Hi All, My Network Interface failed on my ACCEL-PPP/L2TP server. In the system log, I see loads of the following entries:- System-networkd[794] l2tp019: LINK UP System-networkd[794]: Gained carrier Kernel: [74442.582804] l2tp019: renamed from ppp68. Then I40e 0000:01:00.0: ARQ: Unknown event 0x0000 ...

Hi All,

Are there any tweaks such as buffers/sysctl or ethtool that will increase the performance of ACCEL?

Thanks,

Hi, I've got the following set under ppp:- min-mtu=1280 mtu=1500 mru=1500 I can't see such a setting under L2TP. When the L2TP tunnels establish, ifconfig l2tp00 etc. shows the mtu is 1420. The CPE connecting is set to 1500 and the path should allow 1500. if I type ifconfig l2tp00 mtu 1500, this wil...

Hi,

I'm using Ubuntu with a Xanmod Kernel 5.15.16-xanmod1

I've added the rules to my iptables as above. But a conntrack -D shows IP'a via the l2tp intefaces are still being tracked.

Any ideas how to fix this?

I would like to setup various rules to disable connection tracking for the l2tp interface. Normally I would do this by the interface name. However, in ACCEL-PPP the interface is not created until the first session comes in. I’ve set ifname=l2tp0%d to l2tp0 to make all interfaces l2tp0. I then want t...

Hi Dima, Thanks for the useful input. I’m now able to connect, when setting the accounting port to 0. I wonder if you can tell me how to find out why Radius accounting is not working? When the port is set to 1813 It records the session info in Daloradius before disconnecting. Perhaps Accel-ppp is no...

Users are able to connect to L2TP/ Accel-ppp and Radius provides IP address etc. However, Radius accounting fails and the session is then terminated after 3 tries. With the following cause code:- <Acct-Terminate-Cause NAS-Error>] In the Accel-PPP logs I see the following: - ( IP addresses changed fo...

Hi Dimka, Please see below example config, I have removed all the commented-out code and changed the IP addresses for security. I am using ACCEL-PPP as an L2TP LNS to my providers LAC/LTS. This is why I am using a shared secret. Previously when using L2TPNS I have been able to set the password and c...

Hi,

Has anyone been able to verify what I have found?

Is it a configuration issue on my side or a bug?

I would be most grateful for any help.
