Hallo
I just confugured L2TP tunnel over IPSec. I’m able to establish it if the device is inside LAN area. But whan I want to connect device from outside (via public IP) there is no L2TP response. (IPSec is established). Can anybody help me, please?

Hi,

What do you want to achieve? Do you want to enable road warriors to connect to your network or do you want to connect two routers?

For road warriors check out this thread: http://forum.mikrotik.com/t/solved-l2tp-ipsec-with-android/61619/1

Also watch the MUM presentation linked in Tomas’ signature to secure your VPN configuration.

Kind regards,

Thanks iBlueDragon,

I’ll have a look on that thread. Just to give all info. Need to enable road warriors.
