Hi Everyone, I've recently upgraded from Ubuntu 22.04 (Jammy) to 24.04 (Noble) and encountered a HIGH CPU usage issue caused by networkd-dispatcher when it interacts with the PPP interfaces created by ACCEL-PPP. I've attached an example from htop. When I check the logs in journalctl, I see errors li...

Hi @dimka88, I experienced the same routing issue this morning. According to the log, a session was destroyed, but the connection's IP route remained in place. The session then came up on another LNS, causing a routing problem. I believe the issue occurs when the interface is renamed. The renamed in...

Hi @dimka88, Thanks for the useful inputs. I had to switch the debug level to 4 from 5 because the log was filling up with LCP echo information. I still have the IP binding issue - "failed to set IPv4 address: File exists" after a tunnel is dropped and comes back up. I'm wondering if the I...

Hi dimka88, I've removed the framed-route and set the following settings in the Accel-ppp configuration file: [common] single-session=replace #sid-case=upper #sid-source=seq #max-sessions=1000 check-ip=1 [l2tp] verbose=1 #dictionary=/usr/local/share/accel-ppp/l2tp/dictionary hello-interval=60 timeou...

Hi @dimka88, Thank you for your reply. Regarding the Framed-Route, I moved to Accel-PPP from another platform where specifying a default route for each user was necessary. Are you saying this is not needed in this case? I must admit I was confused when looking at the forum earlier because it seemed ...

Hi @dimka88, Further to my last post, I believe I have a serious issue with interfaces not being deleted correctly and would appreciate your input. I am redistributing kernel routes. Please see examples from my frr.log and accel-ppp.log. It looks like when an L2TP session drops, it is not removed co...

Hi Everyone, I'm currently working on configuring ACCEL-PPP to function in both LAC and LNS modes simultaneously. While I see that it's possible to set ACCEL-PPP to operate in LAC mode, my goal is to have a setup where it can dynamically handle sessions based on specific criteria. Here’s what I need...

Hi Everyone, I've been encountering a persistent issue with my ACCEL-PPP setup and would appreciate any insights or suggestions. Here’s the problem: When an L2TP session is terminated or drops, it appears that the IP address assigned to that session is not removed from the LNS. This leads to the fol...

Hi Everyone, I'm hoping someone can guide me in resolving what seems to be a Buffer-bloat issue. I've been using tools such as 'https://devina.io/speed-test and have observed that TCP traffic through the L2TP tunnel, especially when loading websites, exhibits noticeable lag. Additionally, there have...

Hi @dimka88, Thank you once again for your guidance on configuring the gateway IP with ACCEL-PPP. Following your suggestion, I've set the gateway to one of the router's interfaces. However, this has made no difference. I am still observing a discrepancy in routing that I hope you can help me underst...
