, that user's internet is working fine at the user side.. So, is this related to the radius accounting response or something? Because this issue is not there when he is connected to a local user which is created in mikrotik without radius. Thanks Imdad
Once a user is connected, Mikrotik doesn't keep any concern with Radius for browsing related things. it's all about network . Regards Vijay A. On Sat, May 27, 2023 at 1:56 PM Imdad Hasan <imdadalikadiwala0@gmail.com> wrote:

Reduce idle timeout to default ppp profile to remove the idle users. On Wed, May 31, 2023 at 1:20 PM Vijay A <vijay.hcr@gmail.com> wrote:

Most likely you are having routing problems. User gets IP from dynamic pool. When user gets IP address from address block that is wrongly routed he will not get internet access. After reconnecting he is mostly likely getting address from correctly routed address block and everything is fine. Maybe it's a good start to check your ip pools on pppoe concentrator and routing for those address blocks. Igor On 31.5.23. 09:49, Vijay A wrote:

This is common in ISP networks as I have seen similar issues myself. It has nothing to do with freeradius. The issue is PPPoE is a jitter sensitive protocol and the connection becomes zombie if there is a small jitter in the network. Once the session becomes zombie , it looks like the user is connected but there is no traffic between the user & NAS. To tackle this, 1. Avoid Jitters 2. Disconnect User in 24 hrs timeframe. 3. If PPPoE clients are icmp reachable use a watchdog script to remove session if unreachable. Regards On Wed, May 31, 2023 at 1:28 PM Igor Smitran <sigor@blic.net> wrote:

Staled sessions should be cleared by pppoe concentrator based on LCP probes. LCP probe every 30 seconds. If 3 LCP probes fail than clear virtual interface. I think every modern pppoe concentrator has this capability included (including Mikrotik). There is no need for additional scripting, making system more complicated than it is currently.
