NAT Loopback stops working after some days - TP-Link TL-WDR4300 v1 - LEDE 17.01.4 r3560


Dunno if I m posting on right place, I have a TP-Link TL-WDR4300 with the latest LEDE version, it works fine but I need some port forwards to access external and internal.

When configured it worked great but after some days the NAT Loopback stopped working, so I was not able to access from LAN but from external was still ok, even disabling and re-enabling the function or restarting the OS the function never came back, the only way to make it work again was doing a hard reboot.

Is there sometingthat I would make different?
