L2TP IPSec RB1100AHx4 Packet Loss [Solved]

Hardware MikroTik hardware general

Hi all,

i have an CCR1009-7G-1C-1S+ since 4 weeks with 6 L2TP-IPSec tunnel.
Last week we have changed the CCR1009 against an RB1100AHx4. With the RB1100 we have 20 to 50 % packet loss.

RB1100 runs with bugfix 6.38.7 and current 6.39.2 with the same problem.

Today i have switched it back to CCR1009 which is running bugfix 6.37.5 and there is no packet loss!
Configuration es exactly the same.

Any ideas?

Thanks!

I have create an support case with supout.rif.
Problem is reproducible with an direct connection between RB1100AHx4 and RB750Gr3 without NAT or something.
An direct ping shows packet loss.

Hi all,

we have found an solution also it´s a little bit spacy…
The problem was not the RB1100AHx4 how i thought because against the CCR all RB750Gr3 worked as expected.

We have update the RB750Gr3 to 6.39.2 and that solved the problem!
