Hello,

It would help if you could provide a picture with your network topology, device connections, IP addresses.

Also please check this configuration example. It is created on an older WebUI design, however, configurable settings should be smilar: https://wiki.teltonika-networks.com/view/L2TP_configuration_examples.

Next you can send me a troubleshoot file to view your configuration. To generate one, access router's WebUI, go to System -> Administration > Troubleshoot section and download troubleshoot file from there.

Best regards,

Žygimantas
