Hi I have a project that I am trying to connect 11 remote devices to a local server via pptp vpn. I have 11 rut240 with SIM cards next to each remote device making pptp client dial out to a MikroTik router next to the server .

Everything seems to be fine only if I lock rut240 to use 3g and not lte mobile connection.

If I use auto and rut connect to lte I am losing connectivity  from server to the device behind rut.  I can ping both sides but I am losing web interface of rut and remote device.

I have spend many hours trying to figure if any firewall rule fails on lte but no luck.

Any idea?

Hi,

Could you check what IP get router when LTE and 3G is used.

Have you tried with another GSM provider SIM card?
