L2TP - encryption got out of sync

Thu Jul 24, 2014 3:08 pm

Hi,

I have a client who has a VPN to a service and the connection is very intermittent. I've advised that they should contact the provider. In the interim I've tested the service and cannot see any issue when testing via a DSL line. They make use of a wireless internet connection.

The errors I see are:
-----------------------------------------------
LCP receiveid ProtRej for unsupported protocol 0xc44c
packet Encryption got out of sync

LCP receiveid ProtRej for unsupported protocol 0x255f
rcvd LCP TermReq id=0x3
packet Encryption got out of sync
-----------------------------------------------

Any thoughts...

What's the latency on the WiFi link? Is the time on all devices synchronized e.g. using SNTP?
By 2016 total internet traffic will be 3x 2011

I have the same issue with the last 6.24 version of routeros x86 in vmware 5.5U2 in l2tp setup. and I can't find the solution to solve this problem right now. :(
