Hi
I have a router RUT240 and I want to configure it as VPN server, to be able to connect from outside.
The router is on 4G SIM card, with a public IP (static). I've followed this configuration example:
https://wiki.teltonika-networks.com/view/RUT240_L2TP_over_IPsec_(Windows_10)
but is not working. I can't connect from my windows to the router through VPN.
Firmware is latest one, just checked.
Error on windows is: The L2TP connection attempt failed because the security layer encountered a processing error during initial negotiations with the remote computer.
Do I need to do something else? Did I missed anything?
Thanks a lot for your help!
Gabriel.
