Asus AC51U (padavan firmware) - LTE modem double NAT

[Ze Pequeno]

Hi!

I have two Asus AC-51-U with padavan's 3.4.3.9-099 firmware.

On the first one I have an old USB Modem huawei that works fine with connection type: USB Modem (RAS)

The second one I've a K4203 huawei USB modem that only works if I set up the connection type: USB Modem (NDIS/RDIS). But it don't let me open ports - double nat!

Is there any way to open ports on this? Or I have to change the USB modem for other one that works in RAS mode ?

Thank you very much!

I've changed the USB Modem (for an old one that works with connection type: USB Modem (RAS)) and it is working just fine right now.

AC51U with connection type: USB Modem (NDIS/RDIS) does double NAT and there is nothing I can do to solve it.

Over and out!
