Hello,

Could you please share your GRE configurations? Make sure to blur/hide any sensitive information such as public IP addresses.

Also, could you please check routes on your RUT device from [CLI/SSH](https://wiki.teltonika-networks.com/view/Command_Line_Interfaces_RutOS)?:

```auto
ip r show table all
route -n

```

Kind Regards,
