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?
