Hello,

 

Unfortunately, in the configuration TL-R600 & TL-R600, connection still drops (after a docker pull) and kill all connections on the main TL-R600 :-(.

As usual, no very interesting mesages in the log:

TL-R600 server: not even a disconnect message, only a IKE responder/phase1/phase2

TL-R600 client: no info of what happen, juste disconnected and IKE restart messages.

 

Still wait for a working solution...

Hello,

 

Yes, it seems more stable... But not enough to turn off band limitation...

As described at the very beginning of the post, it's a quiet simple architecture:

on a side:

[PCs] --- ethernet Gb/s --- (Egress/Ingress set to 10Mb/s) [ TPl client l2tp ] --- ethernet Gb/s --- [ internet box ] --- fiber 300Mb/s --- internet

on the other side:

[PC] --- ethernet Gb/s --- [TPl server l2tp ] --- ethernet Gb/s (set to 100Mb/s) --- internet

If nothing is set to limit bandwidth, the kill command is "docker pull" from the client side. Before this version, a long scp was sufficient to drop down tunnel...

 

Thanks for help but you have to understand I though buying a full working device and didn't plan to spend time to debug... And it seems there are other big issues (didn't tried with last version) like server accept l2tp connection without ipsec if client (from linux) ask for (of course ipsec encryption is not set to auto in TPl server)...

Hello - could you please send me a link to the same firmware? I am having the same issue that M.Ed reported

Hello M.Ed - would you mind sending me the same firmware? I am having the same issue and would like to try and see if that resolves the issue.

Same issue. IPSec VPN drops multiple times a day under heavy load. Upwards of a dozen times some days. Usually only drops for 20 seconds, but sometimes minutes. Seems to affect 1 office more than the other probably because its larger and creating the heavier load on the VPN. I say heavier, but its only a 7 RDP connections vs 2 RDP connections on the other site which seems to have significantly less issues. Running the current firmware 4.04-20200313 on TL-R600VPN.

Is this beta available publicly yet? Im having thr same issue with the same equipment.

Hi,

 

Well, I still have the problem... But there is no evidence it's because of the router...

What I observed is some UDP packets are dropped between the 2 points when I override a 20Mb/s limit... (of course nobody knows the reason of this limit ).

And, obviuosly, VPN use UDP packets... It means if I send big data from a lan to the other, packets will be encapsulated in UDP packets and if some are dropped tunnel could detect a shutdown of this tunnel...

To check that (the BW limitation), I used iperf3 from A to B and B to A without routers.

To limit the impact, I forced physical Ethernet to 10Mb/s which is not a good solution...
