Hi,

I need a tunnel over a high latency link (Satellite, ~700ms). Layer 2 would be great.
So I tried a L2TP tunnel from one MikroTik to another one (without IPsec). Performance without tunnel is about 20MBit/s and with tunnel it drops to 1-2MBit/s. Sometimes a little better but not good.
Is there a way to analyze the problem?
Also tried EoIP Tunnel but this is even worse.
CPU Load on the local RB2011UiAS-RM is about 7% during download and nearly 0% at the CCR in datacenter.
I kept the default value for MTU/MRU and so on (1450 I think).
Do you have any suggestions for my needs?
Same tunnel works fine on a low latency ADSL link (~25ms with 50MBit/s -> ~47MBit/s)

Regards
Martin
